NOVELTY - The device has a single-element isotope-enriched polariton material sheet and a substrate on which the thin sheet of polarization excimer material is placed. The polarization excimer material is alpha-crystalline phase molybdenum oxide, alpha-crystalline phase vanadium oxide, h-crystalline phase boron nitride, silicon carbide, graphene and carbon nanotubes. The single element isotope type is 92Mo, 94Mo, 95Mo, 96Mo, 97Mo, 98Mo, or 100Mo, preferably, the Mo isotope type is 92Mo, 96Mo, or 100Mo. The thickness of the alpha-crystalline molybdenum oxide flakes is between 50-600nm, preferably, the thickness of the alpha-crystalline molybdenum oxide flakes is between 100-350nm . The substrate is a dielectric substrate, preferably, the substrate is a dielectric substrate that does not strongly absorb the mid-infrared laser, and further preferably, the substrate is an undoped monocrystalline silicon substrate. USE - Device for reducing optical loss of polarization excimer material based on isotope enrichment used in sub-diffraction focusing, biological sensing, nano imaging and super-prism field. ADVANTAGE - The device has high Q value nano micro-cavity, waveguide, coupler and other polarization excimer photonic device. The preparation technique of the device is simple, using conventional scattering near field scanning microscope to excite at room temperature, which is configured to generate long service life, low optical loss of phonon polarization element. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for reducing the optical loss of polarization excimer materials based on isotope enrichment. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the process for reducing the optical loss of a crystalline molybdenum oxide. (Drawing includes non-English language text)
