160-Gb/s Optical Time-Division Demultiplexing Using a Mach–Zehnder Modulator in a Fiber Loop
Optical switching a 160-Gb/s signal using a LiNbO Mach-Zehnder modulator (MZM) is enabled by a novel method of connecting it within an optical fiber-loop mirror. The principle of operation exploits the unidirectional optical modulation of the MZM such that counterpropagating waves within the loop experience unequal amplitude modulation leading to output transmission of a high-quality 40-GHz pulse ...Show More

Electrooptic phase modulation of stretched 250-fs pulses for suppression of third-order fiber dispersion in transmission
Optical pulse distortion due to third-order dispersion (TOD) in linear fiber transmission of 250-fs pulses at 5 GHz over 600 m is reduced by applying electrooptic phase modulation (EOPM) from a LiNbO/sub 3/ device. Initial propagation in dispersion-compensating fiber cancels the second-order dispersion of the fiber-link and also linearly chirps the pulses to a stretched width of 47 ps, which enabl...Show More
