Abstract
A method of manufacturing a fiber ferrule assembly that includes inserting an exposed end portion of a plurality of optical fibers including a core and a cladding into an array of insertion holes disposed in a glass ferrule plate. The glass ferrule plate includes a glass material that differs from a glass material of both the core and the cladding. The method further includes chemically etching the glass ferrule plate and the exposed end portion of the plurality of optical fibers using a chemical etchant for an etching time period. The glass ferrule plate etches at a first etching rate, the exposed end portion etches at a second etching rate, and the first etching rate is faster than the second etching rate such that, after the etching time period, the exposed end portion of each of the plurality of optical fibers protrude from a second surface of the glass ferrule plate.
