(Universidade Federal de São Paulo (UNIFESP), 2016-11-11)
The research of nanostructured super hard materials in the form of coatings or thin films with advanced properties has enabled the development of new studies providing important scientific and technological developments ...
All-optical switching device for infrared based on PbTe quantum dots
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
Multilayers of PbTe quantum dots embedded in SiO2 were fabricated by alternate use of Pulsed Laser Deposition (PLD) and Plasma Enhanced Chemical Vapor Deposition (PECVD) techniques. The morphological properties of the ...
a-SiC : H anti-resonant layer ARROW waveguides
(IOP PUBLISHING LTD, 2008)
Over the last decades, anti-resonant reflecting optical waveguides (ARROW) have been used in different integrated optics applications. In this type of waveguide, light confinement is partially achieved through an anti-resonant ...
