Axial optical trapping efficiency through a dielectric interface
(Amer Physical SocCollege PkEUA, 2007)
Erbium-activated HfO2-based waveguides for photonics
(2003-12-01)
70SiO2 - 30HfO2 planar waveguides, activated by Er3+ concentration ranging from 0.3 to 1 mol%, were prepared by solgel route, using dip-coating deposition on silica glass substrates. The waveguides showed high densification ...
