Nonlinear optical signal processing Nonlinear optics devices
2015/5/25
We demonstrate error-free, no power penalty, all-optical XOR operation for 40 Gbit/s phase-encoded signals in a highly-nonlinear photonic chip. This scheme exploits the Kerr nonlinearity in a dispersi...
All-Optical XOR Gate with Feedback using Highly Ge-Doped Nonlinear Fiber
Optical logic devices Nonlinear optics fibers Highly Ge-doped nonlinear fiber
2015/6/10
We demonstrate an all-optical XOR gate with feedback using cross-polarization-rotation in a highly Ge-doped-nonlinear fiber. The optical feedback employs a TOAD to clean up signal and for wavelength c...
