As the demand for scalable and complex on-chip nanophotonic devices with multi-wavelength and multi-mode optical functionalities increases, fast and efficient design algorithms have become an essential tool in silicon photonics. Although inverse design coupled with adjoint optimization has emerged as a powerful method to design such devices by requiring only two simulations in each iteration of the optimization process, these simulations still make up the vast majority of the necessary computations, and render the design of complex devices with large footprints computationally infeasible. Here, we present a substantial speed-up in the finite-difference frequency-domain (FDFD) simulations by introducing a factorization caching approach, and significantly reduce the computational requirements for device optimization. Specifically, we cache the symbolic and numerical factorizations of system matrices corresponding to discretized Maxwell's equations, and re-use them throughout the entire optimization. Using this method, we reduce the majority of the computational operations in the FDFD simulations and drastically improve the simulation speeds. To demonstrate the resulting computational advantage compared to conventional FDFD methods, we show simulation speedups reaching as high as 8.5-fold in the design of broadband wavelength and mode multiplexers. These results present significant enhancements in the computational efficiency of inverse photonic design, and can greatly accelerate the use of machine-optimized devices in future photonic systems.

While the circular polarization of electromagnetic waves is well known from its poplar definition, its handedness is not uniquely defined, even with given phase convention, observer location and phase difference. For example a circular polarization Ex+jEz (j=sqrt(-1)) traveling along y axis has opposite handedness of the polarization to Ex+jEy traveling in z axis, counter-intuitively. This cannot be explained by the conventional definition, due to the lack of clarity of the definition. In general, when there are two orthogonally linearly-polarized plane waves, say E1 and E2, choice of the reference wave to be E1 or E2 and application of the phase difference to the other wave are ambiguous. This causes confusions and sometimes contradictory results at least in simulations. This paper suggests the necessary and sufficient conditions with the help of the propagation vector and magnetic fields to define uniquely the handedness of a circular or elliptical polarization and thus a desired handedness can be correctly injected in a simulation. The newly proposed triad is added to the conventional definition for easy determining the handedness. The unique handedness of a circular polarization is critical in design, simulation, quantification of polarization-sensitive nanophotonics devices where wave can travel in 4 pi space along any arbitrary direction.

Accurate simulation is a critical requirement for modern optical systems, but precise theoretical modeling can be challenging due to various factors such as misalignment, theoretical approximations, and instrument errors. This paper presents the black-box simulation method, which addresses these limitations by training the optical system model using the optical field outputs. This approach leads to more accurate simulations, making it possible to effectively train optical Neural Network systems for improved performance.

The use of 3D Monte Carlo simulations for the study of an indirect time of flight (iToF) pixel revealed underlying information compared to conventional simulation tools. Experimental tendencies and results are systematically compared with results obtained numerically. During the sensor operation, iToF pixels reconstruct the depth information using an optical signal modulated in intensity at high operation frequencies of hundreds of MHz. A demodulation operation samples the photogenerated charges at different times in a single pixel. An efficient transfer is dependent of the charge carrier path in the pixel volume. Through the coupling of 3D Monte Carlo with a commercial Poisson solver and optical simulation tools, a complete and accurate simulation methodology was developed allowing the estimation of iToF main figures of merit such as demodulation contrast, parasitic light sensitivity and quantum efficiency. The method consists of generating a light impulse and studying the distribution and collection of each unitary charge in time through MC simulations. Detailed information can be obtained in the 3D volume of a pixel for the photogenerated carriers. The efficiency of charges transfer from the pixel volume to sensing nodes is given at the operation frequency by the demodulation contrast. The electrostatic potential barriers reducing the transfer efficiency can be easily identified and lost photogenerated carriers can be estimated. The prediction accuracy of Monte Carlo simulation is further improved through the coupling of photogeneration and electron mobility profiles extracted from optical simulation and drift-diffusion-based-technology computed-aided design tools respectively. A non optimized small pitch pixel was optimized thanks to these advanced multi-physics simulations.

