Investigation of the Crystalline Lens Inertial Overshooting: Ex Vivo and Simulation Results

Ali Dahaghin1, Milad Salimibani1, Agnieszka Boszczyk1, Agnieszka Jozwik1, Damian Siedlecki1
1Department of Optics and Photonics, Wroclaw University of Science and Technology, Wroclaw, Poland

For the purpose of investigation the inertial behaviour of the crystalline lens, the COMSOL Multiphysics® software was used to create a 2D multi-physics model of the porcine eye globe, by using the Fluid-Structure Interaction (FSI). The geometry of the porcine eye model was adapted from ... Read More

Numerical Simulation-Driven Design of Nanophotonic Biosensors

Duc Le1, Jussi Hiltunen1, Alexey Popov1
1VTT Technical Research Centre of Finland, 90590 Oulu, Finland

Optical biosensors are powerful analytical tools for detecting and quantifying biological molecules and particles with high sensitivity and specificity. These devices operate on the principle of detecting changes in optical signals. For example, surface plasmon resonance (SPR) biosensors ... Read More

Multiphysics Design and Analysis of a Refractive Beam Expander and a High-Power Laser

J.B. Accary1
1CILAS, Orléans, France

High power lasers have a wide range of applications. The goal of this work is to analyze and further optimize a beam expander made of 2 lenses used with a kW class laser. The preliminary lens design is performed using an optical design software but its performance analysis, when used ... Read More

Calibration of thermal model to simulate laser assisted bonding process

G. Spinola Durante1, R. Jose James1, E. Rutz Innerhofer1, K. Krasnopolski1
1CSEM, Switzerland

In this poster we present the results of the strategy for calibrating the COMSOL Multiphysics® model to simulate the laser bonding process (LADB) of Mems chips. A specific aspect of this work is to calibrate the COMSOL Multiphysics® heat model loss by measuring with a miniature ... Read More

Simulation of Nonlinear Optical Absorption in Silicon Optical Waveguide

Yaohui Chen1
1Nvidia, Ledreborg Alle 130B, 4000, Roskilde, Denmark

From the perspective of nonlinear silicon photonics, the strong light confinement in sub-micron sized silicon waveguides increases the effective nonlinearity. However, the high optical power density in the waveguide core also increase nonlinear absorption and hence the device self ... Read More

Metamaterial design for ideal solar absorber using multiscale simulations on COMSOL Multi-physics

Dr. Mohamed El Hachemi1, Mrs Nikhar Khanna1, Dr. Guillaume lamblin1, Dr Emanuele Barborini1
1Luxembourg Institute of Science and Technology, Luxemburg

The renewable energy sector faces challenges in production processes due to geo-economic, and environmental issues. This had led to an increased interest in the use of solar energy as an alternative to fossil fuel based energy sources. In the solar energy field, significant research ... Read More

Optimizing and Improving the Intensity Flux in a Reflective Type Laser Focusing system

Rufus Patrick1, Ashok Sharma1
1L&T Defence, India

Abstract. A Laser Focusing system (LFS) focuses a single laser beam (single Channel) or multiple laser beams (multi - channel) onto a surface (Specimen). The general motive of a LFS is to focus a train of brief pulses or a continuous beam of light onto a Specimen which heats up its ... Read More

Optical Performance Assessment of a Solar Collector with a Static Concentrator

J. Goettsche1, S. Alexopoulos1, A. Dümmler1, G. Breitbach1
1FH Aachen, Solar-Institut Jülich, Germany

In this paper a specific version of radiation collecting troughs is investigated. The trough arrangement has a shape which is a combination of a circular arc and adjacent parabolic curve pieces based on a paper by Tripanagnostopoulos [1]. An absorbing tube can be placed at varying ... Read More

FEM modeling of highly strained monocrystalline ZnTe/CdTe core-shell hetero-nanowires

Serhii Kryvyi1, Slawomir Kret1, Dorota Janaszko1, Jakub Plachta1, Piotr Wojnar1
1Institute of Physics, Polish Academy of Sciences, al. Lotnikow 32/46, 02-668 Warsaw, Poland

The monocrystalline semiconductor nanowires (NWs) attract great interest as they reveal new properties that differs from the ones of the bulk equivalents. In addition to small size (10-100 nm diameter), one of their advantages is extremely high surface to volume ratio. This determines ... Read More

Multi-Mirror Array Calculations with Optical Error

J. Goettsche1, S. Alexopoulos1, A. Dümmler1, S. K. Maddineni1
1FH Aachen, Solar-Institut Jülich, Germany

The optical performance of a 2-axis solar concentrator was simulated with the COMSOL Multiphysics® software. The concentrator consists of a mirror array, which was created using the application builder. The mirror facets are preconfigured to form a focal point. During tracking all ... Read More
