DOI: 10.1364/ol.578129
Abstract: We develop a high-parametric-gain SU(1,1) interferometer based on an aperiodically poled potassium titanyl phosphate (apKTP) crystal, enabling frequency-domain low-coherence interferometry with undetected mid-infrared photons. The system achieves a signal-to-noise ratio as high as 40 dB and… read more here.
