Abstract
We propose a simple optical preprocessing for optical clock recovery using a fiber Bragg grating (FBG) filter. In the proposed scheme, the signal preprocessing is performed by suppressing the carrier component through the FBG filter, and experiment shows that the clock component is larger than about 10 dB compared with other rf components within a distance of ± 3 GHz from the clock frequency component.
