A hybrid pump wavelength assignment scheme for optical packet switch with parametric wavelength converters
This paper proposes a pump wavelength assignment scheme for an optical packet switch with parametric wavelength converters (PWCs) to reduce the number of different colored light sources while a predefined packet loss rate is satisfied. PWCs are separated into two sets. First set, each PWC has a different pump wavelength from each other. Second set, all PWCs have the same pump wavelength placed ...
متن کاملNoise-figure limit of fiber-optical parametric amplifiers and wavelength converters: experimental investigation.
Recent theoretical work predicts that the quantum-limited noise figure of a x(3)-based fiber-optical parametric amplifier operating as a phase-insensitive in-line amplifier or as a wavelength converter exceeds the standard 3-dB limit at high gain. The degradation of the noise figure is caused by the excess noise added by the unavoidable Raman gain and loss occurring at the signal and the conver...
متن کاملAn Optical Packet Switch based on Parametric Wavelength Converters
In an OPS, an optical fiber carries several wavelengths to transmit packets. An input fiber may carry as many packets as wavelengths that could be destined to one or several output fibers. The output contention occurs when multiple packets from different input fibers are destined to a single output fiber using the same wavelength at the same time. Only one packet is forwarded to the output fibe...
متن کاملWavelength Converters ∗
After a short introduction to the different requirements to and techniques for wavelength conversion, focus is on cross-gain and cross-phase modulation in SOA based converters. Aspects like jitter accumulation, regeneration and conversion to the same wavelength is discussed. It is predicted that jitter accumulation can be minimised while also assuring a high extinction ratio by using a 9–10 dB ...
متن کاملAn Architecture for a Wavelength-Interchanging Cross-Connect Utilizing Parametric Wavelength Converters
This paper proposes an architecture for a wavelength-interchanging cross-connect (WIXC) that can be used as a switching node of strictly transparent and scalable networks with all-optical routing and all-optical wavelength conversion capabilities. This architecture utilizes all-optical parametric wavelength converters based on difference-frequencygeneration (DFG) or four-wave mixing (FWM), alth...
