Erbium - ytterbium - yttrium compounds for light emission at 1
Silicon microphotonics has emerged as the leading technology to overcome the interconnect bottleneck that limits a further increase of computation power following Moore's law. Optical interconnects between different electronic microprocessors in an electronic-photonic integrated circuit (EPIC) can provide a fast, low-loss and highbandwidth alternative to electrical interconnects, which suffer f...
متن کاملSurface-Directed Synthesis of Erbium-Doped Yttrium Oxide Nanoparticles within Organosilane Zeptoliter Containers
We introduce an approach to synthesize rare earth oxide nanoparticles using high temperature without aggregation of the nanoparticles. The dispersity of the nanoparticles is controlled at the nanoscale by using small organosilane molds as reaction containers. Zeptoliter reaction vessels prepared from organosilane self-assembled monolayers (SAMs) were used for the surface-directed synthesis of r...
متن کاملTHE SYNTHESIS, CHARACTERIZATION, AND UPCONVERTING PROPERTIES OF ERBIUM DOPED; YTTERBIUM, ERBIUM CO-DOPED YTTRIUM OXYSULFIDE PHOSPHORS UNDER 808, 980, AND 1560 nm EXCITATION
Bulk yttrium oxysulfide phosphors were prepared using the polysulfide flux method. The morphology and structure was characterized using transmission electron microscopy and x-ray powdered diffraction. Visible emissions occurring near 530 and 550 nm and 660 670 nm consistent with the H11/2, S3/2 → I15/2 and F9/2 → I15/2 transitions, respectively, were observed under 808, 980, and 1560 nm excitat...
متن کاملMultiple minimally invasive Erbium: Yttrium Aluminum Garnet laser mini-peels for skin rejuvenation: an objective assessment.
BACKGROUND As the demand for minimally invasive rejuvenation is increasing, micropeel resurfacing using Erbium:Yttrium Aluminum Garnet (Er:YAG) laser 2940 nm has been reported for the treatment of photoaged skin without ablation of the epidermis. However, little is known about the efficacy and underlying histologic changes associated with this type of treatment. AIMS The aims of this study ar...
متن کاملCoupling of erbium dopants to yttrium orthosilicate photonic crystal cavities for on-chip optical quantum memories
Erbium dopants in crystals exhibit highly coherent optical transitions well suited for solid-state optical quantum memories operating in the telecom band. Here we demonstrate coupling of erbium dopant ions in yttrium orthosilicate to a photonic crystal cavity fabricated directly in the host crystal using focused ion beam milling. The coupling leads to reduction of the photoluminescence lifetime...
