ABSTRACT:
A long wavelength VCSEL with a photodetector, wherein the VCSEL includes a first and second stack of DBRs disposed on a first surface of a first substrate element, having an active region sandwiched therebetween, and a PIN photodetector including a first doped region disposed on a second substrate element, a undoped region disposed on the first doped region, and a second doped region disposed on the undoped region. The PIN photodetector is mounted to an opposed surface of the first substrate element, thereby monitoring a back VCSEL emission. The device is fabricated to allow for automatic power control (APC) of the VCSEL.
