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.

THz Spectroscopy of GeSn-on-Ge Samples

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% […]

LiDAR Modelling Results

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 […]
