All-Optical Reshaping Based on a Passive Saturable Absorber Microcavity Device for Future 160-Gb/s Applications

A vertical-access passive all-optical switching gate has been used to regenerate the zero levels of a "...01010101..." 160-Gb/s bit pattern at 1561 nm. Autocorrelation function measurements show that an extinction up to 11.7 dB of the "ghost-pulses" can be achieved
