As these fields merge, metal optoelectronics using hot carrier effects may pave the way for new device architectures with improved flexibility, frequency response, and ultrafast time-dynamics. In this presentation, we will discuss our recent work building hot electron photodetectors for NIR detection using Si and metal oxides, improved response using nanoscale metal alloys, and time-resolved ultrafast detection via pump-probe techniques exploiting surface plasmon excitation. Further, we will show how the incorporation of index near zero (INZ) substrates can lead to nearly 100% absorption in thin metal films, providing a new platform for hot electron devices. We will conclude with an outlook and discuss future possibilities with these novel material systems.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"32 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":"124517927","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 the strong coupling regime, the hybridization of the emitters with surface plasmons generates spatially extended coherent states called polaritons. These states span over a coherence length of several microns. We show how fluorescent quantum dots weakly coupled to a surface plasmon interact with J-aggregated organic molecules strongly coupled with a surface plasmon. We study how such interaction changes by tuning the wavelength of the quantum dots along the polariton bands.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"58 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":"128825436","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 review recent progress in these areas and highlight our efforts in structuring all degrees of freedom of light; including the phase, amplitude, polarization state, and orbital angular momentum of light both in three-dimensional space and time. Notably, we showcase scenarios in which the propagation dynamics of structured vector beams are governed by a topological phase factor (i.e., the Berry phase) in addition to the regular propagation phase. This in turn redefines basic phenomena in optics encountered by these beams; such as Snell’s law, phase matching and resonance conditions.

The nanoantennas of meta-lens can be used to control the phase, amplitude, and polarization at well. The phase part is the most important part of the function of the meta-lens. However, so far, the phase distribution of meta-lenses has not been directly measured, which further hinders the quantitative evaluation of their performance. We have developed an interferometric imaging phase measurement system for meta-lens and meta-devices. This system can measure the phase distribution by shooting the interference pattern. The phase distribution of meta-lenses can be measured to quantitatively characterize the imaging performance. Our meta-lens phase measurement system can help for designers to optimize the design, for manufacturers to identify defects, thereby improving the manufacturing process. This work will pave the way for meta-lens in industrial applications.","PeriodicalId":118068,"journal":{"name":"Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX","volume":"1 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":"130823600","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}
