Abstract

Feature Issue on Optical Performance Monitoring (OPM). A compact and cost-effective device for monitoring wavelengths and power levels of WDM channels labeled with pilot tones is presented. The device utilizes a tunable silicon etalon and a simple sampling scheme to identify and analyze the channels directly from the optical multiplex. The operation is demonstrated in a four-channel system. Extension to a large number of WDM channels is evaluated through simulations.
