Optical radiation modulation method, an electrooptical modulator(variants) and an electrooptical device(variants)

摘要

The invention strength and phase of the optical radiation by using a strain relief phase, and a surface plasmon resonance phenomenon and an optical modulation by controlling the characteristics. ; The present invention is achieved by combining the advantages of the relief phase history and a surface plasmon resonance phenomenon. The proposed technical result is achieved as in the realization of the present invention, because the main optical axis in the transition from the on to the input electrical signal into an opportunity for full deviation (conversion) of radiation, composed of a controlled increase in the efficiency of the optical radiation. Where & lt achieved; & a plate-like effect & & . By, it is possible to increase the sensitivity, the contrast and the resolution of the processed optical information ; First, a prism and a diffraction grating on both sides gets the chance of a dynamic control of the surface plasmon resonance phenomenon. As a highly sensitive sensor to respond in real time to the proposed method, and the modulator is characteristic change of the dielectric medium, and, in particular, may be used in nanotechnology. ; The present invention is adjustable as a diffraction grating, a light machine industry, (biology, chemistry, etc. of) gas, liquid and solid genetic control of sensitivity and resolution sensor medium, projection and display TV, print and communication equipment, optical fiber switching and optical filtering devices, high-speed linear and matrix printers and other technology can be applied to the field. 11 drawings.
