VCSEL Epi-Structure

VCSEL is a semiconductor laser diode comprised of epitaxial layers grown on n-type GaAs or InP substrates by molecular beam epitaxy (MBE) or metal-organic chemical vapor deposition (MOCVD). The VCSEL structure consists of Fabry-Perot cavity (resonator) including an active region with several quantum wells, where light is generated, and top and bottom DBRs (Distributed Bragg Reflector). DBR is composed of stack of semiconductor layers (each with a thickness of a quarter of the laser wavelength) that reflect a particular range of light wavelengths. The emitted light leaves the device in a direction perpendicular to its surface. Learn more.

InGaAs Wafers

The so-called InGaAs material refers to a complete epitaxial stack composed of a variety of layers, with InGaAs forming the key part – the absorption – and being responsible for the material’s optical properties. The InGaAs layer itself is a III-V semiconductor that belongs to the family of In(x)Ga(1-x)As(y)P(1-y). For binary GaAs, InP, GaP, or InAs, the x and y are set to 0 or 1. In quaternary InGaAsP and ternary InGaAs a variety of x and y values are possible, and each combination will tune the semiconductor to different applications. Learn more.
