A process of fabricating a non-gap 3-D microstructure array mold core comprises a first step in which a buffer layer is coated on a substrate. A photomask layer is then coated of the buffer layer. A pattern is subsequently formed on the photomask by photo-lithography. The patterned photomask layer is subjected to a reflow by which a microstructure array is formed on the photomask layer. The microstructure array is coated with a metal conductive layer. The microgaps of the microstructure array are eliminated by an electrocasting layer which is coated on the microstructure array. The non-gap microstructure array mold core so fabricated is made into a metal molding tool by microinjection molding or microthermo-pressure molding.

The present invention provides a fabrication process for making an integrated micro spherical lens for an optical switch. Through a semiconductor micro imaging process and a wet-etching process of micro electromechanical working, a plurality of V-shape grooves and mesas are formed on the surface of a base. A further micro imaging process, an etching process and a heat tempering process are used to form a micro spherical lens on the mesa, so that an integrated micro spherical lens and fiber array can be precisely arranged.

A method of making a micro magneto-controlled optical path-guiding platform comprises an optical path-guiding platform, couples of the optical routes, a micro magneto-flux prism located at the intersection of the optical route on the topside of the platform, and a magnetic field generator oppositely mounted under the location of the micro magneto-flux prism of the platform bottom side respectively. Therefore, the reflection ratio and refraction ratio to the incident optical signal traveling through this designed micro magneto-flux prism will be completely manipulated by adjusting the magnetic field intensity that is generated by the magnetic generator. Conclusively, this invention can be used to change the traveling orientation of the optical route or control the optical energy intensity as desired.
