Abstract
In this work, an optical angular momentum (OAM) multiplexing enabled 400 Gbps free space optical communication (FSOC) system has been proposed using polarization division multiplexed (PDM) quadrature phase shift keying (QPSK) and digital signal processer (DSP) in the receiver. Different weather conditions such as clear weather, rain and fog are explored in proposed system and their deteriorating effects are observed in terms of log BER. Laguerre Gaussian (LG) beams (LG0,0, LG0,13, LG0,40, and LG0,80) are employed to realize four channel FSOC system and OAM multiplexing. Results revealed that integration of DSP in the PDM-QPSK receiver cause significant improvement in symbols placements in constellation and moreover proposed system successfully covered 3500 m, 3000 and 1200 m in FSO under clear weather, rain and fog, respectively.
