Optical Communications Gallium Arsenide Substrate LEDs
2inch GaAs (100) Undoped Substrates
Overview
Gallium arsenide is used in the manufacture of light-emitting diode s (LEDs), which are found in optical communications and control systems. Gallium arsenide can replace silicon in the manufacture of linear ICs and digital ICs. Linear (also called analog ) devices include oscillator s and amplifier s. Digital devices are used for electronic switching, and also in computer systems.
