“…Therefore, the picosecond pulse width and the wavelength tuning capability make this model a candidate source for multiwavelength OTDM communications systems [10]. However, recently, many new profiles and structures of fiber gratings have been proposed and demonstrated to achieve wider bandwidth and high bandwidth utilization in dispersion compensators [14,15] and bandpass filters [16][17][18]. A new kind of grating profile with sinusoidal chirps of grating periods was introduced by Zhang et al to improve their performance as dispersion compensators and multichannel filters [19][20][21].…”

In this study, a mode-locked hybrid soliton pulse source (HSPS) utilizing sinusoidal chirped fiber Bragg grating (FBG) is reported for the first time, using the time-domain solution of coupled wave equations and rate equations. The sinusoidal chirped FBG provides a wider bandwidth by adjusting the reversion coefficient or chirp rate even if the FBG length is short. Numerical results also indicate that an HSPS-utilized sinusoidal chirped FBG produces shorter pulses in the 25 − 72 ps range, whereas the pulses range from 31 to 97 ps for a linearly chirped tanh apodized grating, and from 30 to 80 ps for a linearly chirped Gaussian apodized grating, along with an increase in the modelocking frequency range.
