Glass-based 1D photonic crystals and planar waveguides are fabricated by the rf-sputtering technique on different substrates, such as Poly(methyl methacrylate) (PMMA), Polyether ether ketone (PEEK), SCHOTT AS 87 eco ultra-thin glass and SiO2. The optical, spectroscopic and structural features of the samples are measured and compared before and after mechanical deformation. The planar waveguide SiO2-HfO2:Er3+ deposited on PEEK and on ultra-thin glass present an attenuation coefficient lower than 0.3 dB/cm at 1542 nm and emission at 1.5 m characteristic of Er3+ ions in an amorphous environment.

RF magnetron sputtering deposition of multilayers optical filters for ultra-broadband applications with a large number of thin layers

CIMAP, France

We present recent achievement on manufacturing optical filter and multilayers done with two complementary RF magnetron sputtering approaches: deposition duration control and in situ optical reflectance monitoring. Those approaches have been greatly improved thanks to ellipsometry and spectrophotometry cross-studies of optical refractive indexes of Nb2O5, TiO2 and SiO2 materials grown using two sputtering systems. At the same time, we conducted deposition studies of these three materials which have increased the manufacturing reliability and allow us to consider developing complex optical multilayers with more than 100 sub-layers

Optical properties of ALD-deposited ZrO2 thin films: the refractive index and photoluminiscence

The optical properties of amorphous ALD-deposited zirconium oxide were studied in terms of its refractive index and photo-induced luminescence ability. We infer that the oxygen vacancies and nitrogen impurities may be the origin of the luminescence of these films.

Key assets for transparent electric contacts in optoelectronic applications are high conductivity and large transparency over extended spectral range. Indium-Tin-Oxide and Aluminium-doped-Zinc-oxide are commercial examples, with their electrical conductivity resembling those of metals, despite, their transparency being limited up to 1.5um. This work introduces smooth and compact amorphous thin films of n-type semiconducting WO3-x prepared by RF-sputtering followed by annealing in dry air, as optical layers of tailorable dielectric properties. We evaluate Figure of Merit, combining electrical conductivity and optical transparency, and rate the performances as a transparent conductive layer.

Ammonia gas sensing via whispering gallery mode resonator

The concentrations of ammonia gas has been measured using a whispering gallery mode (WGM) resonator based sensor. The resonances in the WGM resonator experience a shift in presence of gas molecules. This shift can be drastically increased by adding a new porous layer on the resonator surface. In that case the porous layer acts as “trap” for the gas molecules and moreover changes the refractive index of the surrounding medium.
