Maskless micromachining of all-fiber photonics structures, based on the selective etching of structure forming optical fibers (SFF) is presented. A maskless micromachining process can reform or reshape a section of an optical fiber into a complex 3D photonic microstructure. This proposed micromachining process is based on the introduction of phosphorus pentoxide (P2O5) into silica glass through standard fiber manufacturing technology. Micro-machining is presented as a highly effective tool for the realization of new solutions in the design of optical sensors and microfluidic devices.
