Fabrication of Precision Conical Profiles on Optical Fibers by Nano-Grinding
A sophisticated control architecture that can he used to precisely center optical fibres with respect to a high precision axis of rotation is presented. Precision centering is extremely important in making integrated micro-lenses that are expected to have high efficiency in collimation and light coupling. A microscopic lens system and sub-pixel edge detection methods have been used to achieve a centering precision less than 0.5 祄. A nano-grinding machine incorporating these features have been developed to grind conical micro-lenses. High quality surface finishes are made possible by ensuring that grinding takes place in the ductile regime. This paper describes the fiber grinding machine and its associated control systems, including vision processing in detail. Experimental results of centering precision and machined lenses are presented.
