specific Embodiment approach
[0031] A specific implementation of the method for preparing an optical switch based on Mie resonant dielectric particles provided by the present invention includes:
[0032] Choose any crystal of silicon, zinc sulfide, cadmium sulfide or gallium arsenide, add a dispersant, and grind it into powder;
[0033] Put the prepared powder into a constant temperature drying oven for crystallization to obtain the required media particles;
[0034] According to the preset working frequency of the optical switch, the medium particles are dispersed into the transparent solution in a certain proportion to obtain a mixed solution, and the optical switch device is made.
[0035] Here, the preparation method for the medium particles made of zinc sulfide is as follows: the zinc sulfide nanoparticles are prepared by a solid phase method. Weigh pure zinc acetate and finely ground sodium sulfide with a molar ratio of 1:1, put them into an agate mortar and mix them evenly, grind them thoroughly f...

The invention provides Mie resonant medium particles, a preparation method of an optical switch based on the Mie resonant medium particles, and the optical switch, and belongs to the technical field of the optical communication and photoelectron. The medium particles made from silicon, zinc sulfate, cadmium sulfide or gallium arsenide are included, and the optical switch is prepared based on the Mie resonant medium particles. The optical switch based on the Mie resonant medium particles cause the change of dielectric constant of the medium particles by utilizing optical excitation, and then the Mie resonant frequency changes, namely, the optical transmission rate changes to cause the electromagnetic wave transmission characteristic at the detection frequency to change, the on-to-off or off-to-on optical switch characteristics are realized, the optical / optical conversion is realized, the electric signal treating process is eliminated, and the full-optical network in true sense is realized.
Description
technical field [0001] The invention belongs to the technical fields of optical communication and optoelectronics, and more specifically relates to a Mie resonant medium particle, a preparation method of an optical switch based on the Mie resonant medium particle, and the optical switch. Background technique [0002] With the development of information technology, optical communication technology has received extensive attention and application. At present, the development of optical communication technology mainly focuses on two aspects of speed and capacity, among which the transmission capacity of a single optical fiber has been developed rapidly. The bottleneck of optical communication is "electronic bottleneck", that is, the speed and bandwidth of electronic devices cannot meet the needs of today's communication systems. This is caused by factors such as the mobility and relaxation time of electrons themselves, and cannot be eliminated. Contents of the invention [0...
