VFEM Accuracy and Advantages

VFEM Accuracy and Advantages

by Bryan Tipper | Jan 20, 2017 | Applications, Applications, Applications, Latest News, OptiBPM Applications, OptiBPM Applications, OptiFDTD Applications, OptiFDTD Videos, Videos

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

Plasmon Polaritons – Vector Finite Element Method

by Bryan Tipper | Jan 20, 2017 | Applications, Applications, Applications, OptiBPM Applications, OptiFDTD Applications

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....
Hollow Core Fiber – Vector Finite Element Method

Hollow Core Fiber – Vector Finite Element Method

by Bryan Tipper | Jan 20, 2017 | Applications, Applications, Applications, OptiBPM Applications, OptiFDTD Applications

Overview Hollow core fibers guide light by using a photonic bandgap structure in place of a traditional low index cladding material. Since the majority of the optical power propagates through the core air hole region, these fibers are particularly resistant to...
Plasmonic Arrays

Plasmonic Arrays

by Bryan Tipper | Apr 29, 2016 | Applications, Applications, Applications, Background and Tutorials, OptiFDTD Applications, OptiFDTD Videos, Videos

Overview 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 an even greater control...
