TFLN channel waveguides of rib and strip type: properties of guided modes
This study provides a comprehensive modal analysis of thin-film lithium niobate (TFLN) channel waveguides with rib and strip geometries, considering various crystal cuts (X-cut and Z-cut) and on-chip orientations. The finite-element solver in JCMsuite was used to rigorously compute the guided modes, taking full account of the material anisotropy and complex permittivity tensors. The software enabled extensive parameter scans to reveal modal effective indices, symmetry classes, polarization properties, and hybridization effects critical for integrated photonic device design.

3D nanoprinted fiber-interfaced hollow-core waveguides for high-accuracy nanoparticle tracking analysis
This work presents a novel fiber-integrated square-core hollow-core waveguide (HCW) fabricated via 3D nanoprinting, enabling high-precision nanoparticle tracking analysis (NTA) with near-aberration-free imaging. Finite element modeling (FEM) simulations performed with JCMsuite software were used to analyze the intensity distribution, polarization, and modal attenuation of leaky core modes within the HCW. The simulations provided critical insights into the guiding mechanism (anti-resonance effect), confirmed the high-purity excitation of the fundamental mode from the fiber, and aided in the design of the waveguide for optimal performance in NTA experiments.

On-chip hollow-core waveguides with integrated anti-resonant channels, enabled by 3D nanoprinting
This work introduces a novel three-channel on-chip hollow-core waveguide design operating via the anti-resonant effect. To analyze the modal behavior, inter-channel coupling, and polarization-dependent losses, detailed finite element method (FEM) simulations were performed using JCMsuite. The numerical simulations were essential for understanding the underlying physical principles and guided the experimental validation of the nanoprinted structures.

Resonance modes in microstructured photonic waveguides: efficient and accurate computation based on AAA rational approximation
This work presents a framework for the efficient and accurate computation of fundamental resonance modes in photonic waveguides, based on the AAA rational approximation. The method computes modes selectively, prioritizing those most relevant by applying specially chosen light sources, thereby avoiding the need to calculate many unwanted modes (e.g., cladding or higher-order modes). The approach was demonstrated by computing the fundamental mode of a hollow-core photonic crystal fiber, with numerical solutions obtained using the finite element solver JCMsuite.

Estimation of losses caused by sidewall roughness in thin-film lithium niobate rib and strip waveguides
Optical propagation losses in thin-film lithium niobate waveguides are measured using the Fabry-Pérot method. A perturbational model attributing losses to sidewall roughness is developed to predict attenuation for different waveguide geometries. The finite-element solver in JCMsuite is used to rigorously compute the guided mode profiles of the idealized, lossless waveguides, which are essential for the loss estimation procedure.

Symmetry-protected TM modes in rib-like, plus-shaped optical waveguides with shallow etching
This work investigates dielectric optical waveguides designed to suppress lateral leakage of TM-polarized modes, a common issue in standard rib waveguides with shallow etching. The proposed "plus-shaped" waveguide achieves this by using a vertically symmetric core structure. JCMsuite's fully vectorial finite-element eigensolver was used to compute and validate the modal properties, confirming the absence of leakage and loss for these symmetry-protected TM modes.
