Fabrication of Microstructured Optical Fiber (MOF) segments by two-photon lithography 3D printing

Microstructured optical fibers (MOFs) have interesting properties such as high birefringence, high nonlinearity, and endlessly single-mode operation [1] . MOFs are optical fibers made with a single material, in which an array of micron-sized longitudinal holes enables light guidance. The design of the hole pattern allows controlling the optical properties of the MOFs.
