In-situ etch-depth control better than 5 nm with reflectance anisotropy spectroscopy (RAS) equipment during reactive ion etching (RIE): A technical RAS application

open access: yesAIP Advances, 2019
A measurement technique, i.e. reflectance anisotropy/difference spectroscopy (RAS/RDS), which had originally been developed for in-situ epitaxial growth control, is employed here for in-situ real-time etch-depth control during reactive ion etching (RIE ...

Enhanced Far-Field Directional Luminescence Emission by a Hybrid Structure Consisting of Silver Channel and Microlens

open access: yesIEEE Photonics Journal, 2019
In microfluidic detection, the distance between the fluorescent nanoparticles (FNPs) and the structure is usually in far-field range. In previous work, the enhancement of emission will decay exponentially with the increase of the distance between FNPs ...

Double tungstate lasers: From bulk toward on-chip integrated waveguide devices [PDF]

open access: yes, 2007
It has been recognized that the monoclinic double tungstates $KY{(WO_4)}_2$, $KGd{(WO_4)}_2$, and $KLu{(WO_4)}_2$ possess a high potential as rare-earth-ion-doped solid-state laser materials, partly due to the high absorption and emission cross sections ...
