Abstract :
A novel design of THz-bandwidth all-optical arbitrary-order differentiators based on phase-shifted long period fiber/waveguide gratings is proposed and numerically demonstrated. This solution offers a dramatically increased tolerance against practical variations in the grating parameters (e.g. coupling strength).
