1. A bidirectional optoelectronic photocoupler comprising:

  • a encapsulating box;

    a micro lens mounted through the top surfaces of said box;

    a light emitting diode mounted on a mounting surface on the bottom of said box in line with the optical axis of said microlens;

    at least one detecting photodiode mounted on the same mounting surface as said light emitting diode and outside the optical axis of said microlens;

    first planar reflecting means placed within said box along the optical axis of said microlens and inclined with respect to said axis made of a semitransparent mirror;

    second planar reflecting means placed within said box in a parallel plane to said first planar reflecting means; and

    support means for holding said first and second planar reflecting means in said box.
