| 英文摘要 | A thermo-optic device and a method for using it are described. The device has a substrate including a pair of waveguides coupled at first and second coupling regions. At the first coupling region, an input signal is split between the two waveguides. Between the coupling regions on one of the waveguides is a demultiplexer, at least one phase shifting device, and a multiplexer. The signal portions recombine at the second coupling region. Heater strips at the first and second coupling regions alter the temperature at the first and second coupling regions, in response to applied control signals, thereby adjusting the insertion loss and dynamic range of the device. A sensor samples an output signal from the substrate and sends a signal to a controller, which controls the phase shifting devices and the heater strip to maintain the output signal within predetermined signal parameters. |
