Abstract:
A method for making an integrated surface-emitting optoelectronic module that achieves the couplings between an optoelectronic device and an optical fiber by passive alignment, the method comprising the steps of:applying photoresist on a silicon substrate and defining a V-groove area needed for disposing the optical fiber using the photolithography procedure; forming a vertical groove within the defined groove area by dry etching and then removing the photoresist; growing a dielectric layer on the silicon substrate using a furnace; covering the whole area except the vertical groove with photoresist using the photolithography procedure and defining a mirror surface area needed for the optoelectronic device; and etching the vertical groove to form a V-groove by wet etching and etching the mirror surface area to form a mirror surface.
