An increasing proportion of the world’s communications are carried by fiber optic cables. It has spread quietly, almost without being noticed into every situ- ation in which information is being transmitted whether it is within the home hi-fi system

Wavelength-selective directional couplers as ultrafast optical differentiators Abstract: Wavelength-selective directional couplers with dissimilar waveguides are designed for ultrafast optical differentiation within the femtosecond regime (corres

We propose and experimentally demonstrate an all-optical (all-fiber) temporal differentiator based on a simple π-phase-shifted fiber Bragg grating operated in reflection. The proposed device can calculate the first time derivative of the complex
