Manijeh Razeghi is an Iranian-American scientist in the fields of semiconductors and optoelectronic devices. She is a pioneer in modern epitaxial techniques for semiconductors such as low pressure metalorganic chemical vapor deposition (MOCVD), vapor phase epitaxy (VPE), molecular beam epitaxy (MBE), GasMBE, and MOMBE. These techniques have enabled the development of semiconductor devices and quantum structures with higher composition consistency and reliability, leading to major advancement in InP and GaAs based quantum photonics and electronic devices, which were at the core of the late 20th century optical fiber telecommunications and early information technology. [1]
Her current research interests involve many cutting-edge technologies including III-Nitride semiconductor devices, quantum cascade lasers, quantum well infrared photodetectors (QWIP), and self assembled quantum dot devices. [2]
Razeghi received a bachelor's degree in nuclear physics from Tehran University, then her doctorate from Université de Paris, France. In 1986, she became the head of Thomson-CSF Exploratory Materials Lab and made a major contribution to the field of semiconductor physics when she developed metalorganic chemical vapor deposition (MOCVD) epitaxial technique and published her pioneering work on InP in her book "The MOCVD Challenge Volume 1: A Survey of GaInAsP-InP for Photonic and Electronic Applications" (Adam Hilger Press, 1989). [3]
In 1991, Razeghi moved to the US to become the Walter P. Murphy Professor and director of the Center for Quantum Devices, Department of Electrical Engineering and Computer Science, Northwestern University, [4] where she continued her research in a broad range of quantum devices such as lasers and photodetectors. In 1995, she published her second book "The MOCVD Challenge Volume 2: A Survey of GaInAsP-GaAs for Photonic and Electronic Device Applications" (Institute of Physics Publishing, 1995). [5]
In 2018, Professor Razeghi won the Benjamin Franklin Medal for Electrical Engineering for "the realization of high-power terahertz frequency sources operating at room temperature [6] using specially designed and manufactured semiconductor lasers, which enables a new generation of imagers, chemical/biological sensors, and ultra-broadband wireless communication systems." [7] She developed lasers that can detect explosives and pathogens [8] [9] as well as electronic devices that will eventually deliver turbo-charged, super-fast WiFi.[ citation needed ]
She holds 60 patents [10] and has published 20 books [11] and more than 1000 papers. [12] Prof. Razeghi continues to make great academic contribution at Northwestern. She created both graduate and undergraduate programs in solid-state engineering (SSE), and has supervised over 50 PhD students and over 20 Master's students.
A laser diode is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in the form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing.
The vertical-cavity surface-emitting laser is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers which emit from surfaces formed by cleaving the individual chip out of a wafer. VCSELs are used in various laser products, including computer mice, fiber-optic communications, laser printers, Face ID, and smartglasses.
Quantum-cascade lasers (QCLs) are semiconductor lasers that emit in the mid- to far-infrared portion of the electromagnetic spectrum and were first demonstrated by Jérôme Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson, and Alfred Cho at Bell Laboratories in 1994.
Federico Capasso is an Italian-American applied physicist and is one of the inventors of the quantum cascade laser during his work at Bell Laboratories. He is currently on the faculty of Harvard University.
A hybrid silicon laser is a semiconductor laser fabricated from both silicon and group III-V semiconductor materials. The hybrid silicon laser was developed to address the lack of a silicon laser to enable fabrication of low-cost, mass-producible silicon optical devices. The hybrid approach takes advantage of the light-emitting properties of III-V semiconductor materials combined with the process maturity of silicon to fabricate electrically driven lasers on a silicon wafer that can be integrated with other silicon photonic devices.
Dmitri Z. Garbuzov was one of the pioneers and inventors of room temperature continuous-wave-operating diode lasers and high-power diode lasers.
