Waveguide A 2 dimensional substrate which carries light in channels inscribed in the material.

Wavelength Distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. Wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6 m).

Wavelength dependence The variation in an optical parameter caused by a change in the operating wavelength.

Wavelength Division Multiplexer A passive fiber optical device used to separate optical signals of different wavelengths carried on 1 fiber optic cable.
