Intensity noise of mode-locked fiber grating lasers

摘要

Intensity noise of mode-locked hybrid soliton pulse source (HSPS) with linearly chirped uniform fiber Bragg grating (FBG) is reported using by coupled-mode equations. Mode-locking is difficult to achieve for some value of rf and dc bias currents because of increasing noise. Hence, transform-limited pulses are not generated over a wide tuning range although these pulses are obtained over a wide tuning range without any noise.
