In-Fiber All-Optical Fractional Differentiator Using an Asymmetrical Moiré Fiber Grating
In this work, it is demonstrated numerically that an asymmetric Moiré fiber grating operated in reflection can provide the required spectral response to implement an all-optical fractional differentiator. In our case, the accumulated phase shift is not associated with a point phase shift, as when wo...
