英文摘要： The goals of project are to study and develop the resonance cavity enhanced emission plasmonic infrared emitters, and by the computer assisted optimization design, to fabricate and realize the thermal emitters which integrate Fabry-Perot resonance cavity and metal-dielectric structure with short period of hole arry. By building the theoretical model of coupling resonance between the plane wave-guide mode and surface plasmonic mode, it is expected that the effects of emitter dimension parameters on emission spectra can be explained. Furtherly, we hope to reveal the mechanism that the power from the spontaneous radiation with wide spectra are converted to high intensitive, high directional, narrow-band light by power drawing effect. In experiments, the micro-scals of hybrid optical films are fabricated by micro-electro-mechanical systems technology to realize the electrical modulation and manufacturability of emitter. The ultimate goal is to use the emitter in nondispersive isotope-selective infrared spectrophotometer based on 13-Carbon breath test for liver reserve function and liver cirrhosis.The test results will be used for assessment of emitter property.
