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.

A distributed feedback laser diode comprising a waveguide with a gain medium assisted by a grating formed by a distribution of elements including a subset comprising localised resonators distributed along an axis of the waveguide, wherein:
- a characteristic frequency of feedback induced on a wave of the guide by the spatial distribution of the elements differs by less than 50% from a resonance frequency of the localised resonators;
- and
- the laser diode is configured such that an optical confinement factor of the wave of the guide with localised resonators is adjusted so as to enable an induced transparency phenomenon.
