Abstract
The invention relates to a coupler for connecting optical fibers and electro-optical elements by means of a flexible polyimide substrate which is provided with a hole for positioning the fiber. The substrate is also provided with small metallized holes, covered with a metal bump, for connection of the electro-optical element.
Claims4
A coupling device, for coupling an optical fiber to an electro-optical element, comprising:
- a substantially flat connection element having a hole therethrough for accomodating an end of the optical fiber to be inserted in the hole via an opening on a first side of the connection element, said connection element having an electrically conductive pattern on a second side, opposite to the first side, for conducting electrical power to the electro-optical element;
- means for securing the optical fiber in the hole of the connection element;
- and
- means for securing the electro-optical element to the electrically conductive pattern on the second side of the connection element;
- characterized in that the substrate has at least one additional hole, the inner wall of which is metallized, said hole having an opening at the second side being covered with a metal bump, said electrically conductive pattern comprising the metal bump, and said means for securing the electro-optical element also comprising said metal bump.
