Abstract
Multiplane Light Conversion (MPLC) combines free-space propagation with spatial phase modulation to achieve complex spatial basis transformations. We have designed a Hermite-Gaussian (HG) mode multiplexer using the MPLC technique and investigated the impact of phase steps on insertion loss, mode dependent loss and mode purity. The experimental results show that the insertion loss of the HG-mode multiplexer is 0.3 dB, the mode dependent loss is 0.39 dB and the device generates HG-mode purity achieve to 93% when five-phase planes with a phase-plane spacing of 15 mm and 64-phase steps.
