In this talk I show that both all-optical and electro-optical nonlinearity can be strongly enhanced at the slow-light effect epsilon-near-zero (ENZ). I share our recent experimental demonstrations including (a) temporally tailoring ENZ nonlinearity (Optics Letters 2020), (b) spectrally 400nm broadband ENZ enhancement, (b) GHz-fast yet micrometer-compact electro-optic modulator within a MZI-Silicon-ITO hybrid platform (OPTICA 2020, Scientific Reports 2021), and (c) Kramers-Kronig-enhanced electro-absorption modulator (NANOPHOTONICS 2019). Together, these technologies show that monolithic integration of TCO into PICs provides functionality beyond Silicon photonics with application in datacom, sensing, and neuromorphic computing.","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":"114510001","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 demonstrate optically and electrically pumped near-infrared exciton-polaritons at room temperature and the possibility to tune between weak, strong and ultrastrong coupling in field-effect transistors [Nat. Mater. 2017, 16, 911] and electrochromic devices [ACS Photonics 2018, 5, 2074]. While these polaritons are observed in simple metal-clad microcavities, coherent coupling of carbon nanotube excitons with hybrid plasmon-photonic modes results in plasmon-exciton polaritons (‘plexcitons’) [Nano Lett. 2018, 18, 4927]. Furthermore, covalent functionalization of SWCNTs creates luminescent defects with red-shifted emission. Without changing the polariton branch structure, radiative pumping through these emissive defects leads to an up to 10-fold increase of the polariton population in microcavities with detunings for large photon fractions [ACS Photonics 2021, 8, 182].","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","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":"122380460","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}

It is widely known that strong material absorptions resonant with an optical cavity can lead to the formation of new hybrid light-matter states called polaritons. Strikingly, cavity-modified material properties (e.g., electrical conductivity, optical emission/absorption, chemical reaction rates and branching ratios) have been demonstrated and, the degree to which they are modified, shown to depend on the energy positions of these new hybrid states. Our work shows real-time tuning of these states through electrochemical cycling and optical excitation of the coupled species.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"45 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":"132476752","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}

These structures are akin to metal-insulator-metal (MIM) architectures widely used in nanophotonics and are key to the realization of a range of reconfigurable and addressable metasurfaces. Therefore, the application of nanophotonic design principles to such electronic platforms provides an unexplored path towards the integration of nanophotonic technologies into telecommunication and computing platforms. We show here that these crossbar-architectures can be engineered to act as addressable metasurfaces exhibiting, multispectral optical resonances forming the basis for next-generation optical computing systems, while still preserving their electronic functionality.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"118 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":"117171739","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 demonstrate time diffraction from a time slit in an unstructured metasurface. In a pump-probe experiment, excitation of the Berreman mode of a thin film of Indium-Tin-Oxide over gold leads to strong, efficient all-optical modulation of the film, and to time diffraction of the probe. In comparison to previous works in unstructured epsilon-near-zero films, we obtain a 6 nm frequency shift and a 23 nm broadening using lower intensities and a significantly lower thickness of 40 nm, which demonstrates the minimal footprint of the structure. The deeply subwavelength nature of the sample makes a time-varying interpretation simple and efficient, paving the way for time-dependent architectures for ultrafast optical experiments.","PeriodicalId":389503,"journal":{"name":"Metamaterials, Metadevices, and Metasystems 2021","volume":"87 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":"122750030","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}

By tailoring the geometry of the building blocks of metamaterials and engineering their spatial distribution, we can control the amplitude, polarization state, phase and trajectory of light in an almost arbitrary manner. However, the conventional physics- or rule-based approaches are insufficient for designing multi-functional and multi-dimensional metamaterials, since the degrees of freedom in the design space become extremely large. Deep learning, a subset of machine learning that learns multilevel abstraction of data using hierarchically structured layers, could potentially accelerate the development of complex metamaterials and other photonic structures with high efficiency, accuracy and fidelity.
