title: Detailed analysis of a 40 GHz all-optical synchronization based on an amplified-feedback distributed feedback laser.
abstract: We demonstrate an all-optical synchronization using an amplified-feedback distributed feedback laser with coherent injection experimentally, which can synchronize 40 GHz degraded signals even with optical signal-to-noise ratio as low as 5 dB, or chromatic dispersion as large as 408 ps/nm. Besides, this optical synchronization has a large range of power operation, i.e. high sensitivity of synchronization, from -21.40 dBm to -8.23 dBm, as well as a large frequency-locking range of 190 MHz.
