Leaky Modes in a Microstructured Optical Fiber

Application ID: 88741

A mode analysis study is used to find the complex effective indices for a microstructured optical fiber (MOF), consisting of air holes in a silica host. As the effective index is smaller than the refractive index of the silica background material, the modes are leaky.

The model demonstrates both the use of a perfectly matched layer (PML) and the use of the Scattering boundary condition to truncate the simulation domain.

The real and imaginary parts of the effective index compare well to values from a published paper.

This model example illustrates applications of this type that would nominally be built using the following products:
