Additionally, numerical simulations are conducted to analyze the average intensity of the PCMAVB across different biological tissues at various propagation distances and under changing beam parameters. The spreading characteristics of the analyzed beam in turbulent biological tissues are affected by the refractive index of biological turbulence and the initial beam parameters, including coherence length, modification parameter, beam order, topological charge, and beam waist width. The results show that increasing the source parameter enhances the PCMAVB's resistance to turbulent biological tissues.

Nonetheless, achieving higher or improved sensitivity in these sensors for detecting specific biomolecules, such as female reproductive hormones, remains an ongoing challenge. Estrogen is a crucial hormone in the female reproductive system, playing a vital role in regulating menstrual cycles, supporting pregnancy, and maintaining bone density and cardiovascular health. Therefore, this work aims to overcome the limitations by introducing a plasmonic sensor to optimize detection accuracy. The optical sensor structure, known for its immunity to electromagnetic interference and adaptability in various sensing applications, provides an ideal platform for precise RI detection. The sensor design has a unique plus-shaped cavity with layers of gold (Au), iron oxide(II) (FeO), and graphene oxide (GO). Incorporating Au and FeO on the sensor surface improves light-matter interactions and generates surface plasmon. The FeO has been synthesized using the combustion technique and its surface morphology is studied using scanning electron microscopy. The GO layer is introduced to improve the biocompatibility of the sensor. The model is tested within the RI range of 1.3332–1.3359 for the concentration level in the blood sample of 0–1.3 nmol/L of estrogen. Through two-dimensional finite difference time domain simulations, the sensor demonstrates an impressive detection autocorrelation coefficient of 99.27%. This level of precision offers significant potential for applications in medical diagnostics, particularly in monitoring biomolecule levels for reproductive health and endocrinological studies.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 5","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925534","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}

Furthermore, the engineering of these states through ABD, a longer interaction time regime, guarantees the high enough success probability approaching unity and good fidelities with minimum decoherence risk.

To compensate for pulse broadening effects both Fiber Bragg Gratings (FBGs) and Dispersion Compensating Fibers are widely used, evaluated, and documented. This work investigates a new method to mitigate the dispersion effect using a combination of DCF and a multi-stage FBGs. The proposed system includes multiple designs that use more than one stage of cascaded FBG with a DCF to increase the effectiveness of the FBG network. In the proposed system, the Quality factor (Q-factor) and Bit Error Rate (BER) results for each design are evaluated using a variety of FBG apodization functions. Different profiles show different Q-factors over a range of Continuous Wave laser power ranging from −20 to 20 dBm, for FBG grating lengths up to 70 mm. The proposed model demonstrates a significant cost improvement of 97.5% for DCF length and 98.9% highest Pulse Width Reduction Percentage, using the OptiSystem software. Regression modeling and Machine Learning methods are also utilized in FBG and DCF systems. Through these approaches, we are able to predict the actions and characteristics of the system, which aids in determining the estimate of the number of phases necessary to achieve the optimal aspect ratio for the Q-factor with minimal BER, in addition to reduce cost and time consumed. This leads to better system performance as compared to previously published attempts.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 5","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11082-025-08169-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, in both transverse electric (TE) and transverse magnetic (TM) polarizations, the hybrid G/hBN/BP structure displays robust and anisotropic plasmonic response characteristics across the 5–15 µm wavelength range. Our findings reveal that the proposed structure achieves absorption rates of up to 70% of electromagnetic radiation at three distinct peaks for both polarizations.

Importantly, this triple-band absorber can be effectively tuned by adjusting the geometrical parameters and the doping levels in the graphene and BP layers.
