In our recent work on electrically tunable liquid-crystal Fresnel lenses for optical vortex control, simulation enabled analysis of .phase topology stability, beam propagation, and voltage-controlled optical behavior in real time

. In another study, COMSOL simulations enabled the design of dielectric metasurfaces supporting accidental bound states in the continuum (BICs) for ultra-high-Q chiral sensing. By coupling electromagnetics, nanoscale geometry optimization, and chiroptical analysis, the platform demonstrated near-perfect circular dichroism and strong field confinement for next-generation sensing and bioimaging applications.

At the heart of many advanced photonic technologies lies a complex multiphysics challenge: understanding how optics, electromagnetics, thermal effects, and materials interact simultaneously inside a single device. Without simulation, solving such problems experimentally would require enormous time, cost, and repeated prototyping.
