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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generator of polarization entangled photon pairs and method of generating the same","description":"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 ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488231","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
