Abstract:
A configurable wavelength multiplexing device for use with incoming light at first and second wavelengths, the device comprising:first, second, and third reflectors; the first reflector, referred to as the configurable reflector, being disposed to intercept the incoming light traveling along an input path, the first reflector having a first state in which it transmits the incoming light along a first transmitted path and a second state in which it reflects the incoming light along a first reflected path; the second reflector being a wavelength-selective reflector that reflects light of the first wavelength and transmits light of the second wavelength; the third reflector reflecting at least light of the first wavelength; the first, second, and third reflectors being oriented so that when the incoming light is transmitted along the first transmitted path, the light of the first wavelength is reflected by the second and third reflectors to travel along second and third reflected paths, the third reflected path intersecting the first reflector at an angle such that the light of the first wavelength is transmitted by the first reflector and continues on the first reflected path; and the light of the second wavelength is transmitted by the second reflector along a second transmission path that is distinct from the first transmission path.
