Abstract

In this work, a 2 2 spatial modes 10 Gbps (40 Gbps) inter-satellite optical wireless communication (IsOWC) link has been proposed incorporating hybrid wavelength division multiplexing (WDM) and mode division multiplexing (MDM) techniques. The proposed link employs 2 distinct Hermite Gaussian (HG) spatial modes of 2 distinct wavelength channels (850 nm and 850.8 nm) to achieve a net data transmission rate of 40 Gbps. The link performance has been compared for non-return-to-zero (NRZ), return-to-zero (RZ), and alternate mark inversion (AMI) schemes. The proposed link demonstrates reliable transmission along 5000 km inter-satellite link with acceptable performance.
