1. An electroluminescent device (1) of the type comprising first (14) and second (5) mirrors substantially parallel and framing converting means (7) of electron-hole pairs into photons, and electron and holes generating means (6,8), characterised in that said converting means (7) and the first (14) and second (5) mirrors are arranged so as to ensure containment between said first (14) and second (5) photon mirrors presenting at least a selected wavelength associated to a guided propagation mode, and means of light extraction (13) communicating with a part at least of the converting means and generating means, included between the first and second mirrors, and arranged in the periphery of the converting and generating means to extract out of these at least a part of photons in the guided mode.
