New All-optical Wavelength Auto-router Based on Multibranch Waveguides

A new optical device for wavelength auto-router was proposed. Such a structure is useful in the integratedoptic for optical operation and data communication. We use the finite-difference beam propagation method to investigate the phenomenon of the proposed numerical model.

All-Optical Packet Router Based on Multi- Wavelength PPM Header Processing

The paper proposes an all-optical 1×M router architecture based on pulse-positionmodulation header processing (PPM-HP) scheme for packet routing in all-optical highspeed wavelength division multiplexing (WDM) packet switching network. The router is mainly comprised of all-optical clock extraction, pulse-position-modulation header extraction, continuous-wave (CW) sources, wavelength conversion m...

All-optical wavelength conversion based on time-domain holography.

All-optical wavelength conversion of a complex (amplitude and phase) optical signal is proposed based on an all-optical implementation of time-domain holography. The temporal holograms are generated through a cross-phase modulation (XPM) process in a highly-nonlinear optical fiber, avoiding the necessity of accomplish the phase matching condition between the involved pump and probe signals, and...

On Wavelength Translation in All-Optical Networks

Milan Kova cevi c and Anthony Acampora Department of Electrical Engineering Columbia University New York, NY 10027-6699 Abstract In this paper we study the bene ts of wavelength translation in all-optical networks providing clear channel circuit-switching among users. We rst establish approximate analytical models for a static-routing circuit-switched network with an arbitrary topology, both wi...
