ABSTRACT:
The optical mirror incorporates a lightguide (20) produced on a surface (23) of a substrate (22) and used for the propagation of a light beam (36) in a direction parallel to said surface, a cavity (30) made in the lightguide (20) and having in the propagation direction a first (32) and a second (34) walls oriented perpendicular to said direction and having in section approximately the shape of a circular arc, the distance (L) separating the two walls being equal to the radius of curvature (R) of the second wall at the optical axis (37) of the mirror and a reflecting material layer (38) deposited solely on the second wall in order to reflect the light beam towards the first wall, the second wall forming a concave reflecting surface.
