1/spl times/4 space switching and simultaneous all-optical wavelength conversion at 2,488 Gbit/s using a single monolithically integrated multiwavelength laser

摘要

A novel InGaAs/InGaAsP/InP integrated multiwavelength grating cavity laser is presented, which has been used to demonstrate space switching and simultaneous all-optical wavelength conversion at bit rates of 2.488 Gbit/s. This has been achieved using a single monolithically integrated device without the need for post-filtering to separate the converted signal from the input.
