Advance on Ocean Optical Sensor in view of Micro nano Materials Technology

Abstract The purpose of this paper is to demonstrate the feasibility of a new technical route based on the characteristic absorption spectra of Marine water bodies based on the current typical semiconductor materials. According to the design and calculation results, it can be concluded that with silicon oxide, silicon nitride, titanium dioxide and gallium phosphide as typical application materials, the multi-medium spacer layer structure is adopted, and the dielectric metassurface-multi-channel narrowband filter constructed in the band of 473~493nm and 635~655nm is divided into four channels. This design fully exploits the advantages of simple, tunable metasurface fabrication, and can adjust the filter’s transmission wavelength by altering its transverse geometric parameters for admittance matching. In general, it is feasible to construct a medium metasurface multi-channel narrow band filter using a multi-medium spacer layer structure, and integrate a variety of transmission-wavelength narrowband filters on the same substrate through a planar graphic process such as lithography, to form an antenna design based on micro and nano arrays.
