| Zusammenfassung: | The invention relates to an optical power monitoring device for a photodiode assembly, which converts the DC component of a photodiode's bias current into a common mode voltage indicative of the average optical power of the incident light. The photodiode assembly, which is mountable in a conventional four-lead TO can package, includes a photodiode, a pre-amplifier, and a common mode voltage controller. The common mode voltage is added to the differential voltage, and the combined signal is output via the two data signal leads of the TO can package. |
