研究目的
Investigating the scattering of light from ordered and disordered photonic structures to understand the interplay between order and disorder in photonic crystals.
研究成果
The study reveals a nontrivial interplay between order and disorder in photonic structures, where ordered sets of rods can produce disordered patterns and vice versa. This is explained by light scattering only from the intersection points of different rods. The findings provide insights into the general features of light scattering in dielectric photonic structures.
研究不足
The study is limited to thin slabs of woodpile-type photonic crystals and specific types of disorder. The effects of other forms of disorder or thicker samples are not explored.
1：Experimental Design and Method Selection:
The study involves theoretical and experimental analysis of light scattering from woodpile-type photonic crystals with introduced random fluctuations in rod orientation.
2：Sample Selection and Data Sources:
Ordered and disordered woodpile-type photonic structures were synthesized using the direct laser writing technique.
3：List of Experimental Equipment and Materials:
A hybrid organic-inorganic material based on zirconium propoxide with an Irgacure 369 photo-initiator was used, and polymerization was performed with a 50 fs TiF-100F laser.
4：Experimental Procedures and Operational Workflow:
The structures were fabricated layer by layer, with disorder introduced by randomly turning each rod about its center.
5：Data Analysis Methods:
The diffraction patterns were analyzed to study the effects of disorder on light scattering.
