LETTER

We demonstrated optical filter characterization using optical frequency sweep with optical single sideband modulation technique, where the frequency shift range was 2GHz-10GHz. Undesired sidebands generated in the single sideband modulation due to electric phase errors can be compensated by automatic synchronized bias control. Fine pass band structures of a dual-section FBG were precisely measured, where the bandwidths of the pass bands were 440MHz.
