Highly accurate determination of propagating and
leaky modes
Complete control of structure
Fast simulation time
Simple, flexible design environment
Product Description
HALO is an advanced, easy-to-use simulation tool for the analysis
and design of micro-structured optical fibers. The design of micro-structured
fibers has been impeded by the lack of dependable methods for
calculating the propagating modes. HALO utilizes highly accurate
Fast Multipole Methods (FMMs) in order to achieve errors of one
part in a million with modest computational effort. The results
are obtained faster and more easily than with existing methods.
The designer can work with hole structures of unlimited geometric
complexity. with confidence that the resulting calculations are
resolved solutions of the full set of Maxwell equations.
The
graphical user interface is flexible and powerful. You can import
the cross-section of a micro-structured fiber from a simple ASCII
file format, use a variety of drawing tools and "wizards"
in our graphical user interface, or modify a sample from our internal
library.
Our algorithms are data-driven. All you specify in the design
phase is a set of smooth boundaries defining the regions with
distinct refractive indices. Once the geometry is specified and
a wavelength regime is chosen, the propagating modes are calculated
with the click of a mouse button. The solvers are "black-box",
require no mesh generation, and (unlike conventional methods),
do not lose accuracy when the index contrast is sharp and large.
HALO returns the dispersion curves, as well as graphical representations
of the field intensity for any of the desired modes.
The
