The PL-VCSEL-1-A81 850nm VCSEL is a vertical emitting MOVPE grown GaAsP/AlGaAs Single Mode diode laser. Wavelength tuning can be achieved via laser current and temperature tuning. package with TEC and PD Built in. Our 850 nm single mode VCSEL is designed for high-speed, high-performance communication applications.
