Compact low-loss 8 × 8 silica optical switch based on large fan-in/fan-out couplers
{{output}}
An optical switch scheme based on large fan-in/fan-out multimode interference (MMI) couplers is proposed to enable compact, low-loss N × N switching with channel uniformity. Specifically, two identical 8 × 8 MMI couplers are connected via equal-path-length w... ...
