Review:
Photonic Crystals
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Photonic crystals are optical materials that possess a periodic structure at the wavelength scale, which affects and manipulates the flow of light. By creating variations in refractive index within these materials, they can control electromagnetic waves in ways analogous to how semiconductors modulate electrons, enabling precise control of light propagation and emission.
