Study in Ammonium Dihydrogen Phosphate of Spontaneous Parametric Interaction Tunable from 4400 to 16 000 Å

Experimental studies in generation of high-purity photon-pairs using cascaded χ^(2) processes in a periodically poled LiNbO_3 ridge-waveguide device

“…The SPDC has been a well studied and common process in various χ 2 materials such as β-BaB 2 O 4 (BBO), KTiOPO 4 (KTP), LiNbO 3 crystals, and so on [2][3][4][5][6][7][8][9][10][11]. While the SPDC process is generally more effective in comparison with the SFWM process in pure χ 3 material, it often requires a more complicated optical coupling system than that of the SFWM-based system.…”

“…Parametric fluorescence by spontaneous parametric down conversion (SPDC) [1][2][3][4][5][6][7][8][9][10][11] and spontaneous four-wave mixing (SFWM) [12][13][14][15] is useful and realistic for such a photon-pair source, and it has been used in a lot of experimental studies concerning the QICTs.…”

Calculation characteristics of spontaneous parametric emission based on BaAlBO 3 F 2 crystal

“…Parametric fluorescence was first discussed in 1961 by Louisell et al [1] Since that time, comprehensive theoretical treatments have appeared [2][3][4] along with numerous experimental observations [2,[5][6][7][8] .…”

Millimeter-Wave Acoustic Transducers

“…27 In optics, the stimulated amplification of spontaneous decay products has long been understood. It was first demonstrated in visible light by Akhmanov et a/., 28 Magde and Mahr, 29 and Harris et a/.30,3i,32 j n t h e i ast experiment, for example, just by shining a high frequency beam onto a lithium niobate crystal the spontaneous decay products could actually be amplified up to where they were visible with the unaided eye. In the acoustic experiments, Foster and Putterman 27 showed that the process could go on in the higher nonlinearity of the helium until the input beam ("pump") is actually depleted by more than 30 dB.…”
