High-power whitelight source with tuneable polarization-maintaining fiber output

The fiber-coupled high-power white-light source by NKT is employed for the holistic characterization of the optical properties of laser-written waveguide systems with high spectral resolution and large bandwidth. As “circuitry for light”, functionalized waveguides constitute the building blocks of integrated photonic devices. In conjunction with precisely characterized laser-induced micro- and nanostructures for the local modification of the host material, they enable all degrees of freedom of photons to be harnessed for classical as well as quantum-optical applications on a chip.

Future fields of applications of this white-light source will be the fine-tuning and tailoring of quantum-optical circuits, the calibration of novel sensor systems based on integrated-optical arrangements, and the systematic extension of their accessible spectral range from blue far into the infrared region. In addition to these manifold technological scenarios, this purchase paves the way for future projects as well as the intensification of existing scientific collaborations.

The purchase of this positioning system was financially supported by the state of Mecklenburg-Vorpommern via the European Regional Development Fund (ERDF), programming period 2018-2019.
