All-fibre phase filters with 1-GHz resolution for high-speed passive optical logic processing
Authors present a fibre Bragg grating-based all-pass spectral phase filter with an unprecedented frequency resolution of 1 GHz, at least 10× improvement compared to a standard optical waveshaper. Using the all-fibre phase filter, fully passive NOT and XNOR logic operations are experimentally demonst...
