ABSTRACT:
An optical demultiplexer includes a first light bandpass filter that receives an input light beam at a first angle of incidence, passes a first light wavelength, and reflects a reflected beam, and a second light bandpass filter that receives the reflected beam at a second angle of incidence and passes a second light wavelength. A beam redirection element such as a reflective surface receives the reflected beam from the first light bandpass filter and redirects the reflected beam toward the second light bandpass filter at the second angle of incidence.
