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

Rishikesh Datar1, Amogh Patwardhan1, Shreyas Deshpande1, Gautam Bacher1
1Department of Electrical and Electronics Engineering, BITS Pilani K K Birla Goa Campus, Goa - 403726, India.

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

Rabindra Biswas1, Asish Prosad1, Varun Raghunathan1
1Indian Institute of Science, Bengaluru, INDIA

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

Lal Krishna A S1, Jayanta Deka1, Jyothsna K. M. 1, Rabindra Biswas1, Varun Raghunathan1
1Indian Institute of Science

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

Arathy krishna 1, Dr Prita Nair1
1Shiv Nadar University Chennai

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

Swathy R1, Likhith R1, S M Harshitha1, Kaustav Bhowmick1
1PES University, Bangalore, Karnataka, India

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

Ramesh Asapu1, Siegfried Denys2, Sammy Verbruggen2, Silvia Lenaerts2
1IIT Jodhpur, Rajasthan, India
2University of Antwerp, Belgium

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 ...

Polarizability of a Spherical Particle in an Anisotropic Medium

Gaurav Bansode1, Karthik Sasihithlu1
1Indian Institute of Technology Bombay, Powai, India 400076

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

G. Quinn1, M. De Vido1
1Central Laser Facility, STFC Rutherford Appleton Laboratory, Didcot, OX11 0QX, United Kingdom

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
