In this case, the Woodpile-Lattice photonic crystal is constructed, and the FDTD solver is used to explore the energy bandstructure of the photonic crystal.

The chemical potential of graphene can be regulated by methods such as voltage or chemical doping. This property makes graphene highly versatile in the field of material-light interactions, particularly in relation to surface plasmon polaritons (SPPs). By exciting surface plasmons, graphene significantly enhances its ability to interact with light.

How to improve Organic solar cells'(OSCs) photoelectric conversion efficiency (PCE) is an urgent problem to be solved. One of the more commonly used methods is to add micro-nano structures for light trapping into the photoactive layer of OSCs to increase light absorption, thereby improving PCE. The photonic crystal (PC) structure is used in the photoactive layer of OSCs, which can enhance the light absorption of solar cells in specific wavelength bands. This case uses FDTD simulation to analyze the light absorption of an OSC with a 2D hexagonal-lattice PC structure.

The ability to modify an object's thermal radiation profile is important in many areas of applied physics and engineering. It has been noted that periodic engineering of devices made of metallic and dielectric materials at the subwavelength scale can change the thermal radiation properties of the device. This case studies the thermal radiation of a photonic crystal obtained by periodically arranging a device made of metallic tungsten and a dielectric material.

Generally, in the simulation of high-Q resonant cavities, the field amplitude obtained is inaccurate. The reason is that the loss rate in the high-Q resonant cavity is slow. If the simulation time is not long enough, the field in the cavity will not decay to 0 at the end of the simulation. At this time, the amplitude of the mode field in the cavity needs to be corrected to obtain the final actual amplitude. This case constructs a photonic crystal resonant cavity structure to demonstrate how to correct the field amplitude when the simulation time of a high-Q resonant cavity is insufficient.

In this case, the optical waveguide model with periodic structure in the propagation axis is constructed, and the bandstructure of the waveguide is analyzed.

In this case, BCC and FCC photonic crystals are constructed and their bandstructures are analyzed using FDTD solvers.

3D Cubic Lattice is a special case of 3D Rectangular Lattice. The lattice spacing of this type of photonic crystal is equal in three axes in space.

In this case, a 2D triangular-lattice PC formed by air cylinders arranged in parallel in the medium is constructed, and its bandstructure is calculated.

Photonic crystals, as a dielectric structure with periodic changes in dielectric constant, can prevent light of a specific frequency from propagating internally, forming a photonic band gap.
