Abstract

This study presents a Free Space Optical Communication system using InP-based integrated transceivers, demonstrating multichannel transmission capabilities. The system utilizes photonic integrated circuits (PICs) to achieve compact, energy-efficient transceivers suitable for scalable optical communication applications. Successful multi-channel data transmission at rates of up to 10 Gb/s was achieved in both indoor (2 m) and outdoor (up to 10 m) environments. The design incorporates distributed Bragg reflector (DBR) lasers, electro-absorption modulators, and arrayed waveguide grating (AWG) multiplexers. The system showcases high-quality transmission with low bit-error rates (BER ≤ 10⁻¹¹) and minimal power penalties.
