The first fin structure has a first primary surface, a second primary surface opposite the first primary surface, and a plurality of edges between the first and the second primary surfaces including a first edge and a second edge opposite the first edge. The first fin structure is physically coupled to the support plate with the first edge of the first fin structure attached to the first primary surface of the support plate. The second fin structure has a first primary surface, a second primary surface opposite the first primary surface, and a plurality of edges between the first and the second primary surfaces including a first edge and a second edge opposite the first edge. The second fin structure is physically coupled to the support plate with the first edge of the second fin structure attached to the first primary surface of the support plate. The first diode laser is physically coupled between the first and the second fin structures to emit the first laser beam in a direction away from the support plate.
Abstract:
An interface device includes a double-trench structure configured to bond to a flip-chip device electrically and thermally. The double-trench structure is at least partially metalized and configured to allow a soldering material to flow along each of at least two trenches of the double-trench structure. The two trenches are closely located adjacent to each other to minimize an electrical separation gap between a cathode and an anode of the flip-chip device while providing electrical isolation therebetween.
