Abstract
A multi-channel, multi-port bi-directional optical tap coupler with an alignment base element, a pair of sub-assemblies located at opposite ends of the alignment base element, focusing elements located next to each sub-assembly, and an optical filter adjacent to, and in-between the focusing elements is described. The first sub-assembly has an array of waveguides with each waveguide having a radial offset and an azimuthal position with respect to a center axis of the array. The first array includes transmission waveguides and receiving waveguides and each receiving waveguide has a corresponding transmission wave guide that is separated by an azimuthal angle of 180 degrees. The second sub-assembly has a second array of waveguides including a wave guide having the same radial offset and the same azimuthal position for each of the transmission wave and receiving guides of the first array.
