In this paper, we propose an analytical model to evaluate the power consumption in the switching fabric of a bufferless shared-per-wavelength (SPW) optical packet switch architecture in which one bank of wavelength converters (WC) is dedicated to each wavelength. We assume that both optical gates and WCs are realized in semiconductor optical amplifier technology. In our evaluation, we account for...
In this paper, a novel approach based on Semiconductor Optical Amplifier Mach-Zehnder interferometer (SOA-MZI) for extracting the bit-serial header from optical packet is proposed Numerical analysis and simulation show that more than 15 dB contrast ratio of the separated header at 2.5 Gbit/s to the suppressed payload at 40 Gbit/s achieved. In addition, the SOA-MZI parameters are discussed and designed...
To provide contention resolution and QoS management while allowing controllable delaying of optical traffics, we effectively designed a node architecture suitable for optical packet and burst switching. The proposed architecture is based on a set of novel traffic engineering protocols providing QoS guarantees and allowing burst transmission, admission control, contention resolution, and real-time...
We report on the latest advances in photonic integration of functions required for optical routing and switching in the LASOR project including wavelength conversion, packet forwarding, optical buffers, optical synchronizers, optical clock recovery and mode-locked lasers.
We present a performance model for fiber delay line (FDL) buffers having access to multiple wavelengths on an output fiber. In optical burst switching and optical packet switching, contending bursts (or packets) need to be dealt with in an effective way, and both wavelength conversion and optical buffering are viable solutions. The buffer studied here includes both solutions, with full wavelength...
Transparent optical multicast by multi-wavelength conversion has revealed a brand-new way for performing data multicast function directly in the optical domain without bypassing any electronic processing. Wavelength conversion by four-wave-mixing (FWM) is suitable for high-bitrate data transmission and offers strict transparency to any modulation format. In this paper, experimental results of performance...
Wavelength conversion has been acknowledged as one of the most significant optical processing functions and various papers have been involved with investigating methods of translating very high bit-rate data into other wavelengths. This paper will give an overview of the recent advances in the area, with emphasis on methods that can be used as both wavelength and waveband converters, which can be...
