Tromborg was born in Give, Denmark. In 1968, he received the M.Sc. degree in physics and mathematics from the Niels Bohr Institute, in Copenhagen, Denmark. He was a university researcher studying high-energy particle physics from 1968 to 1978. In 1979, he joined the research laboratory of the Danish Teleadministrations in Copenhagen. He was Head of Optical Communications Department at Tele Danmark Research, Horsholm, Denmark from 1987 to 1995.
He was an adjunct professor at the Niels Bohr Institute from 1991 to 2001. In 1997, he took a leave of absence at the Technion - Israel Institute of Technology. Until his retirement at the end June 2006, he was a research professor at COM•DTU, Department of Communications, Optics and Materials (which became DTU Fotonik, Department of Photonics Engineering, in 2008 and DTU Electro, Department of Electrical and Photonics Engineering, in 2022), Technical University of Denmark.

Tromborg co-authored a research monograph and approximately one hundred journal and conference publications, mostly on physics and optoelectronics.
At the Niels Bohr Institute, he carried out research in elementary particle physics, particularly analytic S-matrix theory and electromagnetic corrections to hadron scattering. He coauthored a research monograph on dispersion theory.
In the early 1980s, he switched to photonics. Tromborg was one of the first to develop advanced theoretical models for complex semiconductor laser structures such as external laser cavities and distributed feedback lasers in the beginning of the 1980s. Computer simulations and measurements confirmed the validity of the theoretical models and their predictions. Several co-workers including Henning Olesen, Gunnar Jacobsen, Jens Henrik Osmundsen, Finn Mogensen, Kristian Stubkjær, Jesper Mørk, Xing Pan, Hans Erik Lassen and Björn Jónsson contributed to this work over a period of almost 15 years until 1995.
At TeleDanmark Research in the late 1980s and early 1990s Tromborg and colleagues worked to study the dynamics of active semiconductor materials in order to understand the physical relaxation processes at play, their strength and characteristic time scales. A pump-probe set-up employing femtosecond lasers was established and modeling efforts were initialized. Tromborg led the effort to identify this as a topic that would remain important for many years and argued that Denmark should work to lead in the field. He also proposed theoretical methods that could be used to estimate the size of these ultrafast dynamical effects and their role in understanding the origin of nonlinear gain suppression in semiconductor lasers.
From 1999 to his retirement at the end of June 2006, Tromborg was with the Department of Communications, Optics and Materials (COM*DTU) at the Technical University of Denmark. In this period, he worked in both research and education, as well as in securing several European Union research projects for COM*DTU. Tromborg took up the field of photonic crystals and initiated and contributed himself to activities within the theory of photonic crystals. He also applied general techniques within stochastic theory and signal analysis to develop improved descriptions of noise spectra in nonlinear semiconductor optical amplifiers.
Tromborg received the Electro-prize from the Danish Society of Engineers in 1981.[ citation needed ]
He was Chairman of the Danish Optical Society from 1999 to 2002. [3]
He has been Associate Editor of the IEEE Journal of Quantum Electronics since 2003.
At his retirement, a symposium on photonics was held in his honor on 22 June 2006 at the Technical University of Denmark. [4]
Atomic, molecular, and optical physics (AMO) is the study of matter–matter and light–matter interactions, at the scale of one or a few atoms and energy scales around several electron volts. The three areas are closely interrelated. AMO theory includes classical, semi-classical and quantum treatments. Typically, the theory and applications of emission, absorption, scattering of electromagnetic radiation (light) from excited atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter in general, fall into these categories.
The Niels Bohr Institute is a research institute of the University of Copenhagen. The research of the institute spans astronomy, geophysics, nanotechnology, particle physics, quantum mechanics, and biophysics.
The Technical University of Denmark, often simply referred to as DTU, is a polytechnic university and school of engineering. It was founded in 1829 at the initiative of Hans Christian Ørsted as Denmark's first polytechnic, and it is today ranked among Europe's leading engineering institutions. It is located in the town Kongens Lyngby, 12 kilometres (7.5 mi) north of central Copenhagen, Denmark.
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Photonics is closely related to quantum electronics, where quantum electronics deals with the theoretical part of it while photonics deal with its engineering applications. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
Eli Yablonovitch is an American physicist and engineer who, along with Sajeev John, founded the field of photonic crystals in 1987. He and his team were the first to create a 3-dimensional structure that exhibited a full photonic bandgap, which has been named Yablonovite. In addition to pioneering photonic crystals, he was the first to recognize that a strained quantum-well laser has a significantly reduced threshold current compared to its unstrained counterpart. This is now employed in the majority of semiconductor lasers fabricated throughout the world. His seminal paper reporting inhibited spontaneous emission in photonic crystals is among the most highly cited papers in physics and engineering.
Quantum optics is a branch of atomic, molecular, and optical physics dealing with how individual quanta of light, known as photons, interact with atoms and molecules. It includes the study of the particle-like properties of photons. Photons have been used to test many of the counter-intuitive predictions of quantum mechanics, such as entanglement and teleportation, and are a useful resource for quantum information processing.
Nikolay Gennadiyevich Basov was a Russian Soviet physicist and educator. For his fundamental work in the field of quantum electronics that led to the development of laser and maser, Basov shared the 1964 Nobel Prize in Physics with Alexander Prokhorov and Charles Hard Townes.
Robin K. Bullough was a British mathematical physicist known for his contributions to the theory of solitons, in particular for his role in the development of the theory of the optical soliton, now commonly used, for example, in the theory of trans-oceanic optical fibre communication theory, but first recognised in Bullough's work on ultra-short optical pulses. He is also known for deriving exact solutions to the nonlinear equations describing these solitons and for associated work on integrable systems, infinite-dimensional Hamiltonian systems, and the statistical mechanics for these systems. Bullough also contributed to nonlinear mathematical physics, including Bose–Einstein condensation in magnetic traps.

Anthony Michael Johnson is an American experimental physicist, a professor of physics, and a professor of computer science and electrical engineering at the University of Maryland, Baltimore County (UMBC). He is the director of the Center for Advanced Studies in Photonics Research (CASPR), also situated on campus at UMBC. Since his election to the 2002 term as president of the Optical Society, formerly the Optical Society of America, Johnson has the distinction of being the first and only African-American president to date. Johnson's research interests include the ultrafast photophysics and nonlinear optical properties of bulk, nanostructured, and quantum well semiconductor structures, ultrashort pulse propagation in fibers and high-speed lightwave systems. His research has helped to better understand processes that occur in ultrafast time frames of 1 quadrillionth of a second. Ultrashort pulses of light have been used to address technical and logistical challenges in medicine, telecommunications, homeland security, and have many other applications that enhance contemporary life.
