Beam directing device |
摘要 |
Described are various optical devices having at least two optical waveguides for inputting and outputting optical beams coupled thereto by a single collimating lens. Located proximate to the lens is a polarization dependent beam directing device that deflects orthogonally polarized optical beams in opposite directions by a first and second angle, respectively, when the beams are propagating in the same direction. The polarization dependent beam director compensates for an angle between a first beam input via a first of the two waveguides and a second beam input via a second of the two waveguides. The polarization dependent beam director also deflects a first beam propagating towards the waveguides in a first direction so that it is output via the first of the two waveguides and deflects a second beam propagating towards the waveguides in a second direction opposite the first so that it is output via the second of the two waveguides. Disclosed are three and four port interleavers and a four port circulator.
