Official Description

Theoretical approach to quantum mechanics and atomic physics, with many applications in spin resonance and modern maser theory. Course Information: Prerequisite: PHYS 485 recommended.

Subject Area

Microelectronics and Photonics

Course Director


Lectures and discussions on quantum electronics, density-matrix theory, rate equation, and the generation of coherent electromagnetic radiation. Applications to specific laser systems.


Theoretical introduction to quantum mechanics, quantum optics, and microcavity lasers, with many applications in photonics and laser theory. Prerequisite: PHYS 485 or equivalent introduction to quantum mechanics is recommended.


Lectures and discussions on quantum optoelectronics, quantum mechanics, second quantization, density-matrix theory, and generation of coherent electromagnetic radiation, and confinement within photonic micro- and nano-cavities. Included is the study of the interaction of radiation with atomic systems: density-matrix theory, spontaneous and induced transitions, gain coefficient, quantum theory of Einstein A and B coefficients, homogenous and inhomogenous broadening. We also review coherent interactions of a radiation field and an atomic system: two-level atom with quantized field, electromagnetically induced transparency, lasing without inversion. Applications to laser oscillators: general laser theory, rate equations, threshold condition, lasing inversion, and semiconductor gain. Specific laser systems will included atomic, semiconductor lasers, microcavity lasers, and nanocavity lasers. Finally, nanophotonic effects such as Fabry-Perot cavities, Purcell effect, vertical cavity lasers, photonic crystal nanocavities will also be discussed.


Principles of Quantum Mechanics (Schrodinger picture, harmonic oscillator, operators as matrices, density matrix, Heisenberg & Interaction pictures, parity-time symmetry photonics)

Semiclassical Interaction of Radiation and Matter (Dipole interaction Hamiltonian, 2-level system: probability amplitude, 3-level system: coherent trapping, Dipole interaction using density matrix, susceptibility from density matrix)

Quantization of Radiation Field (Harmonic oscillator formulism, representations of field operators, squeezed light, entanglement)

Fully Quantized Interaction of Radiation and Matter (Dipole interaction of radiation with electron, spontaneous & stimulated transitions, quantized interaction using operator method)

Midterm Exam

Optical Microcavities and Gain (Bulk semiconductor optical gain via density matrix, nanostructure optical gain, Heisenberg picture of semiconductor gain)

Fabry-Perot Microcaviy Lasers (Fabry-Perot cavity, VCSELs, distributed Bragg reflectors, cavity resonance/gain bandwidth alignment (spatial and spectral), transverse optical phenomena)

Cavity Quantum Electro-Dynamics (Weak cavity coupling, strong cavity coupling, exciton-photon strong coupling, photon statistics)

Optical Nanocavity Lasers (Whispering gallery cavities, photonic crystals and cavities, metallic and plasmonic cavities)

Detailed Description and Outline

Lectures and discussions on quantum optoelectronics, quantum mechanics, second quantization, density-matrix theory, and generation of coherent electromagnetic radiation, and confinement within photonic micro- and nano-cavities. In addition a term paper will be researched and should be a written review of a quantum optoelectronic or quantum optic topic, using at least three journal or technical book references. You cannot cover the topic of your thesis research, nor can you cover a topic included in the course lectures. Your term paper topic must involve the interaction of light with matter and must describe a quantum mechanical phenomenon with a discussion of its physical interpretation. Please include in your paper a mathematical derivation with equations of a quantum mechanical result with enough detail and explanation that the reader (me!) can understand your analysis.

The paper should include an introduction which motivates why the reader should be interested in your topic and an explicit description of the paper structure. Your paper should exhibit organizational structure with topic motivation, discussion, the derivation, figures, and properly cited references. The paper should be no more than 10 pages in length (including figures but not including references) with double spaced single column format, 12 pt. font, and employ correct English grammar.

Computer Usage

Some homework requires numercial calculations.


Multiple homework report (about every two weeks) and one term paper.
