Hybrid bi-directional wavelength division multiplexing device |
摘要 |
An optical device simultaneously provides a multiplexing and demultiplexing function and combines dichroic WDM filter technology with Bragg grating filter technology. A plurality of adjacent sequential ports of a multi-port optical circulator serve as a vehicle for launching and receiving a multi-wavelength optical signal to be separated by the Bragg and dichroic filters. Other adjacent sequential ports having similar filters tuned to different wavelengths provide paths for combining the other wavelengths of light into a single signal. Conveniently a single circulating port serves as the input/output port of the device. The configuration can be applied an optical waveguide structure and, or more particularly to an optical fiber structure. Furthermore this configuration can combine multiplexing/demultiplexing function with a dispersion compensation function by adding a group of fiber Bragg gratings to a port of a circulator.
