Optical Microsystems

CMST is creating solutions for the photonics packaging challenges in datacom, telecom and sensing. We are developing technologies to facilitate interfacing of photonic integrated circuits both optically (integration of optical coupling structures) and electrically (integration of drivers).

In addition, CMST has built up a technology platform allowing photonics integration of optical waveguides, coupling structures, light sources, detectors, and electronic circuitry on rigid, flexible, and stretchable substrates targeting a variety of medical or optical sensing-related applications. Together with our partners, we are particularly working towards soft and flexible waveguide probes for optogenetics and flexible wearable photonic patches with miniature lasers and detectors for medical diagnostics.

Laser technology has since long been an important competence, and the group has several laser systems at its disposal: a KrF Excimer laser, ND YAG laser and CO2 laser for drilling microvias and structuring materials and a picosecond and femtosecond laser for advanced material processing and glass modification. Using the femtosecond laser, we realize optical waveguides, sensors and microchannels using direct writing in glass for applications in photonics packaging and sensing. Based on the picosecond laser, we develop technologies for laser transfer printing of chiplets for high-speed precision assembly.
