摘要：
A single electroabsorption modulator (EAM) is utilized to perform subharmonic all-optical timing extraction from 160 Gb/s. The extraction technique is based on fast time-dependent loss saturation inside the EAM. The extracted timing is used for optical clock recovery with less than or equal to340 fs of timing jitter. The clock recovery technique is bit-rate flexible, and the bit-error-ratio measurements reveal an error-free operation with no receiver sensitivity penalty.
