Acronym for Light Amplification by Stimulated
Emission of Radiation. A light source that generates
coherent light through stimulated emission.

Displacement of the central wavelength of a laser
during one single pulse.

Transmitter diode based on semiconductor materials
which emits a threshold current of coherent light
(stimulated emission).

Conditions under which light is injected into an optical
waveguide. They are important for the further dispersion
of the optical power in the optical waveguide.

Type of wave that is attenuated through radiation
along the fiber and is in the marginal area between
guided modes of a fiber and the non-propagatable
light waves.

A semiconductor component that emits incoherent
light by means of spontaneous emission.

Method to reduce the phase space volume in a multimode
fiber with the aim of achieving an approximate
equilibrium mode distribution.

Singlemode fiber with a low attenuation coefficient
in the wavelength range between the 2nd
and 3rd optical window by reducing the OH peak
at the wavelength of 1383 nm.
