Optimization of plasmon–plasmon coupling in photorefractive layered media [PDF]
In this paper we study grating-induced plasmon–plasmon coupling in photorefractive layered media using a weakcoupling approximation. The method used is applicable to general layered structures that support both plasmonic and optical modes, such as ...

Quantitative determination of charge transfer parameters of photorefractive BaTiO3 : Rh from EPR-based defect studies [PDF]
Optical absorption bands can be used as fingerprints of defects and their charge states in insulators and semiconductors. On the basis of the photochromicity usually shown by such materials, a method is introduced by which the optical bands are assigned ...

Amplification of near-infrared light in a photorefractive ring resonator [PDF]
We have demonstrated efficient amplification of near-infrared, 0.83-0.7µm and 1.06-1.07µm light, in a photorefractive ring resonator using Rh:BaTiO3. The optical power oscillating inside the ring exceeded the pump power by a factor of up to 2.34.

TOPOGRAPHY-GUIDED PRK FOR IRREGULAR ASTIGMATISM CORRECTION IN KERATOCONUS PATIENTS
Purpose. To evaluate the efficacy of topography-guided photorefractive keratectomy (PRK) performed using the MicroScan Visum excimer laser (Optosystems, Russia) after intrastromal corneal ring segment (ICRS) implantation and collagen cross-linking (CXL ...
