    Abstract: A device package and a method of forming a device package are described. The device package includes a lid with one or more legs on an outer periphery of the lid, a top surface, and a bottom surface, where the lid is disposed on the substrate. The legs of the lid are attached to the substrate with a sealant. The device package also has one or more dies disposed on the substrate. The die(s) are below the bottom surface of the lid, where each of the dies has a top surface and a bottom surface. The device package further includes a retaining structure disposed between the bottom surface of the lid and the top surface of the die, where the retaining structure has one or more inner walls. The device package includes a thermal interface material disposed within the inner walls of the retaining structure and above the top surface of the die.

    Abstract: Embodiments of the invention include an optical routing device that includes an organic substrate. According to an embodiment, an array of cavities are formed into the organic substrate and an array of piezoelectrically actuated mirrors may be anchored to the organic substrate with each piezoelectrically actuated mirror extending over a cavity. In order to properly rout incoming optical signals, the optical routing device may also include a routing die mounted on the organic substrate. The routing die may be electrically coupled to each of the piezoelectrically actuated mirrors and is able to generated a voltage across the first and second electrodes of each piezoelectrically actuated mirror. Additionally, a photodetector may be electrically coupled to the routing die. According to an embodiment, an array of fiber optic cables may be optically coupled with one of the piezoelectrically actuated mirrors and optically coupled with the photodetector.
