Patent ID: 7646949

Claim:
An optical device, comprising: a waveguide immobilized on a base and terminating at a facet, the waveguide guiding light signals such that they exit the waveguide through the facet, upon the light signals being incident on the facet the light signals traveling in a direction that is parallel to a direction of propagation of light signals in the waveguide; a port configured to receive the light signals from the waveguide such that the light signals travel through the port, the light signals entering the port traveling in a first direction and the port being configured to change the direction of the light signals from the first direction to a second direction that is toward a location above the device or below the device; and a wedge configured to receive light signals from the port such that the light signals travel through the wedge and then exit the wedge traveling in a third direction, the wedge being configured to change the direction that the light signals travel from the second direction to the third direction, the third direction being toward a location above or below the device and at an angle in a range of 88° to 92° relative to the device.
