Abstract

Using Space-Division Multiplexing (SDM) through multicore optical fibers (MCFs) can significantly increase the transmission capacity. However, compatibility with silicon photonics, a promising technology for compact, low-cost and power-efficient devices, requires integration between the two platforms. Using uniform grating couplers combined with compact tapers, two arrays-for 0 degrees and 10 degrees-were designed, fabricated and experimentally characterized. Simulations indicate coupling efficiencies of -4.64 dB and -3.64 dB for the 0 degrees and 10 degrees couplers, respectively, with bandwidths of 66.5nm and 127.3nm. Experimental results yielded efficiencies of for both designs, and corresponding bandwidths of 46.8nm and 90nm. (AU)
