Abstract

The invention relates to a device for drawing the fiber v rod of polymer photon crystal into polymer photon crystal fiber, which comprises a system control device, a diameter-measure device, a prefabricated-rod clamp is fixed on the upright post, a heating furnace under the prefabricated-rod clamp, a wire-drawing device under the heating furnace, a guide wheel under the wire-drawing device, and a wire-coiling device at the back of guide wheel. Wherein, the clamp head of prefabricated-rod clamp is connected with a sliding block; the sliding block is connected a lead-screw thread; and the lead-screw thread is connected to motor and vertical arranged on the upright post. The invention can solve the problems of present technique which needs high heating temperature, bigger device volume, high cost, and lower productivity. Said invention has the advantages of tight structure, easy process control, high property and high quality while the temperature of heating furnace is around 200Deg. C.

Description

technical field [0001] The invention belongs to the field of optical fiber manufacturing equipment, in particular to a drawing equipment for polymer photonic crystal optical fiber prefabricated rods, which can be used for drawing polymer photonic crystal optical fibers. Background technique [0002] Photonic crystal fiber is a next-generation transmission fiber with special structure developed based on photonic crystal technology. Macroscopically, photonic crystal fiber is very similar to traditional ordinary single-mode fiber; but microscopically, the structure of the two is completely different. The cross-section of photonic crystal fiber is composed of a very small hole array, similar to the crystal lattice in the crystal, Therefore, photonic crystal fibers are also called holey fibers or microstructured fibers. The light guiding principle of traditional optical fiber is total reflection; the light guiding principle of photonic crystal fiber is to work in a single mode i...
