WebPeriodically poled lithium niobate (PPLN) waveguides are a powerful platform for efficient wavelength conversion. Conventional PPLN converters, however, typically require long device lengths and high pump powers due to the limited nonlinear interaction strength. Here we use a nanostructured PPLN waveguide to demonstrate an ultrahigh normalized ... WebWe produce periodically-poled lithium niobate (PPLN) jin two forms: as a bulk crystal with a thickness of up to 1 mm, and as a waveguide device. Bulk PPLN crystals are tailored for the production of tunable mid-infrared radiation through pumping by commonly-available …
WebPeriodically poled lithium niobate (PPLN) has become the nonlinear-optical material of choice in many infrared optical parametric oscillators (OPO’s) due to its high nonlinearity, readily engineered tuning characteristics, and repeatable fabrication. The domain periods required for these OPO’s are typically between 15 µm and 30 µm, and WebIntroduction . Based on the quasi-phase matching theory (QPM), the nonlinear optical crystal Lithium Niobate is made into a periodically inverted domain structure, called Periodically Poled Lithium Niobate (PPLN), to compensate for phase mismatch caused by dispersion, so that the effective nonlinear coefficient of the nonlinear optical crystal can be used to the …

WebDec 17, 2024 · Abstract. We present a study of noncritical phasematching behavior in thin-film, periodically poled lithium niobate (PPLN) waveguides. Noncritical phasematching refers to designing waveguides so that the phasematching is insensitive to variations in waveguide thickness, width, or other parameters. For waveguide thickness (the dimension …
