1550 nm FP Laser Diode Epi-Wafer
The 1550 nm Fabry-Perot (FP) laser diode (LD) epi-wafer, designed especially for the high-speed fiber-optic communications, is grown by metal-organic chemical vapor deposition (MOCVD) by HYRD, with strained InAlGaAs or InGaAsP multiple quantum wells (MQWs) as the active layer.
