Abstract:
A multi-port optical device comprising:a first lens having at least two substantially linear arrays of at least 4 ports each at an end face thereof;a second lens disposed in optical alignment with the first lens and having at least 4 ports forming at least a third linear array, the third array of 4 ports being optically aligned with at least some of ports at the end face of first lens; and, an optical element interposed between the lenses for obtaining a desired function, wherein a first line intersecting each of the at least 4 ports of a first of the at least two linear arrays is parallel to a second line intersecting each of the at least 4 ports of each of second of the linear arrays, and wherein the first line and the second line are parallel to and spaced from a line intersecting the optical axis of the lens at its end face.
