ABSTRACT:
A lens is produced on the end of a single mode optical fiber by first coupling light into the fiber so that the light projects out the end of the fiber on which the lens is to be produced. The fiber end is then dipped in and out of a drop of negative photoresist and held in a vertical position while the photoresist wicks up the fiber and dries. The dipping and drying is continued until a sufficient lens of photoresist is built up which lens tends to build in the desired shape due to the Gaussian distribution of the light projecting out the end of the fiber and the flow of photoresist up the fiber.
