摘要： Consistent with the present disclosure a compact, integrated tunable filter is provided that can adjust the power levels of optical signals output from an optical amplifier, for example, so that the amplifier has a uniform spectral gain. The tunable optical filter includes a planar lightwave circuit (PLC) having cascaded Mach-Zehnder interferometers, each of which having corresponding differential optical delays. At least one of the differential optical delays is different than the rest. Alternatively, the differential optical delays are different from one another. Each of the Mach-Zehnder interferometers is connected to one another by a tunable optical coupler. Such a filter has an improved frequency response in that the number of shapes that the transmission spectrum may have is increased. Accordingly, the optical filter may be more finely tuned to more effectively flatten, for example, the output of the optical amplifier. In addition, since the tunable optical filter is realized with a planar lightwave circuit (PLC) component, manufacturing costs can be reduced, and a more compact device can be obtained.

摘要： A multi-channel dispersion compensator comprising an optical signal waveguide that forms an input end for receiving an optical signal and an output end for providing a filtered optical signal. The multi-channel dispersion compensator also includes a series of closed-loop resonators providing frequency delay to at least one channel of the optical signal. The optical signal waveguide and each closed-loop resonator form a tunable coupler having a coupling value. The coupling value for each tunable coupler is selected to minimize constant dispersion and linear slope dispersion of the optical signal. Methods of fabrication and use are also described.

摘要： A tunable optical demultiplexer includes a control circuit and one or more heaters thermally coupled to waveguides of an optical demux. The control circuit is in signal communication with the one or more heaters and includes a processor coupled to a memory. The control circuit is configured to receive an optical channel group (OCG) identification signal and adjust the power delivered to the heaters in response to the OCG identification signal and based on parameter values stored in the memory. The optical demux outputs a plurality of optical signals at a corresponding one of a plurality of outputs. The transmission characteristics of the optical demux are varied depending on the amount of power delivered to the heaters. The varying of the transmission characteristics of the optical demux adjusts the spectral shifting of the plurality of wavelengths output by the optical demux.
