Monolithically Integrated 40Gb/s Wavelength Converting Switch
01 January 2006
An all-optical wavelength-converting-switch module at 40Gb/s line rate is demonstrated in a fully integrated InP chip. The device combines a SOA-based wavelength converter and a fast-tunable multi-frequency laser. Sub-nanosecond switching among the 8 channels of the integrated laser is shown and error-free operation of the wavelength conversion process at 40Gb/s for each wavelength is demonstrated. The applications of fast switching wavelength conversion for optical switching and packet routing are discussed.
