VCSEL Laser Wafer Chip

PAM-XIAMEN offer 850 nm,850nm and 940nm VCSEL(vertical-cavity surface-emitting laser) epitaxial wafer for the tele communication, gesture recognition,3D imaging and other applications, which is grown by MOCVD by with GaAs/AlGaAs multiple quantum wells (MQWs) as the active layer.

We have three items: VCSEL epitaxial wafer(3”,4”), VCSEL Uncleaved wafer but taped out and tested,6”(you can cut it and use them directly), VCSEL Wafer Die.
