Abstract
A method for forming lenses for a fiber optic connector includes forming a mask on a photosensitive glass, the mask defining a plurality of covered portions of the photosensitive glass and a plurality of open portions of the photosensitive glass that are positioned between the plurality of covered portions, exposing the photosensitive glass and the mask to electromagnetic energy, removing the mask from the photosensitive glass, forming wafer-level lenses at the plurality of covered portions of the photosensitive glass by exposing the photosensitive glass to thermal energy, and applying an anti-reflective coating to an upper surface of the photosensitive glass.
