BandSOLVE is a design tool to automate and simplify the modeling and the calculation of photonic band structures for all photonic crystal devices.
- BandSOLVE employs a powerful Plane Wave Expansion algorithm for the solution of one-, two, and three-dimensional photonic bandgap devices.
- BandSOLVE includes several advanced simulation features that allow for more efficient band computations.
- For many types of devices, the inversion symmetry can be enforced leading up to a 40% increase in speed.
- Mode seeding can be utilized to dramatically increase the speed of the calculations.
- In 3D calculations, parity can be included for the separation of even and odd modes.
- BandSOLVE can be used to optimize the band structure of new photonic crystal geometries before fabricating the device and to determine the performance of existing components.
- Two-dimensional and three-dimensional PC slab and waveguides
- Two-dimensional and three-dimensional cavity problems
- Photonic Crystal Fibers, both band-gap guiding and conventional guiding
- Defect modes of non-strictly periodic structure
- Metallic and anisotropic structures

Band Structure Analyzer
Commercial software (part of CrystalWAVE) sold by Photon Design.
The Band Structure Analyzer computes the Bloch (periodic) modes of a photonic crystal lattice with two or three dimensional periodicity. It automatically identifies the band gaps and evaluates the Bloch mode profiles at any point.
- Plane wave expansion based engine for best computation in the frequency domain
- Two- and three-dimensional simulation modes
- Generates w/k band diagrams for TE-like and TM-like polarizations
- 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 optimized calculation engine takes advantage of any symmetries

MIT Photonic-Bands (MPB)
Free software developed by MIT group.
MPB is a free program for computing the band structures (dispersion relations) and electromagnetic modes of periodic dielectric structures, on both serial and parallel computers.
- Computes definite-frequency eigenstates (harmonic modes) of Maxwell’s equations in periodic dielectric structures for arbitrary wavevectors
- Fully-vectorial and three-dimensional methods are implemented
- Preconditioned block-iterative eigensolvers in a planewave basis are used
- Sharp material discontinuities can be handled and convergence proportional to the square of the spatial resolution can be achieved even for sharply discontinuous anisotropic dielectric structures
- Photonic crystals
- Optical waveguides and resonator systems
- Waveguides with arbitrary cross-sections
- Anisotropic or magnetic materials

Waveguide Mode Solver
A waveguide mode solver is based on a two-dimensional plane-wave expansion method which includes gain and losses.
- The first version employs analytical integration while the second version uses a numerical integration. It is limited to not too complex situation, because of the complexity of the analytical integration of piecewise defined functions.
- The numerical version is capable to treat reasonable large scale problems.
