Ultra-low background experiments based on the so-called phonon-light technique (e.g., direct dark matter search experiments such as CRESST and EURECA or future experiments searching for the neutrino-less double beta decay such as CUPID) rely heavily on the sensitivity of the cryogenic light-detector at low light energies. The Neganov-Trofimov-Luke effect (NTLE) offers a promising way to increase the sensitivity of cryogenic light detectors by drifting photon induced electron-hole pairs in an electric field, thereby amplifying the heat signal in the cryogenic detector. In this contribution we present an overview and results of the current status of our detector development efforts as well as potential applications and planned future developments.
