✦ Synopsis

In this work, we demonstrate a reliable all-optical technique for performing optical double sideband (ODSB) to single sideband (OSSB) format conversion of a 40 Gb/s non-return-to-zero signal. It is based on the optimization of a detuned optical filter, which was implemented on a fiber Bragg grating (FBG) with a complex apodization profile. An OSSB signal with negligible distortion was obtained, as the FBG presented a nearly ideal frequency response. Higher tolerance to chromatic dispersion enabled by the OSSB signal in comparison to the ODSB signal was demonstrated on both simulation and experimental results.

## Abstract A novel all‐optical technique for microwave generation using photonic crystal fiber Brillouin laser is presented, and a 9.78‐GHz microwave signal generator based on the Brillouin laser is experimentally realized. The Brillouin laser is based on a fiber Fabry‐Perot cavity with fiber Brag
