Title:
METHOD FOR SWITCHING AND CONTROLLING SOLITONS IN TUNNEL-COUPLED OPTICAL WAVEGUIDES BY THE WEAK SIGNAL OF A DIFFERENT CARRIER FREQUENCY
Document Type and Number:
WIPO Patent Application WO/2004/068178
Kind Code:
A2
Abstract:
The invention relates to non-linear fibre and integrated optics, more specifically to fully optical switches and optical transistors and can be used for fibre-optical communication lines, integrated optical circuits etc. The inventive method consists in switching solitons in cubic non-linear tunnel-coupled optical waveguides (TCOW) by weak signal pulses or by the continuos radiation of a different carrier frequency. Said switching is carried out from one waveguide to another waveguide. Said invention makes it possible to convert (with a high amplification) a weak signal pulse modulation whose frequency does not correspond to a soliton-forming and soliton-propagating region and/or to fibre waveguide windows into a power soliton-sequence modulation on another required carrier frequency. In addition, a parasitic effect of short time and slow phase signal modifications and the influence of a phase of soliton input on a switching process are excluded.
