An integrated optical tap monitor takes the form of a highly-reflective outer coating disposed over the active region of an associated photodetector. The coating is of a material that allows for a majority of the impinging optical signal to be re-directed into an output path, while passing a small portion of the signal into the photodetector's active region for monitoring purposes. The integrated configuration is small enough to be housed within a standard TO can, and additional optical components (filters, attenuators, etc.) may be co-located with the integrated tap monitor. By virtue of incorporating the monitoring function with a reflective surface, the integrated tap monitor may be substituted for a turning mirror at any place along a signal path and provide the benefit of power monitoring while also performing signal re-direction.
