Andrew Marc Weiner OSA NAE NAI (Born July 25, 1958-2024) was an American electrical engineer, educator and researcher known for contributions to the fields of ultrafast optics and optical signal processing. He was the Scifres Family Distinguished Professor of Electrical and Computer Engineering at Purdue University.
Weiner received a Sc.D. in electrical engineering in 1984 from the Massachusetts Institute of Technology. [5] Following graduation he joined Bellcore, then a premier telecommunications research and development company, eventually serving as Manager of Ultrafast Optics and Optical Signal Processing Research. In 1992, Weiner was appointed at professor rank at the School of Electrical and Computer Engineering at Purdue University.
Weiner’s research in ultrafast optics focuses on the processing of extremely high-speed lightwave signals as well as their application to the generation and manipulation of ultrabroadband radio-frequency signals. He is most well-known for research on the development of Fourier synthesis methods for controlling the shape of femtosecond light pulses. [6] [7] [8] These methods extend femtosecond pulse generation technology by providing the ability to engineer these pulses into complex phase- and amplitude-modulated ultrafast optical waveforms according to specification. Findings from Weiner’s research have been applied in fiber optic networks and in ultrafast optical science laboratories around the world. Specific studies in recent years address quantum photonics, [9] [10] [11] Kerr comb generation in on-chip microresonators, [12] [13] [14] and microwave and millimeter wave photonics. [15] [16] [17] Weiner authored the textbook Ultrafast Optics (Wiley, 2009), and served as editor in chief of Optics Express, the largest journal broadly covering optics and photonics, from 2013 to 2018. [18]
In 2008, Weiner was elected to the U.S. National Academy of Engineering, “for contributions to the development of femtosecond optical-pulse shaping technology.” [19] He is a Fellow of the National Academy of Inventors (2016), [20] the Optical Society of America (1990) [21] and the Institute of Electrical and Electronics Engineers (IEEE) (1995). [22] He received a National Security Science and Engineering Fellowship, now called the Vannevar Bush Faculty Fellowship, [23] from the U.S. Department of Defense in 2009. [24] He has received the Optical Society of America’s Adolph Lomb Medal (1990) in recognition of his early career achievements, [25] the International Commission for Optics Prize (1997), [26] the Alexander von Humboldt Foundation Research Award for Senior U.S. Scientists (2000), [27] the IEEE Photonics Society’s Quantum Electronics Award (2011), [28] and Optica's Charles Hard Townes Medal (2023). [29] Weiner is the co-recipient (with Jonathan Heritage) of both the Optical Society of America’s R. W. Wood Prize (2008) [30] and the IEEE Photonics Society’s William Streifer Scientific Achievement Award (1999). [31] He was also recognized by Popular Science Magazine for one of the "Top 100 Inventions of 1988" for the 100-femtosecond all-optical switch. [32]
Weiner has received numerous awards from Purdue University. He was awarded the Herbert Newby McCoy Award (2013), [33] which is the most prestigious award given by the university in natural sciences. [34] He is also the inaugural recipient of the College of Engineering’s Research Award (2003). [35] In recognition of his mentorship, Weiner received the Purdue University Provost’s Award for Outstanding Graduate Mentor (2008) [36] and the College of Engineering Mentorship Award (2014).
Weiner was a Hertz Fellow at MIT [37] and a recipient of the Hertz Foundation Doctoral Thesis Prize. [38]
In addition to his technical interests, Weiner has had a lifelong interest in martial arts, and holds black belt rank in Aikido and Judo.
In optics, an ultrashort pulse, also known as an ultrafast event, is an electromagnetic pulse whose time duration is of the order of a picosecond or less. Such pulses have a broadband optical spectrum, and can be created by mode-locked oscillators. Amplification of ultrashort pulses almost always requires the technique of chirped pulse amplification, in order to avoid damage to the gain medium of the amplifier.
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing. For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers.
A fiber laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
A frequency comb or spectral comb is a spectrum made of discrete and regularly spaced spectral lines. In optics, a frequency comb can be generated by certain laser sources.
Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems. The silicon typically lies on top of a layer of silica in what is known as silicon on insulator (SOI).
In optics, femtosecond pulse shaping refers to manipulations with temporal profile of an ultrashort laser pulse. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate complex pulses.
An ultrashort pulse laser is a laser that emits ultrashort pulses of light, generally of the order of femtoseconds to one picosecond. They are also known as ultrafast lasers owing to the speed at which pulses "turn on" and "off"—not to be confused with the speed at which light propagates, which is determined by the properties of the medium, particularly its index of refraction, and can vary as a function of field intensity and wavelength.

