What is Photonic Crystal (PC)?

Photonic Crystals (also known as photonic band-gap materials) are periodic dielectric structures that have a band gap that forbids propagation of a certain frequency range of light.

• This property enables one to control light with amazing facility and produce effects that are impossible with conventional optics.

• Photonic Crystals (PC) are periodic optical/dielectric structures that are designed to affect the motion of photons and consist of separate high dielectric and low dielectric regions.

• The spacing or periodicity determines the relevant light frequencies.
