The results of the feasibility completed at EPFL confirm that the annealing of a thin layer of germanium on silicon makes it possible to obtain an optimal crystalline quality with a flash lamp, by means of the repetition of short pulses, without the diffusion of heat being sufficient to damage the electronic circuits of the […]
Baggage inspection at the airport can be dangerous and time-consuming. The state of the art – currently under assessment – is to use fully automated alarm resolution based on barrier analysis technology to detect explosives and other illicit compounds, such as drugs. The X-ray equipment used comprises a detector, which is particularly expensive and whose detection surface […]
For the detection and characterization of delaminations, a non-destructive testing system for composite (CFRP) aircraft structures can use X-rays. However, this technique is slow and expensive. It is therefore only associated with the use of other means – for example ultrasound and infrared – that it can prove to be effective. The basic project idea consists of […]
One of the goals of IRIS is to develop long-range LiDARs for autonomous vehicles. The core and disruptive technology of the company is the conception of germanium-tin (GeSn) single photon avalanche diodes (SPADs) for short-wavelength infrared (SWIR) sensing. The advantages of the GeSn lie in its high quantum efficiency at wavelengths between 1.5 and 1.6 […]
This is another success! Among seven selected ideas, three come from IRIS. The first concerns a flash LiDAR system operating in the SWIR, the second, a new technology for the detection of delaminations in composite aircraft parts and the third, the inspection of closed luggage for the airport. These feasibility studies will be executed in […]
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.
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% […]
