Patent ID: 8325776

Claim:
A device for spreading optical light, the device comprising: a multi-transverse mode laser including a lasing cavity; a first end of the lasing cavity next to a high reflectivity dielectric reflector; a second end of the lasing cavity for emitting light; the first and second ends of the cavity lying in substantially parallel planes; the high-reflectivity dielectric reflector interposed between the lasing cavity first end and a plasmonic reflector; the plasmonic reflector for receiving light as incoming light and for emitting the light as exiting light; a reflective grating of the plasmonic reflector next to the high reflectivity dielectric reflector; the reflective grating for coupling the incoming light into a transverse plasmon wave; and, the reflective grating further for coupling the plasmon wave into the exiting light communicated through the cavity to the second end.
