Tapered Multi-Mode Interference Waveguide for High-Power Self-Organizing Single-Mode Semiconductor Laser Arrays


A 1 × N, tapered, multi-mode interference (MMI) coupler is numerically studied for use in a self-organizing semiconductor laser-array system. The MMI structure is linearly tapered in a way such that the single-port side is wider than the N-port side. The single-port waveguide is N times wider than the other ports to maintain intensity similar to that… (More)
