Coherent optical multi-channel arrangement

摘要

A stabilization of the frequency spacing between the carrier frequency channels of the individual transmitters and the elimination of the risk of the channel crosstalk is obtained for an arbitrarily large number of transmitters in a coherent optical multi-channel arrangement which has a plurality of transmitters arranged in a group, a single coherent optical heterodyne arrangement for heterodyning a portion of the output of each of the transmitters with respective reference frequency lines and a control arrangement for controlling the channel carrier frequency of each of the transmitters by utilizing the heterodyne signal.
