Optical fabrication of three-dimensional photonic lattices in LiNbO3:Fe crystals with a single amplitude mask

Optical induction of non-diffracting discrete photonic lattice

“…However, in this way, multi-beam interference must rely on a special and more expensive device. We proposed a simple experimental method to generate multi-beam interference using an amplitude mask with holes [16][17][18][19][20][21] instead of DBS. This method is inexpensive.…”

Photorefractive photonic crystals fabricated with PMMA and 5CB based materials using three-dimensional colloidal crystals

“…Several studies have been conducted on the fabrication of lattice microstructures by using photorefractive materials. 37,38 However, no photonic band gap properties have been discovered or mentioned. On the other hand, tunable photonic crystals fabricated by using 5CB, 27 AzoLC, 25 spiropyran, 39 and lled opals or inverse opals have been reported.…”
