What's the difference between a rhombus lattice and a hexagonal lattice in photonics?
I am learning photonic crystal slabs. I try to figure out what the difference between a rhombus lattice and a hexagonal lattice in photonics is?
All I know is that they have diffefent Brillouin zones,...

Refractive Index Ellipsoid for Circular Birefringence Materials
When light travels through an anisotropic medium, its refraction may depend on both its polarization and propagation. Such materials may be classified in terms of their (Linear) Birefringence as ...

A one-dimensional periodic structure is the simplest type of photonics crystal and any such one-dimensional system has a band-gap?
My textbook says the following:
A one-dimensional periodic structure, such as a multilayer film (a Bragg mirror), is the simplest type of photonics crystal, and Lord Rayleigh showed that any such ...

What is the relationship between directions in reciprocal and real space of a photonic crystal?
I am reading "Photonic crystals - molding the flow of light" by Joannopoulos et al. (available on-line). The figures below are reproduced from there.
This is a diagram of a triangular lattice of air ...
