Abstract
A 3D micro optical switching system (3D-MOSS) is fabricated by dividing an optical switching system into several blocks, creating optoelectronic layers where optical switches or tunable filters in each block are disposed, laminating the optoelectronic layers by connecting the layers with optical connections. The fabrication process includes a first step of selectively exposing an adhesive bond whose adhesive strength changes by exposure, a second step of contacting the selectively-exposed adhesive bond with a thin-film device array on a first substrate, and a third step of selectively ring part of thin-film devices in the thin-film device array from the first substrate onto the selectively-exposed adhesive bond in accordance with an exposure pattern.
