“…In fact, some efficient SHG [18][19][20], sum-frequency generation (SFG) [21], and optical parametric oscillation (OPO) [22,23], notably thirdharmonic generation [24][25][26] in these materials have been reported. Recently, cascaded frequency conversion and signal tuning in these materials received much interest [27][28][29][30][31][32][33][34]. A quasi-phase matched (QPM) crystal composed of an unpoled lithium niobate (LN) dispersion section sandwiched between two periodically poled LN (PPLN) sections was constructed, in which amplitude modulation and frequency conversion can be obtained simultaneously by using the EO effect to control the relative phase among mixing waves [30].…”

We present here a possible high-flux photon-pair source constructed by single lithium niobate optical superlattice (OSL) with a combined quasi-periodically and periodically poled structure, which is from the principle of electrically induced parametric down conversion (PDC) after second-harmonic generation (SHG), predicted by the united theory developed in this paper, in which SHG, PDC and electro-optic (EO) effect are comparably treated as two-order nonlinear effects. In the OSL, the e-polarized fundamental frequency photons are first converted to double frequency ones with the same polarization; then the PDC process is triggered by EO effect when the fundamental frequency photons are almost exhausted; finally, the double frequency photons are converted again to a series of two-photon pair of fundamental wave. It is demonstrated that at 100 degrees C, in a 20.2mm long OSL with a 30V / mm applied electric field, a 100MW/cm(2), 1080 nm laser beam can be translated to a flux of high-purity two-photon pairs with a conversion efficiency close to 100%; and for a longer OSL the pump intensity can be further lowered. The device can also act as an ultra-low field electro-optic switch.

×Χ×We demonstrate here an optical triode from the principle of electrically induced quadratic cascading in single lithium niobate optical superlattice, predicted by the united theory of second-harmonic generation/parametric down conversion and electro-optic effect. In the optical superlattice, the e-polarized fundamental wave is first converted to double frequency one with the same polarization. At the “on” state, the PDC after SHG is triggered by a weak o-polarized fundamental wave (control wave) with the aid of applied electric field at the point where fundamental wave almost exhausted; finally, the double frequency wave is converted again to e-polarized fundamental one as high output. And when the control wave is absent, only the SHG takes place; fundamental output is at “off” state. The optical triode would have a response shorter than ps and a amplification ratio of 2*103
