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.
We love to identify new applications areas of VCSELs, e.g. in optical sensing and metrology, biophotonics, ...
If you like to discuss your ideas, please don't hesitate to contact us.

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.
