Abstract
A method and apparatus for polishing the side surfaces of fiber optics destined for devices in which the evanescent optical field of the optics must be accessed through polished side surfaces thereof. A plurality of fiber optics are temporarily affixed to a rounded surface, for polishing of the outer-facing surfaces thereof. In one embodiment, fiber optics are positioned across a cylindrical lens, perpendicular to a longitudinal axis thereof, and are temporarily affixed thereto using a wax. Polishing commences, which can be monitored for progress using visual or optical power measurements. The fiber optics are thereafter removed from the lens, ready for installation into their respective devices.
