OptiFDTD Applications

Polarization Splitter with Holey Fiber using OptiMode

Elliptical-hole core circular-hole holey fibers (EC-CHFs) can be engineered to provide absolutely single polarization transmission.

Grating Coupler Design based on SOI Technology

Grating couplers are widely used input/output devices that couple light between fiber (or free-space) and sub-micrometer waveguides. This application note…

Silicon Nanotapers for Fiber-to-Waveguide Coupling

Two approaches for coupling light on a high-confinement chip with sub-micron waveguides are gratings or taper couplers. This application example…

Plasmonic Waveguide Filters with Nanodisk Resonators

Surface plasmon polaritons (SPPs) are waves trapped on the surfaces of metals owing to the interaction between the free electrons in a metal and…

VFEM Accuracy and Advantages

As optical systems move towards an integrated platform, the modelling of high refractive index contrast, sub-wavelength dimension…

Plasmon Polaritons – Vector Finite Element Method

The large negative electric permittivities of noble metals permit the design of sub-wavelength optical guiding structures…

Hollow Core Fiber – Vector Finite Element Method

Hollow core fibers guide light by using a photonic bandgap structure in place of a traditional low index cladding material…

Plasmonic Arrays

Plasmonic nano-hole arrays are an interesting avenue of research because of their highly sensitive transmission properties. Incorporating the already strong light-matter interaction of surface plasmons into a periodic structure allows…

Advantages of 64-bit OptiFDTD

OptiFDTD 64-bit has been thoroughly re-engineered to take full advantage of recent processor and memory evolution…

Surface Plasmon

Suface 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…
