| Summary: | 碩士 === 國立交通大學 === 顯示科技研究所 === 103 === Engineered optical metamaterials present a unique platform for biosensing applications owing to their ability to confine light to nanoscale regions and to their spectral selectivity. Particularly, most recently the concept of Fano resonances was introduced to plasmonic metamaterials. An asymmetry Fano resonance gives rises to a very narrow resonance linewidth and hence increases the overall sensing figure of merit (FOM) for sensing applications. On the other hand, the organic/polymer based devices have advantages such as application flexibility and low cost. We combine the features of Fano resonance in plasmonic metamaterials and flexibility in flexible materials. In this thesis, we demonstrate a tunable fano resonance material fabricated on the polydimethylsiloxane (PDMS) substrate. With stretching the flexible substrate, the structural parameter will change, making the resonance wavelength be blue shift and improving sensing performance.
