From: Monolithic mode-selective few-mode multicore fiber multiplexers
Chip to FM-MCF interface performance. (a) The coupling losses between the FM-MCF multiplexer and the 4-core fiber butt-coupled to the end-face of the chip. (b) The mode extinction ratios for the FM-MCF multiplexer after a 10 m length of the 4-core fiber butt-coupled to the end-face of the chip. The values are given as averages across all four cores.
