An ultra-rapid all-optical switch useful for application in the future high-bit-rate systems is presented. Ti:LiNbO3 waveguides are considered owing to the acceptable substrate nonlinear relative dielectric constant (a 41 01 8 m2/V2) and the consolidated waveguide fabrication technology. Logic gates which can perform the XOR AND and NOT functions are investigated. The optical switching is provided via optical control pulses in one or both arms by exploiting either the stable or the unstable region of the waveguided optical power versus the effective refractive index.

Abstract
An ultra-rapid all-optical switch useful for application in the future high-bit-rate systems is presented. Ti:LiNbO3 waveguides are considered owing to the acceptable substrate nonlinear relative dielectric constant (a 41 01 8 m2/V2) and the consolidated waveguide fabrication technology. Logic gates which can perform the XOR AND and NOT functions are investigated. The optical switching is provided via optical control pulses in one or both arms by exploiting either the stable or the unstable region of the waveguided optical power versus the effective refractive index.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
