Abstract
A high resolution, rugged fiber optic coupler for use in optical data transmission systems and method of its manufacture. The fiber optic coupler includes a pair of thin silicon wafers having preferentially etched complementary opposed V-grooves. A very thin layer of a deformable hard glass is used as the lining for the V-grooves and also for covering one of the opposed surfaces of the pair of wafers. An optical fiber is held securely within a pair of opposed complementary V-grooves by the deformable hard glass lining. Preferably, the pair of silicon wafers is joined to each other, with the optical fiber held therebetween in the opposed V-grooves, by electrostatic bonding.
