	Kitaeva GK, Kornienko VV, Kuznetsov KA, Pentin IV, Smirnov KV, Vakhtomin YB. Direct detection of the idler THz radiation generated by spontaneous parametric down-conversion. Opt Lett. 2019;44(5):1198–201. Abstract: We study parametric down-conversion (PDC) of optical laser radiation in the strongly frequency non-degenerate regime which is promising for the generation of quantum-correlated pairs of extremely different spectral ranges, the optical and the terahertz (THz) ones. The possibility to detect tenuous THz-frequency photon fluxes generated under low-gain spontaneous PDC is demonstrated using a hot electron bolometer. Then experimental dependences of the THz radiation power on the detection angle and on the pump intensity are analyzed.

	Kuznetsov KA, Kornienko VV, Vakhtomin YB, Pentin IV, Smirnov KV, Kitaeva GK. Generation and detection of optical-terahertz biphotons via spontaneous parametric downconversion. In: Proc. ICLO.; 2018. 303. Abstract: We study spontaneous parametric downconversion (SPDC) in the strongly non-degenerate regime when the idler wave hits the terahertz range. By using the hot-electron bolometer, for the first time the SPDC-generated idler-wave photons were directly detected in the terahertz frequency range. Spectrum of corresponding signal photons was measured using standard technique by the CCD camera. Possible applications of correlated optical-terahertz biphotons are discussed.
