An air cavity package includes a dielectric frame that is formed from an alumina ceramic, a polyimide, or a semi-crystalline thermoplastic. The dielectric frame is joined to a flange using a high temperature silicone adhesive. Leads may be bonded to the dielectric frame using a high temperature organic adhesive, a direct bond, or by brazing.

A cap assembly for optical communications comprising a housing that includes a front side perpendicular from a bottom side, opposing parallel first and second sides perpendicular from the bottom side, and a back side disposed perpendicularly between the first side and the second side offset from respective ends of the first side and the second side opposite the front side. The back side includes an opening there-through and a three-sided ledge formed along an interior of the first side leg, an exterior of the back side, and an interior of the second side leg. The cap assembly further includes a window configured to contact the three-sided ledge of the back side, the glass panel covering the opening there-through and attached to the assembly via a solder pre-form.

An air cavity package includes a flange and a pedestal extending upward from the flange. A dielectric frame is joined to the flange and surrounds the pedestal. The semiconductor die is placed on the pedestal, which reduces the length of the wires joining the die to the leads of the air cavity package.
