发明名称 DEVICE AND METHOD FOR GENERATING POLARIZATION-ENTANGLED PHOTON PAIR
摘要 <p>A wavelength-multiplexed polarization entangled photon pair generator (1) includes: a pump light source (2); a polarization entangled photon pair generating body (4) on which pump light (3) outputted from the pump light source (2) falls; and a spectrometer (7) on which a wavelength-multiplexed parametric photon pair (5) outputted from the polarization entangled photon pair generating body 4 falls. The polarization entangled photon pair generating body (4) made of a nonlinear optical crystal (11) generates wavelength-multiplexed photon pairs by subjecting the pump light 3 to type II phase matching. As a nonlinear optical crystal 11, lithium tantalate of periodically poled structure (11A) can be used, and as a spectrometer (7), an arrayed-waveguide grating can be used. Wavelength-multiplexed polarization entangled photon pairs (5) can thus be generated with simple equipment.</p>
