Experimental Demonstration of a Narrow and Low-Divergence “Pin-Like” Beam in a 2-Gbit/s OOK FSO Link under Turbulence Effects when Using a Limited-Size Receiver Aperture

Abstract: We demonstrate a 2-Gbit/s FSO link using pin-like beam under emulated turbulence. With a 3-mm-diameter receiver aperture, the BER of the pin-like beam is below 1e-5 under all 100 random ...
