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...
