Monitoring power in optical networks |
摘要 |
An optical network may include a detector for detecting the power of each of a plurality of channels of a wavelength division multiplexed optical signal in one embodiment of the present invention. Each channel may be conveyed to an interface underneath a detector by way of a core formed in the substrate. The interface may include a trench with one side surface angled to form a reflector to reflect light upwardly to be detected by the detector. Other surfaces of said trench may also be reflective to reduce the cross talk between adjacent channels.
