Next generation bolometric experiments, such as CUPID, are demanding for very competitive cryogenic light detectors. The technology for light detection must ensure an RMS noise resolution lower than 20 eV, a wide active surface (several cm2) and a high intrinsic radio-purity. Furthermore, the detectors have to be multiplexable, in order to reduce the number of electronics channels for the read-out, as well as the heat load for the cryogenic apparatus. Finally they must be characterized by a robust and reproducible behaviour, as next generation detectors will need hundreds of devices. None of the existing light detectors satisfies all these requests. In this contribution I will present the CALDER project, a recently proposed technology for light detection which aim to realize a device with all the described features.
