CrystalWave is a design environment that has been created from the ground up for the layout and design of planer photonic crystals.
CrystalWave is the only commercial software that includes a Finite Difference Time Domain (FDTD) Engine, a Plane Wave Expansion (PWE) Engine, a Finite Element Frequency Domain (FEFD) Engine, and an optimizer in one software package.
PC: x86+x64: Win2000/XP/Vista/7, 1GB RAM, 2GHz or better recommended.
CrystalWave provides probably the most powerful, user-friendly graphical user interface for the design of photonic crystals available on the market today.
You can use the mouse to lay out atoms in lattices, point and line defects, quickly and as easily as using a common drawing package; creating with ease even the largest of structures with tens of thousands of atoms.
Numerical input allows fine control of lattice parameters and atom positions, shapes and sizes. You can also use the script system to fully automate the construction of even the most complex structures.
Export your masks and layouts in just a click. CrystalWave allows you to export complete photonic designs to GDS-II with the click of a button, for viewing with third-party GDS-II viewers and for manufacturing.
The following GDS-II features have been implemented to produce a GDS-II file optimized for photonic crystal layouts - substantially reducing file size over a general purpose tool.
The CrystalWave framework includes a highly efficient 2D or 3D FDTD (Finite Difference Time Domain) Engine to simulate the propagation of light through your designs. Independent tests have shown that Photon Design's 3D FDTD Engine to be easily the fastest for many applications and at the same time using much less memory than other implementations
The Cluster Version provides scalable compute power for the FDTD engine. This allows you to solve problems that are too big to run on a single PC, and also to solve problems more quickly.
Photon Design's 3D FDTD Engine has constantly outperformed competing products, usually by a significant margin. The exact performance obtained under cluster operation is dependent on several things such as network bandwidth, domain size, but as a guideline you can typically expect a problem using at least 1GB per node to run better than 90% of the ideal.
The Windows cluster is designed as a convenient ad-hoc clustering setup where unused PCs on your network can be conveniently added to a cluster calculation with little trouble.
The Linux version of the cluster FDTD is designed for more dedicated high-performance cluster use. In this scenario typically the compute nodes are on a private network, inaccessible from designers’ desktop PCs and accessible only through a “head node”. This configuration is shown below.
The Active-FDTD add-on provides additional capabilities to the FDTD Engine to model semiconductor gain. It allows you to model the effect of population inversion to produce optical gain. Now you can at last model photonic crystal and other micro-cavity lasers realistically.
Applications include photonic crystal lasers and VCSELs.
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 mode 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 TE and TM band gaps of your structure and evaluate the Bloch mode profiles at any point.
The FEFD (Finite Element Frequency Domain) Engine is a powerful state of the art 2D Maxwell solver for propagation within an arbitrary photonic structure. The FEFD Engine allows you to compute a steady state (single frequency) response for your device and is the first frequency domain solver that that is capable of solving problems currently only manageable with FDTD methods.
The FEFD Engine is able to perform calculations of complex 2D layouts even orders of magnitude faster than any competing tool.
Photon Design's market leading automatic optimizer is available to drive either the FEFD Engine or the FDTD Engine – together these two tools will reduce design times to a fraction of what is currently possible.
The Kallistos module adds powerful automatic optimization to your CrystalWave design suite. It will save you many hours of design time if not days and will often locate new designs that you are unlikely to obtain manually by trial and error. You can readily find global optima for 3 or 4 parameters of your choice or local optima for 10 or more. Photon Design has used this internally to develop photonic crystal components with world record efficiencies.