An optical transistor, also known as an optical switch or a light valve, is a device that switches or amplifies optical signals. Light occurring on an optical transistor's input changes the intensity of light emitted from the transistor's output while output power is supplied by an additional optical source. Since the input signal intensity may be weaker than that of the source, an optical transistor amplifies the optical signal. The device is the optical analog of the electronic transistor that forms the basis of modern electronic devices. Optical transistors provide a means to control light using only light and has applications in optical computing and fiber-optic communication networks. Such technology has the potential to exceed the speed of electronics, while conserving more power. The fastest demonstrated all-optical switching signal is 900 attoseconds, which paves the way to develop ultrafast optical transistors.
Time stretch dispersive Fourier transform (TS-DFT), otherwise known as time-stretch transform (TST), temporal Fourier transform or photonic time-stretch (PTS) is a spectroscopy technique that uses optical dispersion instead of a grating or prism to separate the light wavelengths and analyze the optical spectrum in real-time. It employs group-velocity dispersion (GVD) to transform the spectrum of a broadband optical pulse into a time stretched temporal waveform. It is used to perform Fourier transformation on an optical signal on a single shot basis and at high frame rates for real-time analysis of fast dynamic processes. It replaces a diffraction grating and detector array with a dispersive fiber and single-pixel detector, enabling ultrafast real-time spectroscopy and imaging. Its nonuniform variant, warped-stretch transform, realized with nonlinear group delay, offers variable-rate spectral domain sampling, as well as the ability to engineer the time-bandwidth product of the signal's envelope to match that of the data acquisition systems acting as an information gearbox.

Integrated quantum photonics, uses photonic integrated circuits to control photonic quantum states for applications in quantum technologies. As such, integrated quantum photonics provides a promising approach to the miniaturisation and scaling up of optical quantum circuits. The major application of integrated quantum photonics is Quantum technology:, for example quantum computing, quantum communication, quantum simulation, quantum walks and quantum metrology.
Kerr frequency combs are optical frequency combs which are generated from a continuous wave pump laser by the Kerr nonlinearity. This coherent conversion of the pump laser to a frequency comb takes place inside an optical resonator which is typically of micrometer to millimeter in size and is therefore termed a microresonator. The coherent generation of the frequency comb from a continuous wave laser with the optical nonlinearity as a gain sets Kerr frequency combs apart from today's most common optical frequency combs. These frequency combs are generated by mode-locked lasers where the dominating gain stems from a conventional laser gain medium, which is pumped incoherently. Because Kerr frequency combs only rely on the nonlinear properties of the medium inside the microresonator and do not require a broadband laser gain medium, broad Kerr frequency combs can in principle be generated around any pump frequency.

A virtually imaged phased array (VIPA) is an angular dispersive device that, like a prism or a diffraction grating, splits light into its spectral components. The device works almost independently of polarization. In contrast to prisms or regular diffraction gratings, the VIPA has a much higher angular dispersion but has a smaller free spectral range. This aspect is similar to that of an Echelle grating, since it also uses high diffraction orders. To overcome this disadvantage, the VIPA can be combined with a diffraction grating. The VIPA is a compact spectral disperser with high wavelength resolving power.
