Feasibility Study Completed with Success !

New sensing technology of delamination in composite aircraft parts [Idea 2/3 selected by the Microtech Booster (4th loop)]

By using a new perovskite detector the project team could successfully demonstrate the advantages of this technology for the inspection of composite aircraft parts. Optimization runs are on-going in order to reduce further the lead-time of this non-destructive […]

Idea selected by the Microtech Booster (5th loop): GeSn Photodetectors on Si Substrate for Gas Detection

This new project selected by the Microtech Booster (https://microtechbooster.swiss/) is focused on sensitivity tests of an innovative, low cost SWIR photodetector for gas sensing applications. The feasibility study will be performed with the contribution of high-class entities such as AXETRIS (spectrometry), VERTILAS (laser) and EPFL (photodetector).

A broadband light source, a multipath gas chamber with […]

Innovation Cheque

The Swiss Innovation Council “Innosuisse” has approved our funding application entitled “MoCA”. This preliminary study will be performed with HE-Arc to demonstrate the feasibility of an effective photon detection at short-wave
infrared (SWIR) wavelengths for smartphones and consumer (AR/VR) applications. The device set-up basically comprises a germanium-tin (GeSn) single-photon avalanche diode (SPAD) array as receiver and […]

Microtech Booster (3rd loop): What’s Next?

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 […]

Idea 3/3 selected by the Microtech Booster (4th loop): New Detection Technology for Airport Closed Luggage Inspection

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 […]

Idea 2/3 selected by the Microtech Booster (4th loop): New sensing technology of delamination in composite aircraft parts

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 […]

Idea 1/3 selected by the Microtech Booster (4th loop): Solid state flash LiDAR for mid-range 3D detection

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 […]

New Ideas selected by the Microtech Booster (4th loop)

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 […]

Idea selected by the Microtech Booster (3rd loop)

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 Production of Photodiodes

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.
