Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] The standard optical fiber in the present invention can adopt the standard optical fiber of G.652, G.653, G.655, G.656, OM1, OM2 or OM3 specified by the International Telecommunication Union.

[0023] In this embodiment, the steps for preparing a microstructured optical fiber with a core modified by an inverse opal structure are as follows:

[0024] a) Take a quartz capillary 1-1 with bell mouths at both ends (purchased from Jingliang Glass Tube Processing Factory). Ultrasonic cleaning with absolute ethanol and deionized water for 20 minutes, then blow dry with nitrogen for later use;

[0025] b) Configure SiO 2 Precursor solution, SiO 2 The mass ratio of the precursor solution is - TEOS (98wt%): 0.1M / L HCl: absolute ethanol = 1:1:1.5, stir for one hour and set aside;

[0026] c) Prepare a colloidal microsphere solution with a parti...

Abstract

The invention discloses a microstructure fiber with fiber core modified by inverse opal (3DOM three dimensional ordered macroporous material). The method mainly comprises the following steps: preparing a PS or PMMA colloid microballoon solution, and adding a predecessor solution (TEOS or TiBALDH) into the colloid microballoon solution in a certain proportion; growing a segment of colloid crystal in a capillary with a Sol-gel cooperation self assembly method, forming predecessor gel when colloid crystal gap moisture is reduced, and sintering the capillary at high temperature in a box-type furnace and removing the colloid crystal to form an inverse opal composition; vertically cutting two common standard fibers after part coating is removed, inserting the two fibers into the capillary from two ends of the capillary to the inverse opal composition, fixing the fibers with glue, and fixing and packaging the capillary and fibers with a thermoplastic cannula. The microstructure fiber prepared in the invention can be used as a fiber filter and a biomedical sensing member. By using a common standard fiber in preparation, the microstructure fiber can connects a present fibre-optical communication network to facilitate the realization of all-optical sensing network. The microstructure fiber has the advantages of simple preparation, reliability and strong versatility.

Description

technical field [0001] The invention relates to a microstructure, in particular to a microstructure optical fiber and a preparation method thereof. Background technique [0002] Applying the bandgap structure of photonic crystals to optical fibers forms photonic crystal fibers (Photonic Crystal Fiber, PCF), also known as microstructured optical fibers. Using UV write-out technology or CO 2 Thermal shock technology can write photonic crystal fiber gratings in PCF. Microstructured fiber gratings have rich structural and optical properties. Changing the microhole arrangement, size and duty cycle in the fiber, or loading the medium into the microhole can change the optical properties of the photonic crystal fiber and its grating, and greatly change the performance of the fiber microstructure. However, its production cost is high, and there are many problems in its connection with ordinary optical fibers. [0003] To manufacture photonic crystals in the optical and near-infra...
