Air cavity plastic package for high frequency optical devices

A package assembly for an electro-optical modulator comprising:

• an upper plastic body having an upper cavity formed therein;
• a lower plastic body having a lower cavity formed therein and a plurality of conductors, wherein the upper and lower bodies are configured to mate together such that the cavities form an enclosed air cavity between the bodies;
• a chip disposed in the air cavity such that the chip contacts the plurality of conductors;
• and
• an optical feed through connectable to the chip, the optical feed through comprising a first fiber and a second fiber, wherein the optical feed through is sealed as a seal is created between the upper plastic body and the lower plastic body.

A method of packaging and assembling a high frequency optical device, the method comprising:

• providing a lower plastic housing having a lower cavity formed therein, wherein the lower plastic housing includes a plurality of conductors disposed therein;
• placing a chip in the cavity of the lower plastic housing such that a chip contacts a portion of the plurality of conductors;
• placing a first optical fiber and a second optical fiber in the lower plastic housing and connecting the fibers to the chip to create an optical feed through;
• mating an upper plastic housing with the lower plastic housing such that an air cavity is formed between the housings;
• and
• creating a seal between the upper and lower housings, wherein the optical feed through is sealed as the seal is created between the upper and lower housings.
