33Oscillator phase noise — For more general information, see Phase noise. Oscillators inherently produce high levels of phase noise. That noise increases at frequencies close to the oscillation frequency or its harmonics. With the noise being close to the oscillation… …
34Optical coherence tomography — Intervention Optical Coherence Tomography (OCT) image of a sarcoma MeSH …
35Tunable laser — A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength… …
36Nondimensionalization — is the partial or full removal of units from an equation involving physical quantities by a suitable substitution of variables. This technique can simplify and parameterize problems where measured units are involved. It is closely related to… …
37SONOS — SONOS, short for Silicon Oxide Nitride Oxide Silicon , is a type of high performance non volatile computer memory. It is similar to the widely used Flash RAM, but offers lower power usage and a somewhat longer lifetime. SONOS is being developed… …
38McCumber relation — The McCumber relation (or McCumber theory) refers to the effective cross sections of absorption and emission of light in the physics of solid state lasers [1][2]. Contents 1 Definition 2 Gain …
39Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… …
