Abstract:
1. A method of manufacturing an optical device, comprising: providing a structure-forming fiber bonded to at least one other optical component, the structure-forming fiber comprising a preferentially-etchable portion having a first etching rate; and etching the preferentially-etchable portion to at least one radial etching boundary and at least one axial etching boundary to produce an optical structure, wherein the radial and axial etching boundaries comprise a material having a second etching rate, wherein the second etching rate is lower than the first etching rate when exposed to an etching medium wherein the etching of the preferentially-etchable portion is through at least one radial opening, wherein the at least one radial opening extends from an inner cladding in the structure-forming fiber to an outer surface of the fiber.
