Surface Plasma Technology Application

(Summary description)The surface plasmon wave is a wave that exists near the two interfaces. The refractive index distribution on both sides of the interface has a great influence on the field distribution. This can be used for sensing.

Information

1. The surface plasmon wave is a wave that exists near the two interfaces. The refractive index distribution on both sides of the interface has a great influence on the field distribution. This can be used for sensing. At present, the technology of using Kretschmann structure for biosensing has been greatly developed. This sensing technology has a simple structure and high sensitivity. There is no need for markers in the detection process. The sample binding process can be monitored in real time, and the sensor chip can be reused. Many features such as fast response speed. At present, this technology can be used for the analysis of gases, liquids and organic thin films, and is currently mainly used in the fields of life sciences and chemistry. At present, the main products on the market include Biocore 3000 produced by Biocore AB in Sweden.

2. The surface plasmon wave has the characteristics of local distribution, and its distribution depth can be less than the order of wavelength, breaking the diffraction limit, so that the surface plasmon wave can be applied to the production of sub-wavelength order of optoelectronic devices, and it has the use of optoelectronic integration. Manufacture of devices. For example: sub-wavelength waveguides, sub-wavelength Braque mirrors, sub-wavelength lenses, etc. can be made. Since the limit can be broken, the surface plasmon effect can be used for near-field microscopes, exposures, and so on.

3. The application of surface plasma waves in new energy-related devices such as solar cells and LEDs. At present, the surface plasma effect can be used on the solar cell to improve the photoelectric conversion efficiency of the solar cell, and the surface plasma effect can also be applied on the LED to improve its light extraction efficiency. If commercialized products can be developed, surface plasma waves can also contribute to solving human energy problems.
