Optical fiber coupler and method of fabrication

摘要

A method of fabricating a coupler for an optical fiber includes generating a beam of photonic energy and imaging a feature of the first mask onto the beam of photonic energy. The method also includes irradiating a substrate with the shaped beam, thereby ablating material from the substrate to create a feature. During the irradiating step, the shaped beam simultaneously irradiates the entire feature of the substrate.
