Abstract

We report the high-flux and broadband generation of biphotons with controlled frequency entanglement. For the generation of the entangled state consisting of frequency-anticorrelated photons, we use PPMgSLT pumped by a continuous-wave (cw) laser. Meanwhile, the state consisting of frequency-correlated photons is produced from PPKTP under the extended phase-matching condition. Both states exhibited interference patterns with over 90% visibilities in two-photon interference experiments.

Schematic drawing of our experimental apparatus for (a) measurement of frequency correlation and (b) two-photon interference in terms of the probabilistic generation of polarization entanglement. A modified polarization Michelson interferometer was used as a timing compensator. TBF; tunable bandpass filter, L, lens; PBS, polarizing beam splitter; NPBS, non-polarizing beam splitter; M, mirror; QWP, quarter-wave plate; SMF, single-mode fiber; APD, avalanche photodiode.

Fig. 2

Parametric emission spectra of (a) PPMgSLT and (b) PPKTP, obtained by conventional spectroscopy using a grating spectrometer followed by a linear-arrayed InGaAs detector. Upper (lower) graphs show the spectra of y- (z-) polarized photons, whose polarization is represented by E // y (z) in the graphs. Crystal temperatures were set at 41.3°C for the PPMgSLT and 31.5°C for the PPKTP.

Tuning curves of parametric emissions from PPMgSLT as a function of crystal temperature. The upper (lower) curve is the tuning curve for y- (z-) polarized emissions, indicated by E // y (z).

Measured coincidence counts as a function of pump power. Red (black) circles represent the counts of biphotons emitted from the PPMgSLT (PPKTP).

Fig. 6

Experimental results of two-photon interference in terms of the probabilistic generation of polarization entanglement. The data shown in (a) and (b) are the interference patterns as a function of the path-length difference (ΔL) of the modified polarization Michelson interferometer. The resultant interference fringes obtained from polarization correlation measurements are shown in (c) and (d). The graphs on the left (right) side represent the interference patterns of biphotons emitted from the PPMgSLT (PPKTP). Black (red) circles are the experimental data when θ 1 was set at + 45° (−45°).
