Thus far, these effects have been demonstrated at Thz to mid-IR frequencies, with the upper frequency limit set by limits of electron beam lithography, which can make graphene nanostructures as small as 15nm. In this talk, I will show that bottom-up block co-polymer lithography methods can create nanostructures with characteristic lengthscales as small as 12nm, and that in this regime the non-local interactions in graphene become strong, creating a significant blue shift of the plasmonic resonances. This allows for the creation of plasmonic cavities with resonances at wavelengths as short as 2.2um. The confinement factors of these cavities reach 135, which is exceedingly large, but less than what has been predicted by theory.","PeriodicalId":112265,"journal":{"name":"Active Photonic Platforms XIII","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133589565","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}

MoO3 is a layered material that exhibits both in and out-of-the-plane anisotropic polaritonic response at mid-IR wavelengths. We designed and experimentally demonstrated an anisotropic polaritonic absorber and showed that one can couple to all phonon modes and address them individually either using structural tunability or polarization control of incident infrared radiation. I will also discuss our experimental investigations of the birefringent optical properties of MoO3 in visible frequencies. By constructing MoO3 based Fabry-Perot resonator, we observed strong polarization-dependent tunability of the Fabry-Perot resonance due to different refractive index of MoO3 for different crystal directions.","PeriodicalId":112265,"journal":{"name":"Active Photonic Platforms XIII","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128336104","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 present a model, using our broadband refractive indices for xanthommatin, the chromatophore pigment, of the combined chromatophore and iridophore system, a dynamically tunable photonic device in Nature that responds across the visible-near-infrared. We also report on a broadband light-scattering sub-wavelength-periodicity metasurface composed of ferromagnetic islands. This magnetic metasurface is potentially rectifying. By applying a magnetic field, nonlinear optoelectronic properties such as light scattering and optical rectification can be reconfigured.

Eventually, heat is generated through a slower electron-phonon scattering process.
