Photonic crystal fabrication
WebVarious technologies have been developed for the fabrication of 2D photonic crystal structures. Compared with 3D structures (see below), this is substantially simpler, basically because one has good access to the whole structure from one side and may later on deposit additional homogeneous material, if not simply using an interface to air. ... WebFeb 23, 2024 · The inverse opal photonic crystals (IOPCs) fabricated by etching the SiO 2 spheres from the template composed of poly (ethylene glycol) diacrylate (PEGDA) and SiO 2 within this thin layer (PEGDA/SiO 2) have been fabricated. This process induced a reduction of air sphere diameter lowering to ∼270 nm. This led to a decrease of the average ...
