A Multi-channel free-space optical (FSO) communications system based on orbital angular momentum (OAM)-carrying beams is studied. We numerically analyze the effects of atmospheric turbulence on the system and find that turbulence induces attenuation and crosstalk among channels. Based on a model in which the constituent channels are binary symmetric and crosstalk is a Gaussian noise source, we ...

In this paper, we introduce a novel concept and design of full-duplex all-optical FSO transceiver evaluate its transmission performance in 200 m outdoor environment. Our enables reliable fiber-to-fiber link with intelligent lens-based optical-beam-stabilization (OBS) by utilizing miniaturized cost-effective 3-axis voice-coil motors (VCMs) actuators. The VCM-based moving lens that is widely used...

In this paper, performance evaluation of high speed optical wireless communication has been observed. It has been observed that Q value lies in the range of 26 to 15 dB and 25 to 14dB in the transmission power (8dBm) and attenuation (23dB) at distance of 800m to 2000m in free space optical communication. Similarly BER lies in the range of 10 to 10 4 and 10 to 10 in the transmission power and at...
