In one embodiment, an apparatus includes a microelectronic package comprising a plurality of semiconductor chips connected to a substrate and a stiffener mounted on the substrate. The stiffener is mounted on the substrate with the semiconductor chips disposed within an opening in the stiffener and the opening defines an asymmetric shape relative to the semiconductor chips to control overall warpage in the microelectronic package by the stiffener.

Stiffener for providing uniformity in microelectronic packages

Systems, devices, methods, and computer-readable media for preventing laser kink failures. A laser diode device can include one or more laser diodes configured to emit electromagnetic radiation coherently. The laser diode device can also include one or more submounts upon which the one or more laser diodes are mounted. The one or more submounts can include one or more through vias including one or more fill materials different from a material of the one or more submounts. Further, one or more properties of the one or more through vias in the one or more submounts can be selected to reduce an amount of mismatch between an effective coefficient of thermal expansion of the one or more laser diodes and an effective coefficient of thermal expansion of the one or more submounts.
