VCSELs and Optical Interconnects
At present, our activities are focused on various optoelectronic devices, a new modulation format for optical data transmission, 3-D imaging, and optical sensing. More in particular, we are working on
- novel VCSEL designs, in particular the monolithic integration of phototransistors for optically controlled current confinement,
- spintronic VCSELs with high and tunable birefringence for future polarization modulation schemes,
- a new time-of-flight-based method for depth imaging using VCSEL illumination,
- as well as refractive index sensing with VCSEL-related resonant devices.
The VCSEL Group organized the 11th European VCSEL Day 2018 Workshop that was held in Ulm on April 12−13:

A great deal of our work is being performed in the excellently equipped cleanroom of Ulm University.
We enjoy a fruitful collaboration with Philips Photonics, which emerged as "U-L-M photonics" from the VCSEL group in the year 2000 and which is one of the world leaders in VCSEL fabrication.
