Erbium-doped planar optical device
TLDR
In this paper, a method for forming an active optical device, including the step of depositing an erbium-doped active core by sputtering, is presented, and the active core does not contain significant amounts of alkali metals or alkaline earth metals but does contain at least two modifier metals.Abstract:
An active optical device comprises a glass, waveguiding structure disposed on a substantially planar principal surface of a substrate. The structure includes a silica-based, erbium-doped active core. The active core has an absolute erbium concentration of at least about 0.5×1020 atoms per cubic centimeter, and a radiative lifetime of the erbium lasing level of at least about 5 milliseconds. The active core does not contain significant amounts of alkali metals or alkaline earth metals but does contain at least two modifier metals. Also disclosed is a method for forming an active optical device, including the step of depositing an erbium-doped active core by sputtering.read more
