“…Another recently developed switching technique involves electrooptical beam deflection in combination with an optical phasar [13]. This technique requires very complex electrical, mechanical, and optical engineering of the fabric, especially for large port counts, and the reliability and scalability are still open issues.…”

Next-generation switches and routers may rely on optical switch fabrics to overcome scalability problems that arise in sizing traditional electrical backplanes into the terabit regime. In this paper, we present and discuss several optical switch fabric technologies. We describe a promising approach based on arrayed waveguide gratings and fast wavelength tuning and explain the challenges with respect to technical and commercial viability. Finally, we demonstrate an optical switch fabric capable of 1.2-Tb/s throughput and show packet switching with four ports running at 40 Gb/s each.

“…Another switching technique has been recently presented using Electro-optical beam deflection in combination with an optical phasar [23]. This technique of electro-optical beam deflection in front of an array of waveguides (phasar) requires very complex electrical, mechanical and optical engineering of the fabric, especially for large port counts, and seems to be more challenging than using beam deflection by fast wavelength selection in front of AWG routers as described in the next section.…”

Current IP/ATM routers use an electrical switching fabric/backplane and either optical or electrical interconnects between the line cards to route data. An electrical backplane and associated connectors limit the number of high speed interconnections due to practical considerations. Scaling these so-called third generation routers to the terabit regime with high port densities faces enormous problems due to the high interconnect and electrical power density. Packet routers with an optical switching fabric are considered as the next generation of IP/ATM Multi-Service routers which enable scalability towards the Terabit and Petabit regime. In this paper, various architectures with electrically active or passive optical switch fabrics will be highlighted and differences in terms of switching speed and scalability will be discussed. Recent results using a passive Array Waveguide Grating (AWG) router and fast wavelength tunable laser are presented in the second half of this paper.
