Novel Vertical-Cavity Surface-Emitting Lasers with Integrated Optical Beam Router for Massively Parallel Free-Space Interconnection

چکیده
We report a novel verticalcavity surface-emitting lasers (VCSEL) with monolithically integrated phaseshifters. Optical beams emitting at angles of 0" to 9.6" from the surface-normal direction have been achieved. Dynamic switching of the radiation angle has also been successfully demonstrated by tuming on/off the phase-shifted region of the VCSEL. This novel device can reduce the complexity and size of switching nodes, and increase reliability of the interconnect system. The high-density integration and wafer scale fabrication capability make them particularly attractive for massively parallel free-space optical interconnection.

An ultra-dense optical interconnection network is proposed for massively parallel processors. Using twodimensional arrays of beam-steering vertical cavity surface-emitting lasers (VCSEL) as space-division switching elements, a single-chip, free-space photonic banyan network (or other multi-stage networks) can be constructed. Our scheme does not require critical optical alignment and can be easi...
