Abstract
A wavelength-stabilizing method for use with an optical communication system capable of transmitting and receiving information by means of signal light between a pair of stations each having a coherent optical transmitter and a coherent optical receiver. This method is characterized in that each station transmits signal light while controlling its wavelength at the coherent optical transmitter and receives the incoming signal light together with the local light at a wavelength adjusted in accordance with the wavelength of the incoming signal light.
