An analysis was performed to evaluate critical optical and plasmonic parameters within the frequency range of 0.12–0.129 THz. A detailed parametric analysis was conducted, examining key sensing metrics including refractive index variations (n = 1.33–1.3461), sensitivity (S), figure of merit (FOM), detection limit (DL), and signal-to-noise ratio (SNR). Results demonstrate a significant enhancement in sensing performance, with optimal FOM values of 131.579RIU<sup>−1</sup> achieved at frequencies of 0.123 and 0.12 THz, and corresponding detection limit values reaching 0.013. The system exhibits stable spectral characteristics, maintaining a consistent full width at half maximum (FWHM) of 0.038 across the investigated frequency range. Peak sensitivity values of 5000 GHz/RIU were observed, concurrent with a constant detection angle (DA) of 26.316. The quality factor (Q) exhibited a decrease from 3.395 to 3.158 with decreasing frequency, indicating an optimal operational range. A controlled decrease in the dynamic range (DR) from 0.662 to 0.616 was also observed. The optimized parameters demonstrate the potential for implementing highly sensitive, reliable SPR platforms suitable for both clinical diagnostics and research applications in biomedical applications.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 5","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900861","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 waveguide uses Aluminum Gallium Arsenide, known as “silicon of non-linear optics”, as the core material. To achieve a flat and low dispersion profile, we employed dispersion engineering by optimizing the geometrical parameters of the waveguide. The optimized design features an all normal, flat top dispersion profile with values below—4.43 ps/nm/km across the spectral range of 4.8–7 µm achieving a dispersion value of − 1.71 ps/nm/km at the pump wavelength of 5 µm. Our simulation study, employing the split step Fourier transform method results in coherent supercontinuum spectrum broadening from 2 to 12 µm (40 dB level) and 2.1 to 9.8 µm (20 dB level) in 3 mm long waveguide when pumped with 5 µm secant hyperbolic pulses having pulse width 50 fs and peak power 6 kW. To the best of our knowledge, such broadband supercontinuum spectrum in mid-infrared region at the 20 dB level using waveguide geometry has been reported for the first time. Additionally, when pumped in anomalous dispersion region at 6 µm, our simulations result in supercontinuum broadening from 2.6 to 16 µm (40 dB level) in mid-infrared region under identical laser operating conditions. The proposed waveguide can serve as a promising candidate for on-chip supercontinuum sources and for diverse applications like frequency comb generation, early cancer diagnostic, chemical sensing and food-quality control.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 5","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892678","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 research not only identifies the optimal co-doping ratios of F and Ga but also elucidates the critical role of Ga in providing a substantial concentration of electron carriers. Concurrently, F is shown to effectively passivate oxygen vacancies, thereby enhancing the electron mobility of pure ZnO thin films. The results indicate that an 800 nm thickness ZnO film with an optimal doping composition of 3% atomic Ga and 1% atomic F (designated as FGZO), deposited on a glass substrate at 500 °C in an Argon atmosphere, achieves remarkable metrics: a carrier concentration of 6.33 × 10²⁰ cm⁻³, electron mobility of 40.59 cm²/V.s, and a resistivity of 2.7 × 10⁻⁴ Ωcm.

The sensor uses a triple-resonance response to detect spectral shifts caused by refractive index variations in diseased tissues and offers exceptional disease diagnostic performance. It’s simple yet innovative layered structure composed of Aluminum (Al) and Polyimide eliminates the need for complex fabrication processes and use of expensive or 2 dimensional materials which makes it a highly scalable and affordable solution in the field of advanced disease detection. With sensitivities up to 1.43 THz/RIU, a Figure of Merit of 17.54 RIU⁻¹ and a Quality Factor of 18.33, the biosensor is capable of detecting even the smallest changes in dielectric properties enabling early-stage diagnosis of infectious diseases like malaria and brain cancer. Completely polarization insensitive with wide angular stability of up to 70°, the sensor ensures reliable performance across a wide range of diverse diagnostic environments. This handy platform not only eliminates the reliance on disease-specific devices but also streamlines diagnostics which makes it ideal for resource-constrained healthcare settings. Its ease of fabrication, adaptability and ability to deliver precise, real-time and rapid results positions itself as a game-changer in personalized medicine, point-of-care diagnostics and global health initiatives while setting new standards for disease detection and management.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 5","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879719","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}

In addition to achieving higher relative diffraction efficiency of EIG by tuning system parameters, such as coupling field Rabi frequency, probe field detuning, and relative phase, the impact on diffraction efficiency becomes very small once the Rabi frequency continues to increase after the relative diffraction efficiency reaches its maximum value in the coupling field Rabi frequency regulation.
