  • Publication number: 20190177836
    Abstract: A method for producing a waveguide including a germanium-based core and a cladding is provided, the method including a step of “low temperature” depositing of a shell after forming the core by engraving, such that the deposition temperature is less than 780° C., followed by a step of “high temperature” depositing of a thick encapsulation layer. The shell and the encapsulation layer at least partially form the cladding of the waveguide. Optionally, a step of annealing under hydrogen at a “low temperature”, less than 750° C., precedes the deposition of the shell. These “low temperature” annealing and depositing steps advantageously make it possible to avoid a post-engraving alteration of the free surfaces of the core during the forming of the cladding which is less germanium-rich.

  • Patent number: 10320329
    Abstract: The method includes connecting a MOSFET-type transistor to the photovoltaic installation; applying, to the transistor, a signal of a control voltage (Vgs) that crosses a linear regime range (?lin) of the transistor, between two critical voltages including a saturation voltage (Vgs(sat)) and a threshold voltage (Vgs(th)), and measuring the current and the voltage of the photovoltaic installation while the linear regime range of the transistor is being crossed. The control voltage signal (Vgs) of the transistor is generated from a digital control signal. The transistor initially being in short-circuit (?cc) or open-circuit (?co) regime, a command is issued for a first, rapid variation (BT1) in the control voltage (Vgs) in the direction of the linear regime range of the transistor, then a second, slow variation (BT2) in the control voltage (Vgs) crossing the linear regime range of the transistor, the transition between the first and the second variation being discontinuous.
