Compensation of orbital-angular-momentum multiplexed communication system with wavefront correction
It was shown that the quality of free-space optical communication system using OAM(orbital angular momentum)multiplexing was inevitably degraded by AT(atmospheric turbulence).A wavefront phase correction based on Gerchberg-Saxton algorithm to mitigate the wave front phase distortion of the OAM-multi...

| description | It was shown that the quality of free-space optical communication system using OAM(orbital angular momentum)multiplexing was inevitably degraded by AT(atmospheric turbulence).A wavefront phase correction based on Gerchberg-Saxton algorithm to mitigate the wave front phase distortion of the OAM-multiplexed system transmitting through AT was proposed.The simulation results show that the crosstalk caused by AT decreases by using the proposed scheme.When the refractive index structure constant of AT <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <msubsup> <mi>C</mi> <mi>n</mi> <mn>2</mn> </msubsup> </math></inline-formula> is lower than<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mn>2</mn><mo>＆#x00D7;</mo><msup> <mn>10</mn> <mrow> <mo>＆#x2212;</mo><mn>15</mn></mrow> </msup> <msup> <mi>m</mi> <mrow> <mo>＆#x2212;</mo><mfrac> <mn>2</mn> <mn>3</mn> </mfrac> </mrow> </msup> </math></inline-formula> ,the BER(bit error rate)performance is decreased by two or three orders of magnitude with the proposed scheme. |
