Proposal of a multiplex optical frequency comb generation system

A multiplex optical frequency comb generation system was proposed by using a waveguide type optical frequency comb generator. It was estimated that the maximum span of the multiplex optical frequency comb was 240 nm (=29 THz) which was limited by the index dispersion of the LiNbO/sub 3/ waveguide. Experimental results of the span as wide as 100 nm (=12 THz) were obtained by using five lasers around 1.5 /spl mu/m wavelength.
