In which, the IFTA is executed for a coarse solution; then, FMM is for a precise solution. We take a 5 × 5 metasurface DOE with nanorods as an example to explore the improved FMM (IFTA + FMM). By varying the diameter of the nanorods on the metasurface DOE, a 5 × 5 spot array DOE has been created with a diffraction angle of 48°× 48° in the far field. The analysis results show that the improved FMM (IFTA + FMM) requires fewer iterations, about 17 times, while direct FMM requires about 70 times. The DOE designed with an improved FMM achieves a diffraction efficiency of 79.6% with a uniformity of 24.2%, while the DOE designed with a direct FMM shows a diffraction efficiency of 76.9% with a uniformity of 27.7%. The improved FMM (IFTA + FMM) shows a similar accuracy, but is more timesaving, simple, and intuitive.","PeriodicalId":509797,"journal":{"name":"Journal of Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140653935","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, on-chip integrated photonics platforms are promising platforms enabling us to take advantage of the promise of topologically robust modes against inevitable fabrication defects. Here, we propose to study the SSH model superimposed in an optical ring resonator in a quantitative way using electromagnetic simulations. We are interested in lhe localized states that appear when a topological phase transition is introduced into the ring. In particular, we examine the extent to which topologically protected modes maintain their properties in the presence of random deformations in the surrounding lattice. We find that the modes maintain their properties when small amounts of disorder are introduced into the system. We also study loss mechanisms in the localized states, distinguishing between losses to the adjacent waveguide and to radiation, finding that the topological protection only applies to the former.","PeriodicalId":509797,"journal":{"name":"Journal of Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140660895","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}

Nevertheless, conventional CMI implementations necessitate an additional step to acquire prior information about the modulator function, introducing complexity and reliance on other imaging techniques. Previous attempts to mitigate the requirement for precise modulator information using diverse objects have encountered slow convergence speeds. Here, we present an improved CMI algorithm, termed as blind CMI, which achieves blind recovery without prior knowledge of the modulator. This is achieved by leveraging sample priors and incorporating momentum acceleration. We validate our method through numerical simulations and optical experiments, demonstrating that the proposed blind CMI outperforms other state-of-the-art methods in terms of both convergence speed and reconstruction quality.","PeriodicalId":509797,"journal":{"name":"Journal of Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140685334","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}
