Peacock.jl
- or the Plane-wave Expansion Approach to Characterising Optical Crystals in k-space - is a Julia package for studying photonic crystals using the Plane Wave Expansion Method.
Photonic crystals are materials whose optical properties arise from the structuring of the material when the size of the structures are comparable to the wavelengths of light. Peacock.jl
is named for the irridescent colours of peacock feathers which arise not from pigmentation but from their photonic crystal structure, as shown below.

As well as occuring naturally as in animals such as peacocks, advances in nanofabrication mean that 'designer' photonic crystals can now be manufactured for unprecedented control over the flow of light, with applications ranging from optical fibers to photonic circuitry. Photonic crystals are also a promising platform for more exotic materials like topological insulators.
