  ABSTRACT: Mid-infrared (mid-IR) signals can be converted to near-infrared (near-IR) wavelengths in As2S3-on-LiNbO3 waveguides by high efficiency four-wave mixing. It provided us a solution to detect mid-IR signals indirectly by state-of-the-art near-IR detectors. High efficiency four-wave mixing was demonstrated and electrical signal-to-noise ratio (eSNR) improvement was also investigated. Compared to direct detection by PbSe and HgCdTe (MCT) mid-IR detectors, the calculation indicated that, at room temperature, the indirect detection to mid-IR signals increased the electrical signal-to-noise ratio up to 67 dB.
