Design and Simulation of Bragg Grating Based Optomechanical Sensor for Atomic Force Microscopy
Atomic force microscopy (AFM) has been widely recognized as an essential tool that enables the imaging of surface, measuring and localizing many different forces and becoming a standard technique for force spectroscopy at the nanoscale. While conventional AFM is well-developed, recent ... Per saperne di più
Investigation of the Crystalline Lens Inertial Overshooting: Ex Vivo and Simulation Results
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 ... Per saperne di più
Modelling of Thermal Stress in Yb:YAG to Quantify Depolarisation in a Nanosecond 10 J, 100 Hz Laser
The high heat loads intrinsically associated with high-energy, high repetition rate laser systems require sophisticated thermal management analyses to minimise the impact of thermal effects on optical performance. Non-uniform heat deposition in optical elements can lead to the onset of ... Per saperne di più
Multiphysics Design and Analysis of a Refractive Beam Expander and a High-Power Laser
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 ... Per saperne di più
Numerical Simulation-Driven Design of Nanophotonic Biosensors
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 ... Per saperne di più
Polarizability of a Spherical Particle in an Anisotropic Medium
As part of our primary research focus, we explore the phenomenon of non-radiative resonance energy transfer (RET) between a pair of dipoles positioned within a hyperbolic metamaterial (HMM). Our investigation reveals that the presence of an HMM can fundamentally alter these non-radiative ... Per saperne di più
Wavelength Bit-rate Tunable Silicon – Organic hybrid Modulator using commercially Available HLD
On-chip photonic modulators designs currently use NLO material stacks such as LiNbO3 or BaTiO3 on Si or use current injection across silicon waveguides to induce phase change required for optical modulation(Li 2020)(Li 2019). The other silicon compatible option explored is silicon ... Per saperne di più
DESIGN OPTIMIZATION FOR A HIGH SOLAR ACCEPTANCE PLANAR WAVEGUIDE-BASED LIGHT CONCENTRATOR
Solar energy, being the most abundant natural source of renewable energy, will play a crucial role in the ongoing global renewable energy translation. However, energy converted utilization of solar energy, which can be either thermal or electrical, technologies have the limitation of ... Per saperne di più
FEM-based Electrical Analysis of 3D-MOSFET
The fundamental and essential component of the semiconductor electronics industry is the Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The 2D model of MOSFET is widely reported and available in the application library of COMSOL Multiphysics®. However, the 3D model of MOSFET ... Per saperne di più
Mechanistic study of plasmonic photocatalysts through near-electric field simulations
The mechanism of plasmonic photocatalytic systems is still debated as the two major mechanistic pathways, i.e., near-electric field and hot electron transfer for semiconductor photocatalytic systems coupled with small size (dia. < 25 nm) plasmon nanoparticles, are specific to the ...
