The invention discloses a resonant mode manipulation method and manipulation system, electronic equipment and storage medium, which relate to the technical field of photonic crystals and are used to make the resonant mode in the case of ensuring that a one-dimensional photonic crystal nano-beam cavity has a target resonant mode. The manipulation is more flexible, and the difficulty of applying one-dimensional photonic crystal nanobeam cavity to multi-parameter sensing and detection is reduced. The method includes: determining mode shift information according to the current resonance mode and the target resonance mode of the one-dimensional photonic crystal nanobeam cavity. According to the current resonance mode, mode shift information and current structure information of the one-dimensional photonic crystal nanobeam cavity, the target structure information of the optical field local area of the one-dimensional photonic crystal nanobeam cavity is determined. The target structure information includes at least the structure information of the periodic pores. According to the target structure information of the local area of the optical field, the local area of the optical field is adjusted to adjust the current resonance mode of the one-dimensional photonic crystal nanobeam cavity to the target resonance mode.
Description
technical field [0001] The present invention relates to the technical field of photonic crystals, and in particular, to a manipulation method and manipulation system of a resonance mode, an electronic device and a storage medium. Background technique [0002] Introducing point defects on perfect photonic crystals or photonic crystal waveguide structures. According to the energy band theory calculation of photonic crystals, the frequency points of one or more defect states will be introduced into the photonic band gap, and the optical field of a specific frequency point will be localized. Domains surround this point defect, thus forming the basic model of the photonic crystal microcavity structure. Among them, the one-dimensional photonic crystal nanobeam cavity is formed by introducing defects into the one-dimensional photonic crystal waveguide. In practical applications, a programmed high-Q one-dimensional photonic crystal nanobeam cavity design method is usually used to d...
