Birefringence phase-matched direct third-harmonic generation in a ridge optical waveguide based on a KTiOPO<sub>4</sub> single crystal
نویسندگان
چکیده
Birefringence phase-matched third-harmonic generation at 1594 nm is performed for the first time in a KTiOPO 4 single crystal micrometric ridge waveguide. The energy conversion efficiency reaches 3.4% pump as low 2 µJ over pulse duration of 15 ps repetition rate 10 Hz. Strong agreements between theory and experiments both phase-matching obtained, which let us envision future triple photon quantum experiments.

Atomically phase-matched second-harmonic generation in a 2D crystal
Second-harmonic generation (SHG) has found extensive applications from hand-held laser pointers to spectroscopic and microscopic techniques. Recently, some cleavable van der Waals (vdW) crystals have shown SHG arising from a single atomic layer, where the SH light elucidated important information such as the grain boundaries and electronic structure in these ultra-thin materials. However, despi...
متن کاملDirect quasi-phase-matched fourth-harmonic generation.
We have theoretically demonstrated direct fourth-harmonic generation (FHG) based on a quasi-phase-matching (QPM) configuration in periodically poled lithium niobate. The wavelength dependence of period of FHG QPM gratings is calculated. Bandwidths of fundamental wavelength, temperature, and incident angle are also studied. We find a very wide bandwidth, as large as 115 nm, of fundamental wavele...
متن کاملSelf-Phase-Matched Second-Harmonic and White-Light Generation in a Biaxial Zinc Tungstate Single Crystal
Second-order nonlinear optical materials are used to generate new frequencies by exploiting second-harmonic generation (SHG), a phenomenon where a nonlinear material generates light at double the optical frequency of the input beam. Maximum SHG is achieved when the pump and the generated waves are in phase, for example through birefringence in uniaxial crystals. However, applying these material...
متن کاملThird harmonic generation from mid-IR to near-IR regions in a phase-matched silicon-silicon-nanocrystal hybrid plasmonic waveguide.
The conversion efficiency of third harmonic generation (THG) from mid-IR (3600 nm) to near-IR (1200 nm) regions in a silicon-silicon-nanocrystal hybrid plasmonic waveguide (SSHPW) was calculated. The required modal phase-matching condition (PMC) between the 0-th mode at fundamental wave (FW) and the 2-nd mode at third harmonic (TH) is achieved by carefully designing the waveguide geometry. Bene...
متن کاملPhase correction in double-pass quasi-phase-matched second-harmonic generation with a wedged crystal.
Compensation for dispersive elements is necessary for efficient multiple-pass and intracavity nonlinear frequency-conversion devices. We describe the use of a wedged quasi-phase-matched crystal to compensate for the phase shifts introduced by mirrors in such devices, taking advantage of the periodic variation in the relative phases of the interacting waves in a quasi-phase-matching grating. A r...
