DESIGN OPTIMIZATION FOR A HIGH SOLAR ACCEPTANCE PLANAR WAVEGUIDE-BASED LIGHT CONCENTRATOR nouveau
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 ... En savoir plus
FEM-based Electrical Analysis of 3D-MOSFET nouveau
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 ... En savoir plus
Third harmonic generation from multilayer Van der Waals nanophotonic structure nouveau
Multilayer transition metal dichalcogenides (TMDCs) are an emerging class of dielectric materials with promising applications in modern nanophotonics. They exhibit a much higher refractive index (~ 4 - 4.5) than traditional semiconducting materials like Silicon (~ 3.5) in the near ... En savoir plus
Plane-wave Expansion based modelling of Cassegrain-type Reflective Objective nouveau
Cassegrain-type reflective objectives are widely utilized when performing high resolution infrared optical micro-spectroscopy experiment. Experiments involving the mixing of two or more colors of photons, widely separated in wavelength, greatly benefit from such mirror-based objectives ... En savoir plus
Wavelength Bit-rate Tunable Silicon – Organic hybrid Modulator using commercially Available HLD nouveau
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 ... En savoir plus
Topologically enhanced guided mode resonance sensing of fluid refractive index variations nouveau
The present work explores the integration of guided mode resonance (GMR) structures and topological photonics, characterized by the presence of Jackiw-Rebbi (J-R) solution. The developed surface enhanced GMR structure may serve as a platform for refractive index sensing across various ... En savoir plus
Mechanistic study of plasmonic photocatalysts through near-electric field simulations nouveau
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
