Advanced Optical Simulation

The Power of Comprehensive Simulation

Bielcrystal Innovation Technology possesses a full suite of microscopic simulation solutions, from wave optics to Maxwell solvers. This enables us to quantitatively evaluate optical component performance with exceptional accuracy, predicting how light behaves from macro to nano scales.

Wave Optics Simulation

Our wave optics simulation algorithms, based on the Rayleigh-Sommerfeld formula and Huygens-Fresnel principle, model light behavior at the micron scale and its propagation results in free space. This is crucial for understanding diffraction, interference, and beam characteristics in larger optical systems.

Maxwell Solvers for Nanostructures

For sub-wavelength (nanoscale) structures, we employ RCWA (Rigorous Coupled-Wave Analysis) and FDTD (Finite-Difference Time-Domain) algorithms to solve Maxwell's equations. These methods are indispensable for designing and optimizing complex nanophotonic devices and structured optical elements, predicting their interaction with electromagnetic fields.

Example: Nanostructure-based Laser Beam Splitter

RCWA is utilized to simulate the electromagnetic field structure of a nanostructured element designed as a laser beam splitter. The simulation accurately predicts how the nanostructured surface manipulates the incoming laser beam, splitting it into multiple beams with defined angles and intensities. The subsequent free-space propagation of these beams is then modeled to verify the far-field performance.
