This perovskite-based plasmonic upconverting nanolaser features a record-small mode volume and an ultralow lasing threshold. Besides, we observed temporal coherence of the emission, which is an important feature of lasing. To co-optimize the pump photon absorption and the upconverted photon emission rate, the lasing result was made possible based on plasmonic titanium nitride. Moreover, we also demonstrated a new concept of lasing from a quantum emitter utilizing an intense localized electromagnetic field. A continuous-wave lasing was observed from single perovskite (CsPbBr3) quantum dot in a gap-plasmon nanocavity with an ultralow threshold of 1.9 Wcm-2 at 120 K. In the end, we will discuss the outlook for perovskite plasmonic nanolasers as on-chip light sources for bio-imaging, optical communication applications.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"04 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":"127255077","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 particular, we discuss how BIC-empowered dielectric metastructures can be used to generate efficiently high-order optical harmonics from bulk and to boost the intrinsic nonlinearity of transition metal dichalcogenide (TMD) flakes. We explore TMD resonators composed of structured dielectric arrays and individual nanoparticles for strong light-matter coupling phenomena. We discuss the extension of metasurface functionalities for biosensing applications in biomarker detection and quantum information processing with entangled photons. Finally, we demonstrate how tunability of BICs in the momentum space can be used to realize a novel type of efficient lasing based on a finite-size cavity with a small footprint.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"135 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":"127691680","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 electromagnetic wave can be manipulated with its phase, polarization, and amplitude at will. Nowadays, the demand for photonics is extended from classical to quantum optics. With the advent of the post-Moore era, the fabrication technology of the semiconductor industry has faced the problem of the physical limitation approach. They have urgently needed to find out new methods and new physics to break through this dilemma. Quantum optics technology is the most suitable solution for this situation. Here, the design, fabrication, and application of the novel optical meta-devices are reported from classical to quantum optics in this talk. The meta-lens array with achromatism is used to demonstrate a light field system for imaging and sensing. The integrated meta-lens array is used to demonstrate a high dimensional quantum light source chip with excellent performance of quantum fidelity.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","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":"131762551","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}

To do this, we experimentally characterize and extract the permittivity. We have used the epsilon-near-zero (ENZ) feature of hyperbolic metamaterial as a substrate to manipulate the resonance of plasmonic nanoantennas. We demonstrate that the vanishing index of the substrate slows down the resonance shift of the antenna, known as pinning effect. Moreover, we have controlled the pinning effect. Later, we show by optically pumping with fs pulses at a proper wavelength the ENZ point of the structure alters, in comparison to the linear case. The change in the effective permittivity happens in the order of unity, leading to ultrafast light-induced refractive index change. The localized surface plasmon resonance of metal nanoantenna is significantly influenced by the size, shape, and environment but also its substrate.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"8 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":"128186361","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}

To incorporate these devices into current telecommunication platforms, integration with photonic waveguide architectures is a must as they present the most mature, widely used commercial photonic device platform today. Here, we present a new class of waveguide-integrated reconfigurable all-dielectric metasurfaces utilizing high refractive index phase change chalcogenides and discuss the unique considerations, design, and physical principles that are essential for integrating such nanostructures into waveguides where illumination is provided through controlled evanescent coupling of guided modes into the metamaterial structure.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"146 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":"123780818","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}
