Abstract: An optical input/output chiplet is disposed on a first package substrate. The optical input/output chiplet includes one or more supply optical ports for receiving continuous wave light. The optical input/output chiplet includes one or more transmit optical ports through which modulated light is transmitted. The optical input/output chiplet includes one or more receive optical ports through which modulated light is received by the optical input/output chiplet. An optical power supply module is disposed on a second package substrate. The second package substrate is separate from the first package substrate. The optical power supply module includes one or more output optical ports through which continuous wave laser light is transmitted. A set of optical fibers optically connect the one or more output optical ports of the optical power supply module to the one or more supply optical ports of the optical input/output chiplet.

Abstract: An optical modulator is disclosed that includes an optical resonator structure. The optical resonator structure includes at least one non-linear portion, the at least one non-linear portion comprising at least one radial junction region. The at least one radial junction region is formed between at least first and second materials, respectively, having different electronic conductivity characteristics. A principal axis of the at least one radial junction region is oriented along a radius of curvature of the at least one non-linear portion. The optical modulator includes an optical waveguide that is coupled to the at least one non-linear portion of the optical resonator structure.

Abstract: A method for managing embedded software modules for an electronic computer embedded in an electrical switching device for switching an electric current includes acquiring a software module including a runnable code and a service contract declaring the hardware resources required by the runnable code when it is run by the computer; installing the software module inside a host receptacle intended to form an environment for running a software module and including a memory location defined statically inside a memory of the computer and being associated with a subset of hardware resources of the computer; running the software module including a step consisting in verifying whether the operation of running of the software module respects the service contract, the running operation being allowed to continue if the service contract is respected and, otherwise, a recovery step is implemented in order to interrupt the running operation.
