摘要： A multi-chip package assembly includes a substrate, a first semiconductor chip attached to the substrate, and a second semiconductor chip attached to the substrate, such that a portion of the second semiconductor chip overhangs an edge of the substrate. A first v-groove array for receiving a plurality of optical fibers is present within the portion of the second semiconductor chip that overhangs the edge of the substrate. An optical fiber assembly including the plurality of optical fibers is positioned and secured within the first v-groove array of the second semiconductor chip. The optical fiber assembly includes a second v-groove array configured to align the plurality of optical fibers to the first v-groove array of the second semiconductor chip. An end of each of the plurality of optical fibers is exposed for optical coupling within an optical fiber connector located at a distal end of the optical fiber assembly.

摘要： A handle-integrated composite wafer assembly includes a handle wafer attached to a device wafer. The device wafer includes a device layer formed on a buried oxide layer. The device layer includes an optical resonator structure. The handle wafer includes a base layer and a layer of anti-reflective material disposed on a top side of the base layer. The base layer has a cavity extending into the base layer from the top side of the base layer. The cavity has at least one side surface and a bottom surface. The layer of anti-reflective material is substantially conformally disposed within the cavity on the at least one side surface and bottom surface of the cavity. The handle wafer is attached to the device wafer with the layer of anti-reflective material affixed to the buried oxide layer, and with the cavity substantially aligned with the optical resonator structure in the device layer.
