CEA-Leti’s offers a versatile SOI photonics platform on 300 mm SOI wafers that leverages world-class pre-industrialization equipment. It includes key integrated components for quantum light generation, manipulation and detection. It also offers enabling technology based on classical PICs for applications based on non-photonic quantum platforms. Device library @ 1550 nm includes a large number of components : • Light generation : sources of photon pairs based on spontaneous four-wave mixing • Light manipulation with passive components : low-loss waveguides, filters, mux/demux • Light manipulation with active components : thermo-optical phase shifters and switches, high-speed modulators based on plasma dispersion, variable attenuators • Light detection : high-speed Ge photodetectors, NbN superconducting single photon detectors • I/O : 1D and 2D grating couplers, spot-size converters
