Design of 160-Channel Si3N4 based AWG-Spectrometer for Medical Applications

Seyringer D., Burtscher C., Edlinger J., Maese-Novo A., Muellner P., Hainberger R., Kraft J., Koppitsch G., Meinhardt G., Sagmeister M., Vorarlberg University of Applied Sciences, AT

We present the design of 160-channel, 50-GHz Si3N4 based AWG applying our proprietary AWG-Parameters tool. For the simulations of the AWG layout, we used PHASAR photonics tool from Optiwave. The simulated transmission characteristics were then [...]

Solar battery program in Austria – innovative solutions for increasing solar coverage

Egger C., OO Energiesparverband, AT

Upper Austria is one of Austria’s nine federal states with a population of 1.4 million. It located in the northern part of the country, bordering Germany and the Czech Republic. Since the mid-90s, the government [...]

Application of Angular Method to Correct Channel Spacing Between AWG Demultiplexed Channels

Seyringer D., Vorarlberg University of Applied Sciences, AT

Arrayed Waveguide Gratings (AWGs) offer an attractive DWDM solution because they are a very compact way to provide for higher channel count solutions, have good performance characteristics, and can be more cost effective per channel [...]

Local Synthesis of CuO Nanowires on CMOS Microhotplates for Gas Sensing Applications

Steinhauer S., Maier T., Mutinati G.C., Rohracher K., Siegert J., Schrank F., Koeck A., Materials Center Leoben Forschung GmbH, AT

CuO nanowires are locally synthesized on CMOS microhotplates leading to the realization of functional gas sensing devices. Only approximately 20mW are needed in order to heat the CMOS microhotplates to a temperature around 350°C, which [...]

In vitro biosensing based on magnetically induced motion of magnetic nanoparticles

Dangl A., Kokkinis G., Keplinger F., Giouroudi I., Vienna University of Technology, AT

A method for in-vitro detection of bioanalyte using conductive microstructures to accelerate magnetic nanoparticles (MAPs) in an integrated microfluidic system is presented. The fundamental idea behind the elaboration of such a biosensing system is that [...]

Correlated statistical SPICE models for High-Voltage LDMOS Transistors based on TCAD statistics

Seebacher E., Steinmair A., austriamicrosystemsAG, AT

Accurate process variation coverage within SPICE models has become an essential demand from the design community. These variations can be simulated most efficiently with statistics based models which avoid unrealistic pessimistic corners. Sufficient measurement data [...]

Gas sensor device based on a SnO2 nanowire network for increased sensing performances

Brunet E., Mutinati G.C., Steinhauer S., Koeck A., AIT Austrian Institute of Technology GmbH, AT

A novel gas sensor device based on a network of tin dioxide (SnO2) nanowires is presented. The high surface-to-volume ratio presented by the network of ultralong nanowires enables increased gas sensing performances in comparison to [...]

High-Voltage MOSFET Compact Modeling

Seebacher E., austriamicrosystems AG, AT

In many new applications like communication and automotive electronics the usage of integrated high voltage MOS transistors (LDMOS and DMOS) requires highly accurate compact models. At first we discuss the industrial requirements for modern high [...]

Performance Study of Nitride-Based Gunn Diodes

Aloise G., Vitanov S., Palankovski V., Advanced Material and Device Analysis Group, AT

In this work, we assess the performance of InN Gunn diodes, as a superior alternative to GaN. We perform two-dimensional mixed-mode device/circuit simulation accounting for self-heating effects. We verify available theoretical results for GaN-based Gunn [...]
