Abstract
An optical coupler comprises at least one optical fiber (1), one laser (2), one photodiode (3), one focusing lens (30) for focusing on the fiber and one plate (41) which reflects the rays coming from the fiber (1) towards the photodiode (3). In order to prevent a ray sent out by the laser (2) from returning to the photodiode (3) after reflection on the input diopter (4) of the lens (30), the optical axis is broken at the height of this diopter (4) by means of a prism (5). The reflected rays do not return to the plate (41).
