By utilizing a complex envelope traveling wave transformation, we establish the corresponding dynamic system and analyze its chaotic behaviors. Furthermore, we apply the trial equation method to obtain a comprehensive set of exact chirped solutions, including solitary wave solutions, Jacobi elliptic function double periodic solutions, rational solutions, and singular periodic solutions. Notably, the method allows us to determine the form of solutions based on the physical parameters. These results can be used to fully describe the structure of chirped solutions. Finally, we present graphical representations of these diverse solutions and their chirps, clearly demonstrating the rich dynamical behaviors of the system and how they evolve under different parameter values, consistent with analytical constraints identified. Importantly, the chirped solutions we obtain have direct implications for practical photonic applications such as optical pulse compression, dispersion management in fiber optics, and signal processing in ultrafast laser systems. Moreover, the analysis of chaotic dynamics and the derivation of analytical solutions contribute to addressing key challenges in nonlinear optical systems, including the control of instabilities and the design of robust pulse propagation models. These findings provide both theoretical insights and practical tools for advancing photonic technologies governed by nonlinear wave equations.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 9","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057602","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 differential trapping is governed by key system parameters such as laser power, particle number density, pulse repetition rate, pulse width, numerical aperture of the objective, and beam polarization.

Additionally, the hill-like potential causes blueshifts in resonance peaks of PCS for <span>(1srightarrow 2p)</span> transitions and redshifts for <span>(2p rightarrow 3d)</span>, whereas the inverse potential consistently causes redshifts for all transitions.

The present research utilizes computer simulations to examine the impact of transition metal (Pd and Pt) atom adsorption on antimonene, concentrating on its stability, optical, and electronic properties using first-principles density functional theory (DFT) calculations. The adsorption of Pd and Pt reduces the band gap, whereas the semiconducting nature of antimonene remains unchanged. The maximum absorption coefficient of pure antimonene primarily occurs in the visible spectrum, whereas it decreases significantly in the near-infrared region. The adsorption of Pd and Pt on antimonene enhances the absorption coefficients in the near-infrared region compared to pure antimonene. The adsorption of Pt significantly enhances the peak absorption coefficient of antimonene, including both the infrared and visible spectra, with a redshift. The dielectric constant and refractive index of antimonene exhibit substantial alterations, leading to noticeable peaks detected at reduced energy levels post-adsorption. The analysis reports that the structure of Pt-adsorbed antimonene exhibits the highest stability and light absorption compared to all other structures examined. This makes it appropriate for stable light absorption within the desired range of the visible and near-infrared spectrum. This enhanced optical absorption enables the utilization of antimonene in infrared sensors, photovoltaics, photodetectors, and solar cells.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 9","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934762","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}
