Waveguide based component optical signal power and wavelength detector

摘要

A planar waveguide monitor is shown for determining the wavelength and power of component optical signals of a multiplexed optical signal. The monitor includes an optical waveguide router similar to a Dragone router with at least twice as many output waveguides as the number of component optical signals. An array of optical detectors is disposed to detect output optical signals from the output waveguides. The optical detectors produce a plurality of electrical output signals corresponding to the power of each detected output optical signal. The monitor includes a programmable computer to compare the electrical output signals to a predetermined set of output responses. The power and wavelength of each component optical signal of the multiplexed optical signal may be determined from this comparison.
