Performance Analysis of Hybrid BPSK-MPPM Modulated Multicore Fiber Interconnect System

In this paper, spatially multiplexed hybrid binary phase shift keying-multi-pulse pulse position modulation (BPSK-MPPM) based 8-core multicore fiber (MCF) interconnect system is suggested for the foreseeable future exa-scale optical interconnect (OI) applications. The impact of different characteristic parameters like optical signal to noise ratio (OSNR), launch power, and inter-core crosstalk (XT) on bit error rate (BER) of hybrid BPSK-MPPM modulated OI system are discussed in detail. Further, error probability performance of conventional BPSK and hybrid modulation format are compared for 40 Gbps per channel. It is shown that the proposed hybrid scheme is suitable for futuristic data center, high-end computing system and silicon photonic transceiver chips.
