Description
Technical field
The present invention relates to a kind of drawing and the integrated polarization silica fibre producing device of polarization.
Background technology
Along with two-forty, large bandwidth, the arrival in the full opticfiber communication of low-loss epoch, the phase modulator of all optical fibre structure becomes current urgent need.Yet the material that forms optical fiber is fused silica, because having macroscopical center inversion symmetry, does not have second order nonlinear effect.Experiment shows, to the thermal poling processing of optical fiber, can make it produce permanent second order nonlinear effect.At present mostly the treatment process of thermal poling is to utilize the electropolarization that adds after electrode insertion in diplopore optical fiber or rubbing down optical fiber the method for micro-strip electrode to realize optical fiber, and still, these methods are made difficulty, cost is high.(reference: (1) T. Fujiwara, D. Wong, and S. Fleming. " Large Electrooptic Modulation in a Thermally-poled Germanosilicate Fiber; " Photonics Technology Letters, Vol.7, pp. 1177-1179:1995.

In order to reduce the cost of manufacture of polarized optical fibre, the making of polarized optical fibre is become easily, simple, meanwhile, increase the length of polarized optical fibre, how people begin one's study in pulling process to the method for electrode insertion in optical fiber.The people such as Kenneth Lee have punched by ultrasonic grinding in prefabricated rods, to electrode insertion in hole, are then drawn into together electroded optical fiber, then polarize, and have obtained the long polarized optical fibre of 200m.This greatly reduces to the difficulty of electrode insertion in diplopore optical fiber.(reference: (3) Kenneth Lee, Peifang Hu and Justin L. Blows, " 200-m optical fiber with an integrated electrode and its poling ", Optical Letters Vol. 29, pp, 2124-2126:2004. (4) Kenneth Lee, Peter Henry, Simon Fleming, and Justin L. Blows, " Drawing of Optical Fiber With Internal Codrawn Wire and Conductive Coating and Electrooptic Modulation Demonstration ", Photonics Technology Letters, Vol. 18, pp, 914-916.).
Although solved metal electrode to the problem of electrode insertion in diplopore optical fiber, the method to electrode insertion in optical fiber in pulling process cannot solve the polarized optical fibre that draws random length.Therefore the polarized optical fibre that, how to draw out random length will be a very important research topic.
Summary of the invention
Weak point for above-mentioned technology, the object of the present invention is to provide a kind of drawing and the integrated polarization silica fibre producing device of polarization, remaining temperature when this device utilizes optical fiber to walk out graphite furnace is as the thermal source of thermal poling, in pyrographite stove lower port, place arranges high voltage polarization electrode, realizes wire drawing integrated with polarization.

Described high voltage polarization electrode is connected with high-voltage power supply by high-voltage conducting wires, and described high voltage polarization electrode is fixed in polarizing electrode regulation system, and described polarizing electrode regulation system is placed on mobile platform.
Described high voltage polarization electrode is vertically placed, and insulation layer, through polishing, is placed with fixed electorde between two electrodes in the edge of electrode; Two interelectrode distances are 0.7-1 mm, and corresponding polarizing voltage is 1200-1400 V.
According to the drawing method of ordinary optic fibre, first draw silk, the high-voltage power supply when drawing thread on high voltage polarization electrode should be in off-state to guarantee safety.Draw after an end of processing, start that polarizing electrode is applied to high-voltage optical fiber is polarized.Optical fiber does not have polarized in the last period.From the fiber segment of polarization, start to draw as required the polarized optical fibre of different lengths, and realized the integrated of fibre-optical drawing and polarization.
The present invention compared with prior art, has following apparent outstanding substantive distinguishing features and remarkable advantage:
The present invention is the drawing of the polarized optical fibre based on small-sized, special fiber-pulling machine, owing to not needing to make diplopore optical fiber and grow again thin electrode, does not need electrode to stretch into inside of optical fibre, can reduce technical difficulty and reduce expenses.In addition, this device is that the mode of directly adding polarizing electrode on fiber-pulling machine is carried out, and these advantages make the making of polarized optical fibre easier, with low cost.Meanwhile, the outside that electrode is placed in to optical fiber has also solved the technical barrier that the single hole polarized optical fibre of electrode in band is difficult to random length and draws; Eliminated because of polarizing electrode impact on polarized optical fibre characteristic in optical fiber.
