Abstract

A method of forming an optical component includes forming a first mask on an optical component precursor. The first mask is formed with a plurality of waveguide portions extending from a common portion. Each waveguide portion is positioned so as to protect a waveguide region of the optical component precursor where a waveguide is to be formed. The method also includes forming a second mask between waveguide portions of the first mask. The resistance of the second mask to etching varies along at least one dimension of the second mask.
