Comparative Test of Two Methods of Quantum Efficiency Absolute Measurement Based on Squeezed Vacuum Direct Detection
I. N. Agafonov, M. V. Chekhova, T. Sh. Iskhakov +3
We realize and test in experiment a method recently proposed for measuring absolute quantum efficiency of analog photodetectors. Similarly to the traditional (Klyshko) method of ab…
Biphoton compression in standard optical fiber: exact numerical calculation
G. brida, M. V. Chekhova, I. P. Degiovanni +4
Generation of two-photon wavepackets, produced by spontaneous parametric down conversion in crystals with linearly chirped quasi-phase matching grating, is analyzed. Although being…
Chirped Biphotons and Their Compression in Optical Fibres
M. V. Chekhova, G. Kh. Kitaeva, O. A. Shumilkina +3
We show that broadband biphoton wavepackets produced via Spontaneous Parametric Down-Conversion (SPDC) in crystals with linearly aperiodic poling can be easily compressed in time u…
