An alternative, low SWaP solution is to implement a hybrid photovoltaic (PV)/electroabsorptive modulator (EAM) coupled with a retroreflector and use free space optical communication over 1.55 μm rather than RF communication. A design which minimizes parasitic losses and optimizes contrast ratio and cutoff frequency in a 1 cm2 device is discussed.","PeriodicalId":130368,"journal":{"name":"Nanoengineering: Fabrication, Properties, Optics, Thin Films, and Devices XVIII","volume":"113 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":"115547933","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 contrast to the current non-deterministic manufacturing process that cannot be deployed in large dimensionality, we innovatively import binary quasi-random sequences to generate QRNs deterministically without the restriction of the pattern size. Note that all 2D quasi-random patterns such as particle and channel types can also be converted into binary sequences by digitizing their 2D pattern images. Moreover, to bridge the gap between the nanostructure spatial arrangement and its optical performance, the star discrepancy calculation is employed as a guidance to evaluate and to optimize these binary QNRs given that the nanostructures’ uniformity is a key factor for light trapping. Finally, these binary QRNs are generated in a “pit-and-land” morphology so that they can be facilely and directly fabricated via optical disk recording technology.","PeriodicalId":130368,"journal":{"name":"Nanoengineering: Fabrication, Properties, Optics, Thin Films, and Devices XVIII","volume":"75 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":"122448194","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 demonstrate a hybrid top-down/bottom-up approach based on sol-gel dip-coating and nano-imprint lithography for the faithful reproduction of dHU metasurfaces in metal oxides (MOx). Nano- to micro-structures made of silica and titania can be directly printed over several cm2 on glass and on silicon substrates. Firstly, we describe the polymer mold fabrication starting from a hard master obtained via spontaneous solid-state dewetting. Then we address the effective dHU character of the master and of the replica and the role of the initial thickness of the sol-gel layer on the MOx replicas. Finally, these structures will be optimized towards their exploitation in many potential photonic applications like photonic devices (anti-reflection coatings, quantum emitters).","PeriodicalId":130368,"journal":{"name":"Nanoengineering: Fabrication, Properties, Optics, Thin Films, and Devices XVIII","volume":"237 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":"125756722","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 decided to design a filter with a new wavelength by combining two classical MDM structure Fabry-Perot cavities with different resonant wavelength. A cavity medium with high refractive index leads to angle-invariant performance up to 50˚. Moreover, only deposition is involved so that the device can be easily scaled over a large area. The described approach may provide new avenues for various applications, such as reflective displays and surface coatings for decoration and solar cells.","PeriodicalId":130368,"journal":{"name":"Nanoengineering: Fabrication, Properties, Optics, Thin Films, and Devices XVIII","volume":"41 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":"123333810","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}

Since there is a trade-off between color purity and brightness in a conventional single FP cavity, a peak separation in multiple FP cavities is exploited to achieve a more square-shaped spectral curve. Besides, controlling a resonance order in each cavity leads to a great suppression of a higher-order resonance for a red color filter. The presented results may be applied to various applications including display panels, decorations, and image sensors.","PeriodicalId":130368,"journal":{"name":"Nanoengineering: Fabrication, Properties, Optics, Thin Films, and Devices XVIII","volume":"78 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":"133778576","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}
