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 demonstrates the operation of a nanotaper for fiber-to-waveguide coupling based on Silicon-on-insulator (SOI) technology....
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 the electromagnetic field in a dielectric. This application note demonstrates the concept of multi-channel wavelength...
VFEM Accuracy and Advantages
Overview As optical systems move towards an integrated platform, the modelling of high refractive index contrast, sub-wavelength dimension waveguides becomes more important. These properties require a mode solver that can both faithfully approximate the geometry and...
Plasmon Polaritons – Vector Finite Element Method
Overview The large negative electric permittivities of noble metals permit the design of sub-wavelength optical guiding structures. In particular, the negative permittivity allows guided modes to exist at single interfaces between the metal and a positive dielectric....
