  • Distributed feedback laser diode
    Patent number: 10658816
    Abstract: The invention relates to a distributed feedback laser diode (10) comprising a waveguide with a gain medium assisted by a network formed by a distribution of elements (22) including a sub-set comprising localised resonators (24) distributed along the axis of the waveguide, characterised in that the frequency characteristic of the feedback induced on the wave of the guide by the spatial distribution of said elements differs by less than 50% of the resonance frequency of said localised resonators.
    Type: Grant
    Filed: July 27, 2017
    Date of Patent: May 19, 2020
    Assignees: UNIVERSITE PARIS SUD, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE
