These compounds are members of the "III-V" group of semiconductors-that is, compounds product of elements listed in columns III and V of the periodic desk. Varying the exact composition of the semiconductor can alter the wavelength (and subsequently the color) of the emitted gentle. LED emission is usually in the seen a part of the light spectrum (i.e., with wavelengths from 0.Four to 0.7 micrometer) or in the near-infrared section (with wavelengths between 0.78 and 2.5 micrometers).

Any LED can be used as a light supply for a short-range fiber-optic transmission system-that's, over a distance of less than a hundred meters (330 ft). For lengthy-vary fiber optics, nevertheless, the emission properties of the sunshine supply are selected to match the transmission properties of the optical fiber, and on this case the infrared LEDs are a greater match than the visible-mild LEDs. Glass optical fibers suffer their lowest transmission losses within the infrared region at wavelengths of 1.3 and 1.55 micrometers. To match these transmission properties, LEDs are employed which are made of gallium indium arsenide phosphide layered on a substrate of indium phosphide.
