| 英文摘要 | An optical multiplexer/demultiplexer is described. In this optical multiplexer/demultiplexer, multiple coupled-waveguide grating devices are optically coupled to a bus optical waveguide. A given coupled-waveguide grating device has a band-pass filter characteristic that encompasses multiple optical channels, thereby providing coarse optical filtering. Moreover, the optical multiplexer/demultiplexer includes multiple add/drop filters (such as ring resonators) that optically couple to the coupled-waveguide grating devices. A given add/drop filter has a filter bandwidth corresponding to a given optical channel, thereby providing fine optical filtering. Furthermore, the band-pass filter characteristic of the given coupled-waveguide grating device is approximately equal to or less than a free spectral range (FSR) of the given add/drop filter. |
