A preparation device and method for a highly symmetrical micro-nano optical fiber in the tapered region

Abstract

The invention discloses a preparation device and method of a micro-nano optical fiber with a highly symmetric conical region. The device mainly consists of two pairs of electrically controlled translation platforms which are arranged in a central symmetry manner, a pair of heating devices arranged in a central symmetry manner and a pair of optical fiber clamps, wherein each symcenter is a geometric center of an optical fiber to be drawn. The heating devices adopt oxyhydrogen flames as heat sources, and the electrically controlled translation platforms control the two oxyhydrogen flame heat sources to do reverse reciprocating motion to enable heating regions to be completely symmetric; meanwhile, one pair of electrically controlled translation platforms on which the optical fiber is fixed moves towards a direction where the optical fiber extends, thus realizing preparation of the micro-nano optical fiber with the highly symmetric conical region. By control over parameters such as the displacements, the speeds and the accelerations of the electrically controlled translation platforms, the micro-nano optical fiber with the highly symmetric conical region and different appearance can be obtained.
