Stray light represents a significant challenge in a wide range of photodiode and photodiode array applications, as it elevates the background signal, reduces detector sensitivity, and degrades the signal-to-noise ratio. Traditional approaches to mitigate stray light, such as blackening ... En savoir plus

Gallium nitride (GaN) power modules are increasingly adopted in applications such as electric vehicle on-board chargers, due to their lower power loss and higher switching speed. To enhance power density and reduce parasitic inductance, modern packaging solutions are being developed ... En savoir plus

In modern optical systems, such as those used in automotive cameras, aerospace sensors, and surveillance equipment, optical windows serve as protective layers while allowing light to pass through. These windows must maintain high transmittance and simultaneously preserve image quality. ... En savoir plus

High average power lasers with increased efficiency are a crucial development required for achieving inertial confinement fusion as a viable energy source. For high average power, the thermal management and its influence on laser beam quality strongly effect the final focusability on ... En savoir plus

As semiconductor devices continue to shrink and incorporate complex 3D architectures, conventional optical metrology faces limitations in resolving features smaller than the optical wavelength or those hidden beneath opaque layers. Ultrafast photoacoustic spectroscopy provides a ... En savoir plus

The integration of plasmonic components into optoelectronic platforms enables promising pathways for high-speed, ultra-compact signal modulation at the nanoscale. In this work, we present a novel all-plasmonic modulator, which leverages localized surface plasmon resonance (LSPR)-induced ... En savoir plus

Pleural photodynamic therapy (PDT) represents a promising treatment approach for malignant pleural mesothelioma. However, optimizing treatment efficacy requires accurate prediction of reactive oxygen species ([ROS]rx) distribution, which is challenging due to complex cavity geometries ... En savoir plus

Abstract for COMSOL Conference With the world continuously scaling MOSFETs into smaller submicron dimensions, subthreshold current and threshold voltage control are important challenges to ensure optimal device performance. This study explores the effects of halo implants on simulated ... En savoir plus

Surface plasmons in metal rectangular gratings can form bands and band gaps in their dispersion relations, analogous to those in photonic band-gap crystals and electronic bands in semiconductors. Introducing a dielectric coating atop the metal redshifts the plasmonic band gap, enabling a ... En savoir plus
