Abstract:
1. A two-optical signal generator comprising: a first light source for generating a single-mode optical signal, modulating the generated optical signal according to an inputted signal, and outputting a modulated optical signal including predetermined specific two optical signals having a predetermined optical frequency difference; a second light source for generating a multi-mode optical signal including predetermined two further optical signals having substantially the same wavelengths as those of the predetermined specific two optical signals of the modulated optical signal, respectively; and optical injection means for optically injecting the modulated optical signal outputted from said first light source into said second light source, and optically injecting the optical signal outputted from said second light source into said first light source, wherein the predetermined specific two optical signals of the modulated optical signal are injection-locked into the predetermined two further optical signals of the multi-mode optical signal, so that said second light source generates an injection-locked predetermined specific two optical signals.
