Second Order Nonlinearity

The distributions of electric field and the induced second-order nonlinearity are discussed in a poling scheme where the width of a periodic electrode is shorter than the conventional coherent length. The theoretical aspects of quasi-phase matching for a subsequent experiment in second harmonic generation are analyzed. The present analysis consistently explains that the conversion efficiency can be enhanced if the electrode width is shortened, and maximized if the electrode width is optimized.

Second order nonlinear optical polarization P(2) has been calculated theoretically for several crystals having zinc-blende symmetries. Three distinct wavelengths 457 nm, 488 nm and 514 nm emitted from a continuous wave (cw) Ar-ion laser have been considered for the estimation of the second order nonlinear optical polarization. The study reveals nonlinear dependence of the second order nonlinear optical polarization on the applied electric field intensities at various wavelengths.
