The conventional method of quantifying optical nonlinearity is z-scan, which typically works with thin films, and thus acquires ensemble nonlinear responses, not from single nanostructure. Here we advocate an x-scan technique that is based on a confocal laser scanning microscope with both forward and backward detections, offering simultaneous quantification for nonlinear behavior of scattering, absorption and total attenuation from a single nanostructure.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126109368","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}

The full footprint of the system in three dimensions is only ~0.15 μm^3, which is just ~0.59 times of cubic wavelength. Strong optical scattering and dissipation of plasmonic resonance enable interaction with mechanical motion. We experimentally demonstrate the optical excitation and readout of the fundamental longitudinal mechanical oscillation, of which the real displacement is in the order of pico-meter. The plasmonic resonance with a wide spectral width allows the optical measurement of the mechanical oscillation signal over a large wavelength range (>100 nm) of the probe laser. Our dissipatively coupled plasmomechanical system shows not only tunability of the resonance frequency of mechanical oscillation but also the thermoelastic damping effect on the mechanical quality factor depending on the pump laser power.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133808043","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}

In this work we continue these explorations and demonstrate how a combination of a plasmonic Fano resonance and a Bragg reflector can contribute to the generation of narrowband visible colors. We demonstrate active tuning of these colors by stretching the array in the x- and y- directions and the reflector in z- to shift the colorimetric response of both elements. The combination of these two types of photonic structures allows for substantially increased flexibility in design and color-space tuning. Additionally, by fabricating these structures at scale, this methodology could prove useful towards the manufacture of agile metasurface color pixels","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128939000","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}

In certain species this includes a porous network with high precision lattices, strongly resembling photonic crystals produced using modern technological processes. Here we show two means for using these frustules as an optical material. Firstly, the unprocessed frustule can be used as a conventional photonic crystal. Secondly, a metal deposition processing step can yield plasmonic crystals. Both show high quality optical properties, analogous to lab-manufactured structures, and are produced over much larger areas at a much lower cost and without specialist equipment. Optical spectra (angularly resolved dispersions) are presented, along with simulation results to corroborate experimental findings and to allow optical mode characterisation and analysis.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124880151","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}
