Abstract

A photorefractive beamsplitter (PRBS) is introduced as an alternative to a polarizing beamsplitter (PBS) for coupling optical power into reflective modulators in a free-space optical interconnection (FSOI) system. The PRBS uses a single diffraction grating recorded in a photorefractive material to redirect the incident laser light into the first diffraction order and onto the modulators. Reflected interconnection light not matching the Bragg angle criteria transmits through the beamsplitter uncoupled. Experimental results show that the PRBS provides better uniform transmission for off-axis beams than the currently used PBS.
