The figure of merit is proposed for all-dielectric waveguides for absorption overtone
spectroscopy as the measure of probing efficiency of molecular overtones. It is defined as …

Surface roughness (and more generally) inhomogeneity is a constraining factor on
optoelectronics devices. Its more conspicuous effect is to scatter light thus leading to power …

We developed and tested three MBE-compatible processes for the deposition of high-quality
low-temperature silicon oxides and oxynitrides in the ultra high vacuum at substrate …

We derive simple analytical expressions, using geometric optics, to describe the power
output characteristics of various multimode devices, including acute angle X-junctions …

The authors report the design, fabrication and characterisation of a planar gradient index
(GRIN) PECVD lens. The PECVD-based heilcon plasma reactor was used to deposit graded …

The optical and structural properties of SiO2 films have been studied as a function of the