Rigorous Coupled Wave Analysis (RCWA) method is highly efficient for the simulation of diffraction efficiency and field distribution patterns in periodic structures and textured optoelectronic devices. GPU has been increasingly used in complex scientific problems such as climate simulation and the latest Covid-19 spread model. In this paper, we break down the RCWA simulation problem to key computational steps (eigensystem solution, matrix inversion/multiplication) and investigate speed performance provided by optimized linear algebra GPU libraries in comparison to multithreaded Intel MKL CPU library running on IRIDIS 5 supercomputer (1 NVIDIA v100 GPU and 40 Intel Xeon Gold 6138 cores CPU). Our work shows that GPU outperforms CPU significantly for all required steps. Eigensystem solution becomes 60% faster, Matrix inversion improves with size achieving 8x faster for large matrixes. Most significantly, matrix multiplication becomes 40x faster for small and 5x faster for large matrix sizes.

Hexagonal III-nitride semiconductors exhibit internal polarization fields along their c-direction. In regions with graded mole fractions, the polarization gradient creates bound volume charge densities. Due to their electrostatic effect, they affect the balance of mobile charges, and can lead to polarization induced doping. In this contribution, drift-diffusion type simulations are employed in order to analyze a pn-junction based on polarization induced charges, and an analytical formula for calculating the bound charge density is given.

Germanium-on-silicon (Ge-on-Si) single photon avalanche diodes (SPADs) operating in the short-wave infrared (SWIR) have various applications such as long-range eye-safe LIDAR, quantum imaging, and quantum key distribution. These SPADs offer compatibility with Si foundries and potential cost advantages over existing InGaAs/InP devices. However, cooling is necessary to reduce dark-count rates (DCR), which limits photon absorption at 1550 nm wavelength. To address this, we propose integrating a photonic crystal (PC) nano-hole array structure on the Ge absorber layer. While this technique has shown enhanced responsivity in linear Ge detectors, its potential in Ge-on-Si SPADs remains unexplored. Our simulations consider temperature dependence and the impact of electric-field hot-spots on dark count rates. Through these simulations, we have identified means of enhancing single-photon detection efficiency (SPDE) without adversely affecting DCR. We predict significant improvements in performance, including at least a 2.5x enhancement in absorption efficiency.

We propose a method to handle a modulation material with high relative permittivity and suppress electro-optic and spatial disturbances, which causes unexpected modulation of light by using structures formed on the crystal surface. To confirm the effectiveness of the geometric structures on the surface, we prepared three simulation models and calculated the light fields inside the crystals. In these models, pixels were constructed to apply different voltages to individual regions of the crystal. simulations showed that the gap structure and thin film contributed to the generation of phase shaping with a noise lower than the standard. This configuration exhibited efficient modulation, although spatial crosstalk occurred between the two pixels. © 2025 spie.

A four-frame imaging ultra-fast CMOS image sensor for inertial confinement fusion diagnosis is studied. Based on the 0.18 μm standard CMOS technology, the design and simulation of the CMOS image sensor are completed. And the logic reliability of the CMOS imaging sensor based on the in situ pixel division scheme is simulated and verified. The simulation results show that the CMOS image sensor can capture four images at a time, and the time resolution of each image could be controlled at about 300 ps, the frames interval between two adjacent images could be controlled at about 600 ps. © 2024 spie.

This paper aims to improve the post-fabrication transmission performance of nested hollow-core fibers (HCF) by incorporating random perturbations inside the cladding structure in the fiber model and evaluating their impact on the overall guidance performance by applying a Monte-Carlo simulation strategy. Varying silica-wall thicknesses, asymmetric misalignments of the nested and surrounding cladding elements, and anisotropic deformations are investigated and result in loss increases up to 2%, 6%, and 62%, respectively, for fundamental mode propagation at 1.55 mu m. Higher-order modes are affected over one magnitude stronger, although the impact is highly wavelength-dependent, switching dominating effect and mode susceptibility dynamically.
