Abstract :
We have integrated an 850-nm vertical-cavity surface-emitting laser (VCSEL), its driver, and a diffractive lenslet array onto a single substrate to produce an integrated optoelectronic multichip module for signal fan-out and distribution. The diffractive element performs optical fan-out of the output beam from the VCSEL into an array of focused spots at a plane 1, 416 μm from the surface of the VCSEL. This corresponds to 160 μm from the surface of the diffractive lens. System design, fabrication, integration, and experimental characterization is presented.
