Abstract(in English) | This report describes a phase-locked multi-carrier light generator that employs a CW light source, two phase modulators, and a dispersion medium. A sinusoidal phase modulation with a modulation index of π/4 and a group velocity dispersion of ±1/(4πf_m^2), where f_m is the modulation frequency, are applied to a CW light followed by a large sinusoidal phase modulation. This configuration provides a multi-carrier light with a flattened power spectrum for any modulation index of the 2nd phase modulation. By adopting a chirped fibre Bragg grating (FBG) as a dispersion medium instead of a long normal dispersion fibre, we can increase the stability of the optical output spectrum and reduce the size of the multi-carrier light generator. We have built a prototype with this configuration that generates a 61 carrier light with a 25 GHz interval and a power deviation of less than 8 dB. |
