You will only be able to see the first 20 seconds. In particular, the possible existence of a photonic band gap -a range of optical wavelengths that cannot propagate photoniique the structure unless line or point defects are incorporated— provides opportunities for device engineering analogous to semiconductors junctions or heterostructures.

The key feature on reaching unprecedented performances on electric field sensitivities never obtained before come from the fact that the optical detector is an active photonic crystal in which light-matter interaction can be enormously enhanced if a suitable dielectric material is chosen.
Reconfigurable optical add-drop multiplexer pgotonique sets of diffractive elements. Its sensing part does not contain any electronic devices or circuits, so it can easily be miniaturized. Indeed, Photonic crystals PhCs are periodic arrangements of dielectric media that exhibit a photonic band structure that is analogous to the electronic band structure in crystalline solids [JJ08].
