They play an important role in various applications like imaging systems, laser-beam shaping, bio/medical-optics, etc. We propose methods for the modeling of diffractive and meta-lenses based on the concept of the fast-physical-optics approach. A diffractive or meta-lens can be modeled as a series of structures functioning locally (e.g. local gratings) on a base interface. Each local structure introduces a certain local phase modulation, and by putting all of them together, the lens functionality can be achieved. In our approach, the rigorous Fourier modal method (FMM), also known as the rigorous coupled wave analysis (RCWA), is applied for the analysis of the local micro-/nanostructures, with all vectorial effects and possible higher-order effects taken into consideration; then the phase modulations can be collected for the lens function modeling. In this manner, a multi-scale simulation of optical systems with diffractive/meta-lenses becomes feasible and efficient in practice.","PeriodicalId":438926,"journal":{"name":"Optical Modeling and System Alignment","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117157775","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}

Wyrowski","doi":"10.1117/12.2529603","DOIUrl":"https://doi.org/10.1117/12.2529603","url":null,"abstract":"Optical fibers are widely used for collecting and monitoring light signals in modern optical metrology systems. The use of fibers helps reduce the size of optical system and makes the interconnection between systems convenient. But on the other side, the design and analysis of systems containing fibers often go beyond traditional ray-optics modeling. Because the interaction between light and fibers, with core diameter only several micrometers, requires electromagnetic field solvers. In this work, we present a physical-optics-based modeling technique for the complete optical system, including large-scale lenses and micro-scaled optical fibers. We investigate the coupling of electromagnetic fields into fibers using different lens systems, and especially, we perform tolerance analysis of given system with respect to shift and tilt of the fiber, as well as other components in the system.","PeriodicalId":438926,"journal":{"name":"Optical Modeling and System Alignment","volume":"299 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131611253","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}
