Bidirectional optoelectronic component operating as an optical coupling device
First Claim
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.

Abstract
The invention concerns bidirectional optical fiber connections, and more particularly an optical coupling device between an emitting electroluminescent diode and a detecting photodiode, the optoelectronic component according to the invention comprising an electroluminescent diode called DEL sealed in a box of the transistor box type the cover of which carries a microlens centered on the optical axis of the box, while inside the box are integrated: a photodiode mounted at the side of the DEL and outside the optical axis, a semitransparent mirror and a mirror support, this support being machined so as to form a second mirror that reflects light to be detected towards the detecting diode; the novel component can be used in bidirectional optical connections, in computers and telephone exchange centers.
