Publication number: 20250208305Abstract: A method for determining parameters governing the transport properties of charge carriers in an ionising radiation detector. The method involves irradiating the detector and simulating a propagation of charge carrier clouds towards electrodes of the detector, so as to compare the signal resulting from the simulation and the measured signal. This allows an error to be defined, which error is backpropagated to the site of the interaction in the detector. During the backpropagation, the transport parameters of the charge carriers are updated, so as to minimise the error. The propagation/backpropagation operation is iterative and continues until a stop criterion for stopping the iterations is met.Type: ApplicationFiled: December 19, 2024Publication date: June 26, 2025Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Guillaume MONTEMONT, Alexandre DELCOURT

Publication number: 20250207998Abstract: An on-silicon integrated test structure for characterizing the PDL of a “1 to 2” fiber/silicon optical coupler with a two-dimensional diffraction grating (2DGC), includes the 2DGC to be tested configured as an output coupler, mirrored with another “1 to 2” fiber/silicon optical coupler configured as an input coupler, via planar waveguides coupling their respective guided optical terminals. An adjustable phase shifter is arranged at one of these waveguides. A p- or s-polarized optical signal is input via the input coupler. The adjustable phase shifter is controlled to apply a pure phase shift between 0 and ? to the optical signal propagating in this waveguide. The optical signal input to the 2DGC under test then sweeps through all the mixed polarization states. The variation in optical transmission in the 2DGC under test during this sweep gives the PDL.Type: ApplicationFiled: December 26, 2024Publication date: June 26, 2025Applicant: Commissariat à l'Energie Atomique et aux Energies AlternativesInventors: Daivid FOWLER, Leopold VIROT, Philippe GROSSE
