To overcome the data burden of dual-comb spectrometers, we developed a data processing method for real-time spectra calculation during data acquisition. The spectra retain their envelope structure and the additional RMS-noise can be neglected.

Upconversion (UC) presents a possibility to exploit sub-bandgap photons for current generation in solar cells by creating one high-energy photon out of at least two lower-energy photons. Photonic structures can enhance UC by two effects: a locally in
