Through the symbolic calculation and the Cole-Hopf transformation, we obtain the solution of the original equation. Especially, we introduced vectors as tools to get the rational solutions of the equation. We make plots according to select different values of parameters, and the plots of various forms of solutions are dynamically analyzed to understand their physical significance. For the selection of trial functions, the first type is the positive quadratic functions, which can be used to obtain lump solutions and rogue wave solutions. The second type is the superposition of positive quadratic functions and positive arbitrary functions, resulting in an interaction solution consisting of both rational solution and arbitrary function solutions. We will provide examples to illustrate the interaction solutions formed by the superposition of positive quadratic and exponential functions, the superposition of positive quadratic, exponential and trigonometric functions, and the superposition of positive quadratic, exponential, trigonometric and hyperbolic functions.

Cross-phase modulation (XPM) crosstalk is a significant problem in these systems that gets worse with higher frequencies, longer fibre lengths, and smaller channel spacing. Using coupled equations and the nonlinear Schrödinger equation (NLSE), this study compares and analyses the performance of XPM crosstalk in the W band (75–110 GHz) and V band (40–75 GHz), considering the effects of higher-order dispersion up to the eighth order. Examining XPM-induced crosstalk over fibre lengths up to 50 km, input energies up to 20 mW, and different channel spacings are all included in the scope. The findings show that the relationship between XPM crosstalk and frequency, fibre length, and input power is exponential. In terms of reducing XPM crosstalk, the Schrödinger equation-based model performs better than the coupled equation. The optimisation of RoF systems for next-generation, high-capacity optical communication networks can be facilitated by the insights gained from this study.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726733","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}

Range measurement can be achieved by modulating the phase or frequency of continuous lightwave, called Frequency-Modulated CW (FMCW) and Phase-Modulated CW (PhMCW) Lidar, respectively. In this study, we model the FMCW and PhMCW Lidar links using Max-Optics Studio and evaluate the performance of the two Lidar systems under different modulator transmission points and detection schemes. Numerical atmospheric channels are used to simulate free-space light transmission. The results show that the direct and coherent detection schemes present excellent SNR at the quadrature and peak. The PhMCW has a 3-dB signal-to-noise ratio (SNR) advantage in long-range direct detection, while the FMCW demonstrates superior performance in coherent detection, with an average SNR improvement of 9-dB. FMCW achieves a high SNR through spectral analysis processing but at the cost of increased linearity modulation complexity and expensive light source. At the expense of integration and the need for higher sampling rates on the received side, PhMCW offers a practical alternative for scenarios where cost-effectiveness and real-time performance are prioritized. With the reduction of device cost and system complexity, CW Lidar will stimulate new vitality in the optical sensing.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726734","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}

The proposed structure unit cell consists of a 2 × 2 CNWs structures with different top diameters. The electrical performance is investigated via the finite element method where all recombination losses are taken into consideration. The optical results reveal that the suggested structure with optimized CNWs diameters can support broad Mie resonances with improved optical generation rate. Further, the generated carriers are confined inside the large CNWs size with reduced surface recombination. Therefore, the modified CNWs design significantly reduces the recombination losses and enhances the electrical performance. Using ideal surface passivation, the conversion efficiency (CE) of the modified CNWs reaches 19.5% with an enhancement of 11.4%, 14%, and 18.9% compared to the conventional conical NWs with diameters of 100 nm, 240 nm, and 400 nm, respectively. This is due to the asymmetry of the reported CNWs which widens the optical absorption and increases the CE. Further, the different diameters improve the index matching between the CNWs with enhanced light confinement and absorption within the large CNWs’ diameters. Therefore, the generated carriers are extracted with low sidewalls recombination rate associated with the large CNWs structure. The CE is strongly diminished to 1.2% that is lower than 1.7% of the conventional design with 400 nm diameter without surface passivation. Hence, effective sidewall passivation for the proposed CNWs design is essential to transform the efficient optical performance into a high electrical output.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716894","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}
