Problems solved by technology

[0003] At present, the preparation of photonic crystals mostly adopts the method of self-assembly template combined with sol-gel. The above-mentioned method has the following disadvantages: 1. Poor controllability in the process of self-assembly template
2. Many fractures during high temperature sintering
However, the preparation of photonic crystals by the template method still cannot fully meet the requirements of high controllability, less fracture, high degree of order, and good crystallinity of photonic crystal samples.

Abstract

The invention discloses a preparing method for an aluminum oxide two-dimensional photonic crystal. The preparing method includes the following steps that an aluminum sheet is pretreated and subjected to anode electrochemical polishing; first-time anodizing is conducted; a first-time oxide film is removed; and second-time anodizing and chambering treatment are conducted. The requirements for high controllability, small fractures, a high degree of order and good crystallinity of a photonic crystal sample in the preparing process of the two-dimensional photonic crystal are met.

Description

technical field [0001] The invention belongs to the technical field of photonic crystals, and in particular relates to a method for preparing aluminum oxide two-dimensional photonic crystals. Background technique [0002] In recent years, photonic crystals have shown great application prospects in zero-threshold lasers, quantum computers, optical waveguides, and optical switches. According to the geometric characteristics of photonic crystals for light modulation, they can be divided into: one-dimensional photonic crystals, two-dimensional photonic crystals, and three-dimensional photonic crystals. Since the refractive index satisfies the periodic arrangement in two dimensions, and the other dimension is evenly distributed, two-dimensional photonic crystals have more arrangements, so two-dimensional photonic crystals are widely used in optical waveguides, photonic crystal fibers, and fluorescence enhancement. As a dielectric material, alumina has low plasma absorption and h...
