Patent ID: 8606058

Claim:
A multi-channel optical coupler comprising: an elongate solid core mixer body having an input end, an output end and sidewalls forming a length of the mixer body, the input end configured for receiving at least one optical signal for transmission through the mixer body, wherein the length of the mixer body is substantially longer than a cross-sectional height and width of the solid core to diffuse the at least one optical signal transmitted through the mixer body to a uniform intensity across the output end; and a plurality of output tapers coupled to the output end, each of the plurality of output tapers including: a reception area adjacent the output end of the mixer body for receiving a portion of the at least one optical signal transmitted through the mixer body; and wherein a size of the reception area of a first output taper of the plurality of output tapers is different from a size of the reception area of a second output taper of the plurality of output tapers to vary the intensity of the optical signal received by the first output taper as compared with the second output taper.
