Suface Plasmon

Surface Plasmon

Surface plasmons are waves that propagate along the surface of metallic and certain dielectric materials. The electric field of a plasmon wave reaches its maximum at the surface and decays evanescently away from the surface. The wave properties are highly sensitive to any changes in the refractive index of the material as well as the device’s geometry. As a full wave modeling method…

FDTD - Diffraction Grating 3D Layouts

Diffraction Grating

Finite-Difference Time-Domain (FDTD) is a powerful numerical method for simulating diffraction gratings, where the grating element and working wavelength are close in size. With OptiFDTD, the incident wave can be versatile and best matched with the real application; the CAD tools enable us to design different types of grating layouts; the simulated near field pattern…

FDTD - Photonic Crystal Layout

Photonic Crystal

OptiFDTD provides two simulation engines for modeling photonic crystal devices and corresponding defects: 1) 2D and 3D FDTD simulation to study the field response and transmission/reflection spectrum; 2) PWE method to perform ban-diagram analysis for 1D, 2D and 3D photonic crystal devices.

Nanoparticle

Using OptiFDTD the transmission spectrum of a gold nanoparticle can be calculated. The simulation can begin using a 64-bit calculation engine where the user can only see a progress bar which allows us to cut down on CPU and memory overhead which is critical for running larger designs.

Silicon Nanowire for Photovoltaic Applications

(PVs) are arrays of cells containing a Solar photovoltaic material that converts solar radiation into direct current electricity. Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, microcrystalline silicon, cadmium telluride, and copper indium selenide/sulfide.

Nano-Lens and Micro-Lens Simulations

When optical lens size is compatible with the working wavelength, the traditional lens analysis tools such as ray-tracing method will lose their accuracy. The FDTD method can be used to advantage in the nano-lens simulation. OptiFDTD software also provides tools so that beam focus size, focus distance, and far-field transform can be obtained directly.

Light Scattering from Single Biological Cells

Biological cells can be considered as dielectric objects with a given refractive index distribution. Light scattering simulations provide us with an efficient tool for studying cell morphology as well as the nature of scattering and its sources.
