Abstract:
1. An optical multiplexing and demultiplexing apparatus comprising: (a) an optical signal transmission block having on opposite first and second sides thereof corresponding parallel planar first and second surfaces substantially covered by respective highly reflective first and second coatings; (b) a first signal source comprising: (c) a second signal source comprising: (d) a multiplexed signal transmitting port on the second side of the transmission block, the transmitting port being positioned to receive transmitted signals from the first and second lenses emerging in mutual optical alignment as a multiplexed transmission signal from a multiplexed signal egress window in the second coating following reflections of the transmitted signals from the first and second lenses within the transmission block between the first and second coatings; and (e) a demultiplexer cooperative with the transmission block for separating a multiplexed reception signal into constituent received signals at respective first and the second reception wavelengths.
