Abstract
The present invention discloses an OIC fabrication system which includes a tapered angle computing means for computing a tapered angle for aching a required coupling efficiency. The fabrication system also includes a fabrication control means which includes a tabulated fabricating parameter database for determining and controlling a plurality of fabricating parameters. The fabrication system also includes an etching system which receives a plurality of control signals from the fabrication controlling means to carry out the etching process to form a tapered etching angle such that the optical coupling efficiency can be achieved.
