Combination of multiple QCLs is an elegant way to harness to beneficial properties of the emitted light of single QCLs and expand the accessible wavelength and/or power regime.
UULM (Ulm University, Institute of Analytical and Bioanalytical Chemistry) develops and investigates in close cooperation with art photonics GmbH, nanoplus Nanosystems and Technologies GmbH and OptoPrecision GmbH the characteristics, capabilities and suitability of different beam combining concepts for the intended purpose within the MIRACLE project.

First generations of fiber optics, reflective optics as well as dielectric waveguides are designed, evaluated, optimized and utilized for beam combining. Conceptual design, optimization thereof and realization of the final devices is realized by UULM.
