Optical Bistability in Kerr Fiber Bragg Grating
Santosh Pawar, Shubhada Kumbhaj, Pratima Sen and Pranay Kumar Sen
Reflective optical bistability in a Kerr fiber Bragg grating has been analysed by solving nonlinear coupled mode equations for a quasi-CW laser beam. The input-output characteristic of the reflected light from fiber Bragg grating exhibits hysteresis loop. It has been found that the width of the hysteresis loop and switching intensity are strongly dependent on the detuning wavelength of the incident light.
Keywords: fiber bragg grating, nonlinear coupled mode equations, optical bistability, optical switching and kerr nonlinearity.
