Meanwhile, the manufacturing difficulty of the photonic crystal can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of photonic crystals, in particular to a multi-layer polymer film three-dimensional photonic crystal and a manufacturing method thereof. Background technique [0002] In the highly informatized era, the amount of information is huge, which puts forward higher requirements on the speed and capacity of information transmission and processing. As an information carrier, photons have many advantages over electrons. Optical information transmission has a large bandwidth and high speed, and the optical signal processing speed is fast, and it is not disturbed by electromagnetic fields. These advantages make photons play an important role in the information society. Like semiconductor crystals that can manipulate electrons, photonic crystals are artificial periodic dielectric materials that can control the behavior of photons. They can form periodic distributions of refractive index in one-dimensional, two-dimensio...
