Abstract:
An optical coupling arrangement comprising:a first substantially collimating lens, having an input port at an input end face, and a substantially collimating output end face;a second substantially collimating lens, having a substantially collimating input end face and an output end face having an output port, wherein the output end face of the first substantially collimating lens is in-line and spaced from the input end face of the second substantially collimating lens;a first longitudinal optical waveguide having a longitudinal optical axis optically coupled to the input port at the first end face; and,a second optical waveguide having a longitudinal optical axis optically coupled to the output port of the second substantially collimating lens, wherein the longitudinal optical axis of the second optical waveguide and the longitudinal optical axis of the first optical waveguide are not parallel.
