Abstract
The invention relates to a distributed feedback laser diode () comprising a waveguide with a gain medium assisted by a network formed by a distribution of elements () including a sub-set comprising localised resonators () 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.
