Our work introduces several novel aspects, including a systematic comparison of graphene and phosphorene as dark mode materials, revealing their distinct absorption characteristics and stability. We also introduce mixed-material structures, combining graphene and phosphorene dark modes to achieve tailored absorption profiles. Furthermore, we analyze dynamic tunability through Fermi level adjustment in graphene layers, demonstrating the potential for adaptive sensing applications. A detailed study on the impact of sample layer positioning on sensing performance provides crucial insights for optimizing refractive index sensors. We observe that structures incorporating diverse dark mode materials exhibit enhanced absorption peaks at higher frequencies. The asymmetric configuration allows for complex mode interactions, leading to the formation of multiple Fabry–Perot cavities and resultant absorption peaks. Our findings show that mixed-material structures can achieve sensitivities up to 14.13 THz/RIU with a figure of merit of 33.885 1/RIU, surpassing many existing designs.

The influence of the waveguide system parameters on the spatial profiles of the field distribution in the direction transverse to the interface is analyzed in detail. The height of the peak intensity of waves in the case of self-focusing nonlinearity increases, and that of waves in the case of defocusing nonlinearity decreases with an increase in the effective refractive index. The maximum intensity of the wave field in a self-focusing medium can be located in the nonlinear near-interface layer, and the peak can move to the hyperbolic gradient medium with an increase in the characteristic distance of the hyperbolic profile, however, the maximum intensity of the wave field in a defocusing medium can always be located in the hyperbolic gradient medium. The influence of the waveguide system parameters on the control of the width of the formed near-interface layer for the waves of the two types under consideration differs significantly. Comparative analysis of the relative intensities and relative power flows shows that their behavior is identical depending on the control parameters of the waveguide system at a qualitative level. The largest share of energy flow is concentrated in the nonlinear near-interface layer in the case of self-focusing nonlinearity and it is concentrated in the hyperbolic gradient medium in the case of defocusing nonlinearity.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 3","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This allows the complexity to be reduced by decreasing the polynomial order of the evaluation of the Faber algorithm, while at the same time decreasing the overall runtime. Compared to common Local Time Step methods, the time step size of each individual area with this approach is already synchronized with a predefined global time step size. In general, the investigated approach is especially interesting for applications that demand a high spatial resolution, such as in the field of nanophotonics and THz-technology.
