Abstract
A system that facilitates optical multiplexing and demultiplexing. The system includes an optical transmitter which is structured in the following way. A wavelength-splitting mechanism is coupled to the optical transmitter, which separates the wavelengths of light onto an array of input-optical-waveguide busses within the optical transmitter. An array of ring modulators within the optical transmitter is coupled to each optical-waveguide bus, wherein the input-end of a given ring modulator is coupled to a corresponding input-optical-waveguide bus. Output-optical-waveguide busses within the optical transmitter are coupled to the array of ring modulators, wherein the output-end of each ring modulator is coupled to a corresponding output-optical-waveguide bus. When a modulation signal is applied to a given ring modulator within the array of ring modulators, a specific wavelength of light is directed to the corresponding output-optical-waveguide bus.
