Abstract
A solid core, multi-channel optical coupler comprising an elongate mixer body having an input end, an output end and sidewalls forming a length of the mixer body, where the input end is configured for coupling to a plurality of input channels providing an optical signal for transmission through the mixer body, and a plurality of output tapers coupled to the output end. Each of the output tapers has a reception area adjacent the output end of the mixer body for receiving a portion of the optical signal transmitted through the mixer body. Furthermore, the reception area of each output taper is variable to vary the intensity of the optical signal received by the output taper.
