By focusing on a hybrid cladding approach to alleviate these issues, we demonstrate substantially improved device performance of ICLs compared to earlier reported ICLs of a similar design in the 3–4 µm wavelength region. These improvements

Localized surface plasmon resonance properties dependence of green-synthesized Fe3O4/Ag composite nanoparticles on Ag concentration and an electric field for biosensor application Photonics Nanostruct. Fundam. Appl. (IF 2.7) Pub Date : 2023-10-13 Sari Wahyuni, Muhammad Riswan, Nanang Adrianto, Mahardika Yoga Dharmawan, Rivaldo Marsel Tumbelaka, Rona Cuana, Nurul Imani Istiqomah, Adhistinka Jiananda, Shania Garcia, Edi Suharyadi
The use of green-synthesized Fe3O4/Ag composites nanoparticles (NPs) on the surface plasmon resonance (SPR) system induced by the electric field generates the effect of electrooptic-localized surface plasmon resonance (EO-LSPR). EO-LSPR is the promising method to increase dispersibility, generate plasmons, bind to biomolecular targets, modify the refractive index, and increase the SPR signal. Green

Coupled nano-squares with optical response in nonlinear modes; Suitable substrate to control light by light for quantum applications Photonics Nanostruct. Fundam. Appl. (IF 2.7) Pub Date : 2023-10-11 Sepehr Razi, Mahdi Khalili Hezarjaribi, Mahmoud Mollabashi
Nonlinear response of a nano-structure including two square quantum dots (QDs) of identical material but dissimilar sizes is discussed by considering possible quantum interferences. Density matrix approach is developed to extract physical characteristics of the system by considering Hamiltonians including couplings of the excitons to thermal bath and the possible intra-dot relaxations as well as the

Dual-core-enhanced surface plasmon resonance for sensing high refractive index liquid based on photonic crystal fiber Photonics Nanostruct. Fundam. Appl. (IF 2.7) Pub Date : 2023-09-29 Yundan Xia, Kaiyan Bi, Yushuo Duan, Meijie Shi, Exian Liu
A dual-core photonic crystal fiber sensor based on surface plasmon resonance is theoretically proposed for the high-sensitive detection of high refractive index liquid analytes. Dual-core construction can effectively enhance the coupling effect between the fiber-core mode and the surface plasmon polariton modes, leading to sharp loss peaks at the resonance wavelengths. As the refractive index of the

2D compound structures with deep subwavelength period on silicon fabricated by double time delayed femtosecond laser beams Photonics Nanostruct. Fundam. Appl. (IF 2.7) Pub Date : 2023-09-29 Kang Jin, Nan Zhang, Wei Wang, Yongjian Hao, Bing Liu
In this work, two orthogonally polarized femtosecond laser beams are employed to irradiate a p-doped silicon wafer with an electrical resistivity of 0.008 Ω·cm. It is interesting to find that 2D compound structures composed of sub-wavelength periodic ripples and deep sub-wavelength nanodot array can be produced when proper laser fluence and time delay between the dual laser beams are used. The formation

Radial and axial photonic galleries of dielectric rings Photonics Nanostruct. Fundam. Appl. (IF 2.7) Pub Date : 2023-09-27 A.P. Chetverikova, M.F. Limonov, M.S. Sidorenko, K.B. Samusev, N.S. Solodovchenko
A new picture of the photonic eigenmodes of dielectric rings with a rectangular cross section is presented, which is fundamentally different from those of whispering gallery modes of the disc. The low-frequency photonic spectrum is formed by two types of galleries: one type begins with radial Fabry-Pérot-like resonances, and the other with axial Fabry-Pérot-like resonances, in both cases the galleries
