Abstract
An optical device comprising an optical element optically coupled with at least two lenses, each lens having at least a substantially collimating end, the at least substantially collimating ends being inwardly facing one another and each lens having a substantially focusing end, the substantially focusing ends being outwardly facing, and at least one waveguide disposed adjacent and spaced from the each outwardly facing end for coupling light to or from an adjacent lens, the waveguides each having an end that is separated from its adjacent lens by an optical distance of approximately d1, an optical distance between the two collimating end faces of the at least two lenses being d2, where d1 is approximately equal to one half d2.

An optical device comprising:
- two lenses, each lens having an at least substantially collimating end face and a substantially focusing end face;
- an optical element coupled with at least one of the two lenses;
- a waveguide adjacent at least each of the two lenses for launching light to or from a respective adjacent lens, the waveguides each having an end that is separated from its adjacent lens by an optical distance of approximately d.sub.1, an optical distance between the two substantially collimating end faces of the at least two lenses being d2, where d.sub.1 is approximately equal to one half of d.sub.2, and wherein d.sub.1 >0.
