Abstract: An optical fiber sensing device and fabrication method therefor, wherein a plurality of individual glass fibers included therein is automatically electrostatically aligned. In the preferred embodiment, a rigid, metal-clad insulative substrate is photolithographically patterned and etched to prepare precise metal lines and connecting bus for the accurate placement of the optical fibers. A 10 kv potential between the etched lines and the fibers will attract and align the fibers with the metal lines. While the optical fibers are held aligned with the metal lines, they are secured thereto by a fast drying adhesive and then the potential released. One edge of the substrate with the attached fibers is diced. The ends of the fibers formed by the dicing operation are used as light transmitters or receivers, while the opposite ends of these fibers are connected to respective light sources and photosensing circuits.
