چکیده
Ferroelectric crystals are important materials in many kinds of applications. Since the invention of so called quasi-phase matching technique, periodically domain-inverted ferroelectrics crystals with modulated second order nonlinear susceptibility are widely used in frequency conversion application. In periodically domain-inverted ferroelectrics crystals, besides the nonlinear optical coefficients, other third-rank tensors, such as the electro-optic (EO) coefficient, are also modulated periodically because of the periodically reversed ferroelectric domains. This periodically modulation of the EO coefficient also brings some novel applications. In this paper, tunable wavelength converter and filter are investigated based on periodically poled lithium niobate are investigated.

Šolc-type wavelength filters based on TE↔TM mode conversion utilizing periodically poled Ti-diffused lithium-niobate channel waveguides
We have demonstrated the Šolc-type wavelength filters in a 52mm long periodically poled Ti diffused lithium niobate channel waveguide which has a domain period of 16.6μm. At room temperature, the center wavelength and the full-width at half maximum of the filter were about 1272.49nm and 0.23nm, respectively. The nearest side-lobe is about 7dB.

Ferroelectric crystals are important materials in many kinds of applications. Since the invention of so called quasi-phase matching technique, periodically domain-inverted ferroelectrics crystals with modulated second order nonlinear susceptibility has received much attention owing to its outstanding nonlinear optical properties(Magel et al.,1990; Xu et al.,1993; Zheng et al.,1998). In periodic...
متن کاملElectromagnetically induced transparency-like transmission in periodically poled lithium niobate with a defect.
Electromagnetically induced transparency (EIT)-like transmission is observed in an electro-optic (EO) tunable periodically poled lithium niobate (PPLN) with a central defect. When an electric field is applied, light satisfying the phase matching condition keeps its original polarization, although it experiences polarization rotation then turns back. Therefore the corresponding light always may ...
متن کاملTunable terahertz-wave generation from DAST crystal by dual signal-wave parametric oscillation of periodically poled lithium niobate.
The first known demonstration of tunable terahertz-wave generation by difference-frequency generation of dual signal-wave quasi-phase-matched optical parametric oscillation was performed with periodically poled LiNbO(3) (PPLN) with a series of gratings. An organic ionic salt, 4-dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST), was used as a nonlinear crystal. A compact terahertz-wave sourc...
متن کاملOptical phase erasure and its application to format conversion through cascaded second-order processes in periodically poled lithium niobate.
We describe a new optical phase erasure characteristic of periodically poled lithium niobate (PPLN) by using cascaded second-harmonic generation and difference-frequency generation with the signal set at the quasi-phase-matching wavelength. A simple analytical expression is derived clearly explaining the operation principle. It is interesting that the optical phase erasure feature enables an al...
