pulse broadening
1Ultrashort pulse — In optics, an ultrashort pulse of light is an electromagnetic pulse whose time duration is on the order of the femtosecond (10 − 15 second). Such pulses have a broadband optical spectrum, and can be created by mode locked oscillators. They are… …
2Material dispersion coefficient — In an optical fiber, the material dispersion coefficient, M(λ), characterizes the amount of pulse broadening by material dispersion per unit length of fiber and per unit of spectral width. It is usually expressed in picoseconds per… …
3True time delay — (TTD) is an electrical property of a transmitting apparatus and refers to invariance of time delay with frequency or to linear phase progression with frequency. TTD is an important characteristic of lossless and low loss, dispersion free,… …

5Nuclear magnetic resonance — This article is about the physical phenomenon. For its use as a method in spectroscopy, see Nuclear magnetic resonance spectroscopy. NMR redirects here. For other uses, see NMR (disambiguation). First 1 GHz NMR Spectrometer (1000 MHz,… …
6Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
7Solid-state nuclear magnetic resonance — (NMR) spectroscopy, characterized by the presence of anisotropic (directionally dependent) interactions.IntroductionBasic conceptsA spin interacts with a magnetic or an electric field. Spatial proximity and/or a chemical bond between two atoms… …
8Self-phase modulation — (SPM) is a nonlinear optical effect of light matter interaction.An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. This variation in refractive index… …
9Soliton (optics) — In optics, the term soliton is used to refer to any optical field that does not change during propagation because of a delicate balance between nonlinear and linear effects in the medium. There are two main kinds of solitons: spatial solitons:… …
10Mamyshev 2R regenerator — The Mamyshev 2R regenerator is an all optical regenerator used in optical communications. In 1998, Pavel V. Mamyshev of Bell Labs proposed and patented the use of the self phase modulation (SPM) for single channel optical pulse reshaping and re… …
