Band Structure Analyser
The analysis of the band structure of a periodic
lattice is a very useful starting point for a photonic crystal circuit
design. In essence it computes the solutions of a structure with
infinite periodicity. This can be a "bulk" lattice but could
also be a line defect, telling you when the lattice is opaque, when a
line defect is single moded and so on.
The Band Structure Analyser will compute the Bloch (periodic) modes of a
photonic crystal lattice with 2 or 3 dimensional periodicity. It will
automatically identify the band gaps of your structure and evaluate the
Bloch mode profiles at any point.
Features:
PWE (plane wave expansion) based engine for best computation in the frequency domain.
2D and 3D simulation modes.
Generates w/k band diagrams for TE-like and TM-like polarisations.
Brillouin-zone constant-omega contour plots.
Easily plot the Bloch modes from any point on the w/k band diagram.
Full integration with the CrystalWave framework
Simple graphical specification of Cartesian and non-Cartesian unit cells.
Supports all lattices definable in the CrystalWave layout editor - rectangular, hexagonal lattices, with square, elliptical or arbitrary shaped "atoms".
Automatic detection of band gaps.
Real and lossy materials.
Calculate effective index, group index and dispersion of the Bloch mode.
Automatic scanners for generation of "band maps" e.g. against lattice period or hole size.
Speed optimised calculation engine takes advantage of any symmetries.
