Abstract:
Provided are a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, and more particularly, a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, in which a phase shift value due to atmospheric turbulence is obtained from reflected light of transmission light generated from a femtosecond laser optical comb and the transmission light is pre-distorted on the basis of the phase shift value, thereby pre-compensating, in a transmission end, for phase noise due to atmospheric turbulence.

Claim (Index 7):
The device of  claim 1 , wherein the second laser light is configured by overlapping two or more cw lasers having different optical frequencies, and\n the modulation method is a method of independently modulating each of the cw laser configuring the second laser light with one selected from phase modulation (PM), frequency modulation (FM), phase-shift keying (PSK), frequency-shift keying (FSK), quadrature phase shift keying (QPSK), and quadrature amplitude modulation (QAM).
