Cerenkov third-harmonic generation via cascaded χ^(2) processes in a periodic-poled LiTaO_3 waveguide

Abstract: We report a type of quasi-phase-matched (QPM) Cerenkov third-harmonic generation (CTHG) in a periodic-poled LiTaO₃ waveguide. The CTHG results from a guided-to-guided second-harmonic generation cascaded with a guided-to-radiated sum-frequency generation (SFG) in the waveguide. In the guided-to-radiated SFG process, nonlinear interactions with participating and nonparticipating reciprocal vectors would lead to different CTHG radiations. In addition, the power and temperature detuning characters of QPM CTHG were… Show more

“…Previous studies demonstrated that, under anomalous-like dispersion conditions, NCR can also be generated by modulating the phase velocity of the polarization wave [2]. NCR has been thoroughly researched in different nonlinear processes, such as second [3] and cascaded high-order harmonic generation [4][5][6], sum-frequency generation [7], and difference-frequency generation [8]. Such studies suggest potential applications to efficient frequency conversion [9], terahertz wave generation [10], ultrashort pulse-sharping [11], non-destructive domain-wall detection and imaging [12,13], and so on.…”

“…Although high-order harmonics (HH) are very important to the field of nonlinear optics, until recently, publications on HH generation using NPCs have been almost nonexistent. Recently, there have been several significant efforts to generate third harmonics in periodic, short-range ordered or radially poled NPCs, NPC waveguide and random quadratic media by NCD and NRND [14][15][16][17][18] . Also, high efficiency quasi-phase-matched harmonic generation from the 2nd to 8th order have been observed within a single LiNbO 3 (LN) NPC [19] .…”

“…In the previous works, we have reported that in dielectric waveguides with modulated 2ndorder nonlinearity (v (2) ), the reciprocal vectors provided by the structure can modulate the phase velocity of NPW. 19,20 The phase velocity could be decreased by the forward reciprocal vectors while be accelerated by the backward ones. In this letter, we designed a 2D rectangular periodically-poled LiTaO 3 (PPLT) crystal, which not only utilized the domain walls but also introduced v (2) modulations along the propagation direction of NPW…”
