The emissive optical head according to the invention is of the type comprising a single substrate Sb supporting a laser diode La which is coupled to an initiating optical fibre F. The optical fibre F is arranged in a longitudinal groove 3 which can be produced by a die-type forming operation. According to the invention, in a subsequent step, at least one slot 5 is produced transverse to the steep sides between the seat 40 of the laser diode La and the longitudinal groove 3. In a preferred variant, a second slot is produced at the rear of the laser diode, intended to receive a photodiode detecting the fluctuations. Application especially to fibre-optic transmissions. <IMAGE>
