A novel optical header extraction scheme based on optical differential phase shift keying—DPSK—decoding is examined analytically and experimentally. The header is applied in front of the payload, on the phase of a pulsed optical level introduced for the duration of the header. The proposed scheme offers maximized header extraction efficiency, required by the electronics to identify the header b...

A photonic ATM switch based on wavelengthdivision multiplexing will include several lossy passive devices, erbium-doped fiber amplifiers, and semiconductor optical amplifiers (SOAs) in a cascade configuration for fast switching of ns order. Its level diagram, which is very different from those of optical transmission links, has not been adequately studied. This paper investigates the concept of...

This paper presents a new petabit photonic packet switch architecture, called PetaStar. Using a new multidimensional photonic multiplexing scheme that includes space, time, wavelength, and subcarrier domains, PetaStar is based on a three-stage Clos-network photonic switch fabric to provide scalable large-dimension switch interconnections with nanosecond reconfiguration speed. Packet buffering i...

We discuss how all-optical signal processing might play a role in future all-optical packet switched networks. We introduce a concept of optical packet switches that employ entirely all-optical signal processing technology. The optical packet switch is made out of three functional blocks: the optical header processing block, the optical memory block and the wavelength conversion block. The oper...

First, we will discuss the limitations and difficulties of MPλS, and we will address that the photonic packet switching will be an ultimate solution to solve the problems of MPλS. Next, we will focus on the OC-based photonic packet switching. The advantages of OC-based photonic packet switching include ultrafast photonic label processing capability, optical buffering using WDM fiber delay lines...

A novel optical packet switch with multiple ports is proposed, a buffer depth of thousands being possible. Its operation is verified by modeling and analysis.

We present experimental and numerical studies of a novel packet-switch architecture, the data vortex, designed for large-scale photonic interconnections. The selfrouting multihop packet switch efficiently scales to large port counts ( 10 k) while maintaining low latencies, a narrow latency distribution, and high throughput. To facilitate optical implementation, the data-vortex architecture empl...

This paper analyzes the packet loss and delay performance of an arrayed-waveguide-grating-based (AWG) optical packet switch developed within the EPSRC-funded project WASPNET (wavelength switched packet network). Two node designs are proposed based on feedback and feed-forward strategies, using sharing among multiple wavelengths to assist in contention resolution. The feedback configuration allo...
