Providing ondemand tunability to the photonic crystals would expand existing application areas and may enable new applications. Guided-mode resonance (GMR) is diffraction grating which shows sharp reflectance/transmittance response on narrow specific wavelength of the incident light. Flexible GMR devices are great vehicles to achieve high resolution high sensitivity strain sensor. This paper reviews thermally and mechanically tunable 2D photonic crystals and flexible GMR strain sensors.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128030833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use Continuous electrowetting (CEW) effect to drive the Galinstan droplet even at low voltage (-several V).

To tailor four IRMAs with different height between top and bottom metal layers, absorption resonance can be modified 2.07 pm and absorption intensity can be attenuated gradually. These characteristics of IRMA can be potentially used in variable optical attenuator (VOA). By changing the distance between top unit cells of four IRMAs, the resonances can be tuned in the range of 1.74 pm with an exponential relationship. All absorption intensities can be kept as higher than 90%.
