OptiFDTD

OptiFDTD is a powerful, highly integrated, and user friendly CAD environment that enables the design and simulation of advanced passive and non-linear photonic components.

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…

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

NEW VERSION OptiFDTD 13.0

New in OptiFDTD 13.0

In this major release of OptiFDTD we have introduced graphical user interface enhancements and design flow improvements to the…

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…
