Integrated All-Optical Edge Enhancement Devices Fabricated by Femtosecond Laser Direct Writing Technique
We proposed and fabricated a compact three-layer device using femtosecond laser direct writing technique, integrating two lenses and a convolution kernel for optical convolution. By selecting a vortex kernel, we achieved direct edge extraction of the input patterns.
