(EN) COLORED PHOTONIC STRUCTURE AND METHOD OF FORMING THE SAME
(FR) STRUCTURE PHOTONIQUE COLORÉE ET SON PROCÉDÉ DE FORMATION
Abstract
(EN)
Various embodiments may provide a method of forming a colored photonic structure. The method may include forming an initial photonic structure. The method may also include heating the initial photonic structure to reduce a lattice constant of the initial photonic structure, thereby forming the colored photonic structure exhibiting one or more colors.
(FR)
Selon la présente invention, divers modes de réalisation peuvent fournir un procédé de formation d'une structure photonique colorée. Le procédé peut comprendre la formation d'une structure photonique initiale. Le procédé peut également comprendre le chauffage de la structure photonique initiale pour réduire une constante de réseau de la structure photonique initiale, permettant ainsi de former la structure photonique colorée présentant une ou plusieurs couleurs.
