There was without doubt a 'Stephen Kerr effect
' in Stirling.
Sufficiently high powers can also change the fibre's refractive index through the Kerr effect
Two modalities were exhibited: the first when the pump beam induced a Kerr effect
in the MWCNTs-[Pt.sub.5] sample and the second when the pump beam excited the MWCNTs-[Pt.sub.30] film.
In practice, FWM and THG effects require phase-matching conditions that are typically of great difficulty to achieve in optical fibers ; therefore, Kerr effect
is typically included through the refractive index dependence on the electric field intensity, which is related with the SPM.
The optical Kerr effect
can be derived from different physical mechanisms of nonlinear refractive index.
The resonant wavelength of PhCRR depends on the refractive index of the rod material, radius (a) and dimensions of the core structure of resonant ring .The input power of optical waves induces the nonlinear effects in dielectric materials such as Kerr effect
"Our approach conditions the information before it is even sent, so the receiver is free of crosstalk caused by the Kerr effect
The same phenomenon takes place also due to the incoming field itself, in which case one speaks about the AC, or optical, Kerr effect
All-optical ultrafast photonic switches based on the nonlinear Kerr effect
in an optical waveguide draw particular attention toward high-bit-rate optical communication systems and ultrafast information processing .
Each term of the equation sequentially represents a linear attenuation, a dispersion of the first, the second and the third place value, the Kerr effect
, the stimulated Raman scattering and a change of the pulse slope .As we can see from the Schrodinger equation, the optical signal is changed by these effects classified as:
External EM fields affect light transmission in the optical fiber through electro-optic Kerr effect
and Faraday effect.
