Summary:
This paper describes a muiti-carrier light generation technique that utilizes a CW light source, two phase modulators and a chirped fiber Bragg grating (FBG). By adopting a chirped FBG as a dispersion medium instead of a long normal dispersion fiber, we can increase the stability of the optical output spectrum and reduce the size of the muiti-carrier light generator. We have built a prototype of the multi-carrier light generator with this configuration. The prototype apply a 25 GHz sinusoidal phase modulation with a modulation index of π/4, and a dispersion with D = 98 ps/nm to a CW light followed by a 25 GHz sinusoidal phase modulation with a modulation index of 9.7π. We have obtained 61 carrier-light with the power deviation of less than 8 dB.
