Mode-locked and noise analysis of hybrid soliton pulse source (HSPS) utilizing uniform fiber Bragg grating is described. The HSPS model is based on a time domain solution of coupled-mode equations including spontaneous emission noise. Relative intensity noise (RIN) is calculated using numerical solutions of these equations. It is found that near transform limited pulses are generated only a few frequencies even if system is properly mode-locked over a wide frequency range. Output pulse is not more affected at the fundamental mode-locking frequency because RIN has not a noise peak at this frequency. It is also found that RIN reduction is possible for mode-locked HSPS by selecting a suitable grating such as Gaussian apodized or linearly chirped.
