We propose an effective scheme to enhance mid-infrared dispersive wave (DW) emission by utilizing dispersion engineering of the waveguide and a weak continuous wave (CW) trigger. The scheme enables better coherence and higher signal-to-noise ratio in dispersion-engineered lithium niobate (LiNbO3) waveguides, allowing for mid-infrared emission at around 3 μm with sufficient power level. This emission is feasible for multi-species greenhouse gas detection through gas absorption spectroscopy.
We propose an effective scheme to enhance mid-infrared dispersive wave (DW) emission, which includes disper-sion engineering of the waveguide and the assistance of a CW trigger. Our suggested approach can help achieve better coherence and higher signal-to-noise ratio by adding a weak CW trigger with the femtosecond pulse pump in dispersion engineered lithium niobate (LiNbO3) waveguides. First, the integrated dispersion profile of LiNbO3 waveguides is designed based on dispersion engineering regarding the sidewall angle and slab thickness. Second, with the assistance of a weak CW trigger, the mid-infrared DW is enabled or further enhanced. The optimal CW-triggered wavelength and operating conditions are ascertained. Mid-infrared emission at around 3 mu m with a sufficient power level is accessible after optimization, which is feasible for multi-species greenhouse gas detection through gas absorption spectroscopy.(c) 2023 Optica Publishing Group
