What Does PBG Stand For?

PBG stands for Photonic Band Gap

Photonic Band Gap (PBG) refers to a range of wavelengths in which the propagation of electromagnetic waves is prohibited in certain periodic structures, similar to electronic band gaps in semiconductors. This phenomenon occurs in photonic crystals, which are engineered materials that manipulate light through their structural arrangement. PBGs enable various applications in optics and telecommunications, including the development of efficient light sources, waveguides, and sensors by controlling the flow of light in integrated photonic devices.
