Design of Silicon Integrated Bragg Gratings for Microwave Photonics Signal Processing

Abstract

This paper reviews the basic design flow of a silicon integrated Bragg grating (IBG) to achieve an arbitrary microwave photonics (MWP) signal processor. An example of using the design methodology to achieve a multichannel MWP Hilbert transformer (HT) based on a silicon IBG is given. Then, we review the adverse impact of apodization phase noise (APN) on the apodized grating response, and our recently demonstrated performance improvement of a grating-based MWP HT realized by compensating for the APN to correct the grating complex response. Finally, we give an outlook and suggestions for the future work.
