Power monitor

Power monitor

The integrated power monitor module is a freespace integration of a wideband optical tap coupler and a photodiode for power monitoring in any optical-fiber system. The pin photodetector in a TO-can package is hermetically sealed inside the hybrid device. The tap coupler uses an interference filter. Typical polarization-dependent loss is 0.03 dB and pin linearity is <10%. The device can be integrated into an edfa, transmitter, add/drop, or wdm system.
