De Vita, Christian (author), Klitis, Charalambos (author), Codreanu, N. (author), Ferrari, Giorgio (author), Sorel, Marc (author), Melloni, Andrea (author), Morichetti, Francesco (author)This work reports on the realization of an amorphous silicon visible-light detector integrated in Si3N4 waveguides. The device is very compact (< 40 μm), has a responsivity of about 10 mA/W and a sensitivity of -40 dBm.conference paper 2022

Ferrari, Lorenza (author), Yurduseven, O. (author), Llombart, Nuria (author), Yates, Stephen J.C. (author), Bueno, Juan (author), Murugesan, Vignesh (author), Thoen, David (author), Endo, A. (author), Baryshev, AM (author), Baselmans, J.J.A. (author)Next generation sub-mm imaging instruments require kilo-pixel focal plane arrays filled with background limited detectors. Microwave kinetic inductance detectors (MKIDs) are a state-of-the-art detector for future instruments due to their inherent multiplexing capabilities. An MKID consists of a superconducting resonator coupled to a feed-line...journal article 2018

Teixeira, Andre M.H. (author), Ferrari, Riccardo M.G. (author)In this paper, the problem of detecting stealthy false-data injection attacks on the measurements is considered. We propose a multiplicative watermarking scheme, where each sensor’s output is individually fed to a SISO watermark generator whose parameters are supposed to be unknown to the adversary. Under such a scenario, the detectability...conference paper 2018

(author), Yates, S.J.C. (author)An integrated filterbank (IFB) in combination with microwave kinetic inductance detectors (MKIDs), both based on superconducting resonators, could be used to make broadband submillimeter imaging spectrographs that are compact and flexible. In order to investigate the possibility of adopting an IFB configuration for DESHIMA (Delft SRON High...journal article 2012

Yates, S.J.C. (author), Baselmans, J.J.A. (author), Endo, A. (author), Janssen, R.M.J. (author), Ferrari, L. (author), Diener, P. (author), Baryshev, A.M. (author)Microwave kinetic inductance detectors (MKIDs) have shown great potential for sub-mm instrumentation because of the high scalability of the technology. Here, we demonstrate for the first time in the sub-mm band (0.1–2 mm) a photon noise limited performance of a small antenna coupled MKID detector array and we describe the relation between photon...journal article 2011
