Band Diagrams, Bloch Modes and Band Surfaces

CrystalWave features a very advanced and user-friendly Band Structure Analyser, allowing you to calculate band diagrams, Bloch modes and band surfaces for 2D photonic crystal lattices in 2D and 3D, as well as 3D photonic crystal lattices.

Guided Bloch Modes of a Photonic Crystal Waveguide

The modes supported by a photonic crystal waveguide can be solved with CrystalWave's Band Structure Analyser.

A Photonic Crystal Y-junction

Designing a Y-junction in a 2D photonic crystal and modelling light propagation in this waveguide using CrystalWave's FDTD Engine.

Q-Factor Calculator: a Photonic Crystal Cavity

Characterising the Q-factor and resonant wavelength in a photonic crystal cavity using the Q-factor Calculator.

Photonic Crystal Lasers

Simulating photonic crystal lasers and nano-cavity lasers with CrystalWave's Active FDTD Engine.

Nonlinear FDTD: A Photonic Crystal Cavity

Designing and characterising a resonant cavity in a 2D photonic crystal and studying the influence of the nonlinear Kerr effect on the results using CrystalWave's nonlinear FDTD Engine.

Photonic Crystal Optimisation: a Y-Junction (with Kallistos)

Kallistos was used to optimise a photonic crystal Y-junction defined and simulated in CrystalWave with the FEFD Engine, allowing us to obtain lossless power splitting over a wide range of wavelength.

Applications using OmniSim
