Abstract
A wavelength-multiplexed polarization entangled photon pair generator () includes: a pump light source (); a polarization entangled photon pair generating body () on which pump light () outputted from the pump light source () falls; and a spectrometer () on which a wavelength-multiplexed parametric photon pair () outputted from the polarization entangled photon pair generating bodyfalls. The polarization entangled photon pair generating body () made of a nonlinear optical crystal () generates wavelength-multiplexed photon pairs by subjecting the pump lightto type II phase matching. As a nonlinear optical crystal, lithium tantalate of periodically poled structure (A) can be used, and as a spectrometer (), an arrayed-waveguide grating can be used. Wavelength-multiplexed polarization entangled photon pairs () can thus be generated with simple equipment.
