Monolithic Widely Tunable Packet Forwarding Chip in InP for All-Optical Label Switching

In this paper, we describe a monolithically integrated tunable optical packet forwarding chip in InP. The chip consists of a differential Mach-Zehnder Interferometer SOA tunable 40 Gbps wavelength converter integrated with an electro-refractive modulator for 10 Gbps label modulation. Error free performance and dynamic forwarding of asynchronous variable length packets is reported.
