A four-channel array of rf modulated laser signals was generated in a
LiNbO3 optical waveguide network by heterodyne mixing of two input lig
htwaves. Independent control of the rf phase in each channel wets prov
ided by integrated optical phase shifters. An optical frequency shifte
r was demonstrated to produce the required input signals. (C) 1997 Joh
