Polymer photonic crystal hollow-core fibers are drawn by forcing a viscous polymer solution of polysilane through a spinneret orifice. The pattern of the orifice has a large centered hole, which corresponds to the hollow-core, and many small holes, which form a two-dimensional photonic crystal lattice. Each of the holes is connected to pressurized N2 gas. The pressures are regulated to different pressures to obtain the desired photonic crystal hole pattern. The drawn polymer fiber passes through hot zones for a pre-bake process and a post-bake process. Through these processes, the polymer becomes a silica-like photonic crystal hollow-core fiber.
