Costas Loop Experiments for a 10.6 µm Communications Receiver

We have transferred the principle of the Costas-type nonlinear phase-locked loop to the \lambda = 10.6 \mu m wavelength of CO 2 lasers. The ability of the optical Costas loop to regenerate the carrier of a binary phase-shift-keyed input signal and to perform coherent demodulation was demonstrated at...

Zusammenfassung:	We have transferred the principle of the Costas-type nonlinear phase-locked loop to the \lambda = 10.6 \mu m wavelength of CO 2 lasers. The ability of the optical Costas loop to regenerate the carrier of a binary phase-shift-keyed input signal and to perform coherent demodulation was demonstrated at a data rate of 20 Mbits/s.
