Abstract
An optical package for use with a laser diode in high speed applications. The package comprises a metallic housing with a multilayer ceramic (MLC) insert disposed through a sidewall thereof. The MLC insert is utilized to form a microstrip transmission line of a bandwidth sufficient to couple a high frequency signal source to the laser. A number of conductive vias are disposed through the thickness of the MLC insert at the package wall to serve as electric field shorts within the insert and improve the frequency response of the microstrip. A pair of such MLC inserts may be disposed through opposing sidewalls of the package and used to provide a conventional 'butterfly' configuration, while preserving the integrity of the microstrip interconnection.
