Welcome to the Website of the
11th European VCSEL Day 2018 Workshop
in Ulm on April 12−13

The vertical-cavity surface-emitting laser (VCSEL) business is booming more than ever. A record number of devices is being produced worldwide for traditional and young market segments. Time-of-flight sensing for gesture recognition and infrared illumination for 3-D imaging in smartphones are prominent examples. The 11th VCSEL Day will provide a European forum to discuss the state of the art and present latest research results: novel device concepts, performance records, inexplicable effects, new application ideas – contributions on all VCSEL-related topics are most welcome!
