At the end of the 3rd loop of the Microtech Booster (https://microtechbooster.swiss), the idea presented by IRIS was selected. The ultimate ambition of the project is to produce a system for the simultaneous detection of X-rays and short-wavelength infrared (SWIR), mainly for improving the inspection of composite aircraft structures or controlling the quality in […]

First germanium-tin (GeSn) photodiodes operating in the short-wave infrared (SWIR) – in a row of 4 pixels, each comprising 4 SPADs – were fabricated at EPFL. They are currently being characterized at The Quantum Technology Group, Geneva University.

The HE-Arc Engineering team – with support of our friends at APTASIC – produced the first packaging of our detector. For testing purposes, it contains a high performance Peltier module.

IRIS has adopted with success Silvaco TCAD simulation software to prove the fabrication feasibility of a short-wave infrared single photon avalanche diode. [Link to Silvaco Press Release]

THz spectroscopy studies performed at Manchester University on GeSn-on-Ge samples show good results in terms of carrier lifetime and mobility. These values confirm the excellent performance of the GeSn alloy, even with a low fraction of Sn. In particular, with 3% […]

The feasibility of a flash LiDAR for autonomous ground vehicles could be demonstrated by simulations. The main conclusion may be summarized as follows:  the combined effect of the coincidence method and the 3 times higher quantum efficiency of the Ge0.98Sn0.02 alloy @ 1550nm compared to pure Ge, means that the maximum laser power can be […]
