Wavelength agile multiplexing

A multiplexing system comprising:

• a first multi-wavelength light emitter configured to emit a first multi-wavelength light output;
• a second multi-wavelength light emitter configured to emit a second multi-wavelength light output;
• a third multi-wavelength light emitter configured to emit a third multi-wavelength light output;
• a demultiplexer configured to receive and split the first multi-wavelength light output, the second multi-wavelength light output, and the third multi-wavelength light output into a plurality of unique outputs, wherein each of the first multi-wavelength light emitter, the second multi-wavelength light emitter, and the third multi-wavelength light emitter is directly connected to a different corresponding input of the demultiplexer;
• and
• a light combiner configured to combine the plurality of unique outputs into an output waveguide.

A method for multiplexing light, the method comprising:

• emitting a first light output from a first multi-wavelength light emitter;
• emitting a second light output from a second multi-wavelength light emitter;
• emitting a third light output from a third multi-wavelength light emitter;
• demultiplexing each of the first light output, the second light output, and the third light output, using a demultiplexer, into a plurality of unique outputs, wherein each of the first multi-wavelength light emitter, the second multi-wavelength light emitter, and the third multi-wavelength light emitter is directly connected to a different corresponding input of the demultiplexer;
• and
• multiplexing the plurality of unique outputs into an output waveguide using a multiplexer.
