Paper Abstract

Mode-locked and relative intensity noise (RIN) of hybrid soliton pulse source (HSPS) utilizing Gaussian apodized fiber Bragg grating (with zero dc-index change) is described. The HSPS is modeled by a time-domain solution of the coupled-mode equations including spontaneous emission noise. RIN is calculated using numerical solutions of these equations. It is found that for these gratings soliton type pulse are not generated at the mode-locking frequency. However, these pulses can be generated only at limited tuning range with and without noise. RIN peak does not locate at the fundamental frequency that shows optical resonance due to cavity roundtrip time. Also, obtained soliton pulses are not directly related to magnitude of noise.
