Proposed legislation aimed at securing a reliable supply of materials essential to the optics and photonics industry has received support from SPIE, the international society for optics and photonics....
First Experimental Evidence of a ?ovel Multimode Pumping Scheme for an Array of Rare-earth Doped Waveguide Amplifiers and Lasers
ovel Multimode Pumping Scheme Rare-earth Doped Waveguide Amplifiers Lasers
2015/6/8
We propose a novel multimode pumping scheme for waveguide amplifier and laser arrays. Light from a broad area laser at 980 nm is coupled into a large passive waveguide and then effectively transferred...

Light Emission Rare-Earth Doped Silicon Nanostructures
2009/5/19
Rare earth (Tb or Ce)-doped silicon oxides were deposited by electron cyclotron resonance plasma-enhanced chemical vapour deposition (ECR-PECVD). Silicon nanocrystals (Si-ncs) were formed in the silic...
Guided mode properties of rare-earth doped photonic crystal fibers are investigated as a function of the core refractive index, showing the possibility to obtain cutoff at low normalized wavelength.
Near-infrared luminescence of rare earth ions in oxyfluoride lead borate glasses and transparent glass-ceramic materials
