Opto-electronic coupling head and method for fitting such a head

摘要

An opto-electronic coupling head which can either be an emission head coupling a light emitting diode to an optical fiber, or a reception head coupling an optical fiber to a photodiode. The head has a diode mounted on the base of a case for a semiconductor device and uses the cap of said case which has previously been stamped and perforated at the top. A fiber holder has a shoulder which abuts against the edges of the opening made in the cap and in conjunction with the electric welding of the cap to the base helps to fix the fiber holder in the case. The optical fiber is previously fixed by a deposit of solder in the axial opening of the fiber holder.
