Abstract
A wavelength division multiplexer includes a prism, a collimator, and a filter group. The collimator injects an optical input signal into an input surface of the prism. The filter group is coupled to the prism. The filter group comprises a plurality of filters successively coupled to each other. Each filter reflects a different wavelength of the optical input signal and permits other wavelengths of the optical input signal to pass through to a next filter of the filter group.
Claims20
A wavelength division multiplexer, comprising:
- a prism comprising a prism input surface and a prism output surface, wherein the prism input surface comprises an input portion configured to receive an optical input signal, and wherein the prism output surface comprises an output portion configured to output a divided optical output signal comprising a plurality of wavelength optical signals spatially separated by a pitch;
- and
- a filter group coupled to a filter interface portion of the prism, wherein the filter group comprises a plurality of filters successively coupled to each other, wherein each filter reflects a different wavelength optical signal of the divided optical output signal and permits other wavelengths to pass through to a next filter of the plurality of filters.
