Transmissible topological edge states based on Su–Schrieffer–Heeger photonic crystals with defect cavities

Nanophotonics
Topological photonic crystals have great potential in the application of on-chip integrated optical communication devices. Here, we successfully construct the on-chip transmissible topological edge states using one-dimensional Su–Schrieffer–Heeger (SSH ...

Negative Refraction, Subwavelength Lensing Effect and Total Mirror with a Photonic Crystal Structure

Majlesi Journal of Electrical Engineering
We have presented the investigation on the slab of photonic crystals that was made of a honeycomb lattice of silicon embedded in free space. For the simulation of this structure was used the two-dimensional finite-difference time-domain (FDTD) method ...

Wave Propagation through Photonic Crystal Slabs

, 2006
Firstly, we explain the fundamental concepts and the construction of the unconditionally stable method to solve the time dependent Maxwell’s equations. We describe the spatial discretization procedure and the product-formula approach to perform the time integration as well as its stability.
