Dielectric nanostructures can reduce the surface light reflection of photovoltaic devices, similar to traditional antireflection films. Therefore, dielectric nanostructures are usually equivalent to the equivalent refractive index theory at the macro level. However, the macroscopic refractive index equivalent cannot reflect the manipulation ability of nanoscale light fields, and the influence of the nanoscale light field distribution on the photo-carrier generation and transport is usually ignored. Here, we introduce the self-assembly process of dielectric nanostructures on photovoltaic devices, which may lead to the controllable assembly of the density and number of layers on polycrystalline silicon solar cells. Based on this strategy, we investigate the enhancement effect of SiO2 nanosphere coating on textured silicon solar cells by systematically changing assembly conditions. Research has found that tightly packed SiO2 nanosphere monolayers generate a maximum relative efficiency improvement of 9.35%. This efficiency increase is attributed to the simultaneous enhancement of short-circuit current density and fill factor, which is different from the antireflection effect reported previously. Further, through semiconductor simulations, we theoretically analyzed the impact of nanoscale light focusing on the performance of photovoltaic devices. We explored the reasons for the changes in photocurrent, fill factor, and efficiency, providing ideas for more efficient nanoscale light focusing design and improving the performance of photovoltaic devices in the future.","PeriodicalId":149506,"journal":{"name":"SPIE/COS Photonics Asia","volume":"24 1","pages":"127630I - 127630I-6"},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139221716","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 paper briefly discusses one of the possible options for implementing a rotation angle sensor with a scale from a metasurface. As a scale it is proposed to use a metasurface – a dielectric onedimensional subwavelength array designed to operate in the infrared spectral range (at a wavelength of 1.5 microns). By the finite element method, a prototype of an optical angular scale from a metasurface has been developed by computer modeling. The results of an experimental study of a prototype of an optical angular scale from a metasurface are presented. The metasurface was made of tantalum oxide and deposited on a quartz glass substrate. For the convenience of the study, the size of the scales was set to 400 × 400 microns, but if necessary, it can be reduced by more than an order of magnitude. The dependences of the transmission spectra of the prototype scale on its rotation angle are experimentally investigated.","PeriodicalId":149506,"journal":{"name":"SPIE/COS Photonics Asia","volume":"56 1","pages":"1277307 - 1277307-10"},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139218118","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}

While computer-aided software tools such as CAD can improve the efficiency of photonic circuit development, they still face challenges in handling large-scale photonic integrated circuit (PIC) designs. In this paper, we develop a photonics design automation tool, called GT Photonics, which provides a flexible development environment capable of handling large-scale PIC designs. The GT Photonics platform integrates multiple high-performance photonic devices, including passive and active components, and allows users to freely develop and adjust the parameters of individual photonic devices. To enhance development efficiency, the platform offers various design methods, modular development, parameter unit reuse, customizability, and intelligent routing capabilities. These features streamline the development of complex photonic integrated circuits. To facilitate development, the platform defines a netlist view to record photonic device information and employs visual design methods for circuit visualization. Once the design is completed, the photonic circuit can be exported as a Graphic Data System version 2 (GDSII) file for performance simulation and validation. This article presents a case study involving the design of an optical phased array (OPA) using the GT Photonics platform. The case study encompasses the design process, design outcomes, and various design details. Photonic design automation holds significant importance for engineering and research endeavors.","PeriodicalId":149506,"journal":{"name":"SPIE/COS Photonics Asia","volume":"49 1","pages":"1276411 - 1276411-6"},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139225992","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}

But natural chiral materials typically exhibit a weak chiral response, making it challenging to detect them with great sensitivity. Chiral metasurfaces can greatly increase circular dichroism (CD), efficiently improve the interaction between light and chiral molecules, and enhance chiral sensing. Additionally, combining bound states in the continuum (BIC) to excite numerous high-Q-factor Fano resonances is a useful strategy for enhancing sensing performance in all-dielectric metasurfaces. With its extremely small linewidth and exceptionally high Q value, the Fano resonance created by the quasi-BIC mode can significantly boost the performance of the refractive index sensor. In this study, we combine BIC with chirality, break the structure's mirror and inversion symmetry to construct a chiral all-dielectric metasurface structure based on BIC. Fano resonances with simultaneously high Q value and strong CD are achieved for the chiral optical response. Meanwhile, we investigate its sensing properties to obtain high sensitivity and figure of merit (FOM) for refractive index sensing performance. Our research offers suggestions for applications such as the identification and separation of chiral biological substances.","PeriodicalId":149506,"journal":{"name":"SPIE/COS Photonics Asia","volume":"60 1","pages":"127730B - 127730B-6"},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139227954","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}

However, the challenge of achieving high endurance and efficiency for light conversion throughout the entire visible range using a single MOF crystal persists. In this work, we present the design of a non-centrosymmetric MOF based on a 1,3,5-benzenetricarboxylic acid ligand and Erbium (Er) ions, which demonstrates efficient and simultaneous generation of multiple second and third optical harmonics (SHG, THG) across a wavelength range of 400 to 750 nm. Through a combination of optical experiments we have confirmed the effectiveness of SHG and THG in the MOF single crystals. These phenomena are caused by the specific MOF space group and the associated dipole moment. The observation of coherent light conversion throughout the entire visible range by MOF single crystals under ambient conditions enables the realization of multicolor (up to 3) emission, which is essential for modern laser technologies.","PeriodicalId":149506,"journal":{"name":"SPIE/COS Photonics Asia","volume":"32 1","pages":"127730R - 127730R-6"},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139227958","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}
