Tunable optical add/drop multiplexer with multi-function optical amplifiers |
摘要 |
A photonic circuit includes a tunable drop filter arrangement that includes a plurality of resonators. The drop filter arrangement is tuned to remove a selected frequency from an input data stream from a waveguide. A wavelength sensor coupled to the drop filter to monitor the selected frequency to which the drop filter arrangement has been tuned. A tunable laser presents a new signal of a defined frequency indicative of a signal to be added to the input data stream. A modulator coupled to the tunable laser for receiving the new signal and forming a modulated signal. An add filter arrangement coupled to the modulator for receiving the modulated signal and adding the modulated signal to the data stream.
