Ultrafast optical communications system with multiplexer and demultiplexer

摘要

The electronic-to-optical multiplexer takes n electronic inputs X_i where i=0 to n−1; converts X_i into optical signals Y_i each with a different wavelength; wavelength multiplexes Y_i; samples Y_i with an optical frame sync signal having a period of n*p seconds and a pulse width w; wavelength demultiplexes Y_i; staggers Y_i by i*p seconds; wavelength multiplexes Y_i; gates an optical clock signal with Y_i; and uses the gated optical clock signal as the optical output.;The optical-to-electronic demultiplexer takes n optical sources Z_i each with a different wavelength; wavelength multiplexes Z_i; gates Z_i with the input of the optical-to-electronic demultiplexer; wavelength demultiplexes Z_i; staggers Z_i by (n−i)*p seconds; wavelength multiplexes Z_i; gates Z_i with the frame sync signal delayed by (n−1)*p seconds; wavelength demultiplexes Z_i; detects Z_i with detectors DECT_i; and uses the output of DECT_i as the electronic outputs.
