摘要

We report the implementation of an all-optical temporal differentiator based on an integrated phase-shifted Bragg grating (PSBG) in a compact single-mode silicon-on-insulator ridge waveguide. The integrated PSBG is designed to have a wide reflection notch by creating deep corrugations on the sidewalls of the ridge. The device is fabricated using a CMOS compatible process with 248-nm deep ultraviolet lithography. An experiment is performed. The use of the integrated PSBG for the implementation of an all-optical temporal differentiator is demonstrated.
