ABSTRACT:
An optical output coupler having a reflector integrated in an evanescent coupler. In one aspect of the present invention, an apparatus according to an embodiment of the present invention includes first and second optical paths. An optical beam is to be directed through the first optical path. The apparatus also includes an evanescent coupler, which evanescently couples the first and second optical paths. The apparatus further includes a reflector, which is included in the evanescent coupler and integrated in the first and second optical paths. The optical beam that is directed through the first optical path is reflected from the reflector as the optical beam is concurrently evanescently coupled from the first to the second optical path.
