碩士 === 國立交通大學 === 機械工程系所 === 103 === This thesis is attempted to study photonic crystal enhanced fluorescence (PCEF) with different polarizations and bandwidths. The PCs can form guided mode resonance for near field enhancement at a specific combination of wavelength and angle of incidence; hence, to achieve better sensitivity for fluorescence-based detection. The PCs fabricated in this work are nanostructures composed of a low refractive index dielectric coated with a high refractive index dielectric. Through controlling the thickness of the deposited low refractive index dielectric, SiO2, the resonance bandwidth can be controlled. The works achieved in this thesis includes: 1.Design and study the PCs’ geometries based on rigorous couple wave analysis (RCWA), 2.Fabrication of a large area PC by using replica molding and sputtering technique, 3.Evaluation of PCEF using commercial laser fluorescence scanner, 4.Testing the PCEF with various polarizations using angle resolved fluorescence set up, 5.Comparison the simulation with the experimental results from PC with various polarizations and bandwidths.
