Adelphi University Plans Master’s Program in Optical Physics

Beginning this fall, Adelphi University in Garden City, N.Y., will offer a master’s degree program in physics with a concentration in optics. The research-oriented 30-credit program is targeted to recent graduates as well as to working professionals who hold a bachelor’s degree in science, engineering or other related discipline. Adelphi’s facilities include equipment for investigation in lasers and optics, nonlinear optics, quantum optics, laser cooling and trapping, flame diagnostics, and nano- and energy technologies.

There are 447 suppliers of Optics in the Photonics Marketplace.

Glossary

laser cooling: Laser cooling is a technique used to reduce the temperature of a material or a collection of atoms or molecules by using laser light. It is based on the principle of selective absorption and emission of photons by atoms or molecules. In laser cooling, specially tuned laser beams are directed at the material or atoms. When these atoms absorb photons from the laser light, they gain momentum in the direction of the laser beam due to the momentum carried by the photons. However, according to...
nano: An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
photonics: The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
quantum optics: The area of optics in which quantum theory is used to describe light in discrete units or "quanta" of energy known as photons. First observed by Albert Einstein's photoelectric effect, this particle description of light is the foundation for describing the transfer of energy (i.e. absorption and emission) in light matter interaction.
