Summary: One-dimensional photonic crystals (1DPhCs) combined with a thin Au layer are used to demonstrate Tamm resonances for potential sensor applications. Two different structures with TiO2/SiO2 bi-layers and a termination layer show Tamm resonances within different band gaps. The first structure exhibits wide band gaps over the visible and near-infrared spectral range, and the Tamm resonance depth and width depend on the thickness of the Au layer. The second structure, with band gaps in both spectral ranges, shows deep Tamm resonances for a 20 nm Au layer thickness.

Summary: This paper proposes a multichannel terahertz optical filter based on a one-dimensional photonic crystal with a third-order Fibonacci structure, including a bulk Dirac semimetal. The tuning of the optical properties of the proposed structure has been theoretically studied as a function of the Dirac semimetals' Fermi energy. Furthermore, the effects of the Fibonacci structure's periodic number and light's incident angle on optical channels were investigated. The results reveal that changes in the Fermi energy and incident angle remarkably affect the frequency and transmission of the optical channels. Additionally, the number of optical channels increases by increasing the periodic number of the Fibonacci structure.

Previous studies focused on achieving deep nanopores with high aspect ratios, but resulted in structural imperfections. This study aims to realize cylindrical nanopores for better comparison with theory and simulations. By optimizing etching parameters and implementing a multistep process, cylindrical nanopores with high aspect ratios were achieved, suitable for silicon nanophotonic structures.

Summary: This study proposes a rigorous method to classify the dimensionality of wave confinement by utilizing unsupervised machine learning, aiming to enhance the accuracy of the recently presented scaling method. The standard k-means++ algorithm and a model-based algorithm are applied to 3D superlattices of resonant cavities embedded in a 3D inverse woodpile photonic band gap crystal. The results are compared with each other and with the direct usage of the scaling method without clustering. Cluster validity indices are investigated to find the set of confinement dimensionalities present in the system. The study concludes that the most accurate outcome is obtained by first applying direct scaling and subsequently utilizing a model-based clustering algorithm.

Summary: This paper investigates the possibility of manipulating nanoparticle scattering using wave-front shaping, and finds that even a single nanoparticle can support multiple strongly scattering eigenchannels. Selective excitation of eigenchannels is achieved by sending in shaped wave fronts, and distinct field distributions are observed. The paper also explores the backscattered spectra and reveals the existence of spectral correlations for an eigenchannel. The findings offer a flexible tool to manipulate light scattering of a single nanoparticle and provide insights into new features of nanoparticle scattering.

Summary: Ptychography is a lensless computational imaging method that uses diffraction patterns to determine the amplitude and phase of an object. This study presents a setup to simultaneously capture signals near the optical axis and scattered at high diffraction angles, and proposes an algorithm for reconstructing the object based on the recorded signals. The resolution of the reconstructed image is significantly improved by jointly reconstructing the object from low and high diffraction angle images.

Summary: We investigated the unphysical regions of three popular approximations to the radiative transfer equation (RTE) and found that the delta function correction to P-3 can eliminate the unphysical range in the forward scattering. By comparing the predictions of these approximations to exact Monte Carlo simulations, we obtained relative error maps for the albedo and anisotropy of the scatterers. Our results show that the P-1 approximation is significantly inaccurate unless the sample scatters purely isotropic and elastic, while the P-3 approximation outperforms P-1 in terms of accuracy in its physical range.
