Semiconductor photonic crystals

Semiconductor photonic crystals are specially designed materials with a periodic structure that manipulates how light travels through them. By arranging tiny components in regular patterns, they can control, reflect, or guide specific wavelengths of light precisely. These structures are used in advanced optical devices, such as lasers, sensors, and communication systems, because they can enhance light-matter interactions and improve performance. Essentially, they function like optical filters or waveguides built into semiconductor materials, enabling more efficient and miniaturized photonic technologies.
