Performance analysis of photonic lantern based coherent receivers

In this paper, we present the simulation results for bit-error-rate improvements of photonic lantern based coherent LIDAR systems. Our results show that using a 19-port photonic lantern, the bit-error-rate can be improved to 0.06 from 0.30 for a range of 100 meters, corresponds to a detection rate improvement from 70% to 94%.
