Terahertz wave pulse amplitude modulation signal and optical pulse amplitude modulation signal conversion amplifier

Abstract

The invention discloses a terahertz wave pulse amplitude modulation signal and optical pulse amplitude modulation signal conversion amplifier. The terahertz wave pulse amplitude modulation signal and optical pulse amplitude modulation signal conversion amplifier is composed of a rectangular cavity, an absorption cavity, a metal block, a vertical waveguide, a horizontal waveguide, three metal films, a terahertz wave and horizontally-transmitted reference light; the rectangular cavity is located at the input end of the terahertz pulse wave; the incident end of the terahertz pulse wave is located at the upper end of the absorption cavity; the absorption cavity is connected with the vertical waveguide; the metal block is arranged in the vertical waveguide and can move; the vertical waveguide is connected with the horizontal waveguide; and the output power of the reference light is in one-to-one correspondence with power inputted into the terahertz pulse wave. The terahertz wave pulse amplitude modulation signal and optical pulse amplitude modulation signal conversion amplifier can convert terahertz wave pulse amplitude modulation signals into optical pulse amplitude modulation signals, so that the cost of a demodulation device of the terahertz wave pulse amplitude modulation signals can be greatly decreased. The amplifier has a very high application value.

Description

technical field [0001] The invention relates to a nanoscale terahertz wave-light wave conversion and amplification device, in particular to a SPP terahertz wave pulse amplitude modulation signal direct-to-light pulse amplitude modulation conversion amplifier based on a conductor-insulator-conductor (MIM) structure. Background technique [0002] In recent years, people have made great progress in the research of various bands in the electromagnetic spectrum, but only in the terahertz band (0.1THz-10THz), people's research is still lacking. Compared with the current wireless communication, the terahertz band occupies a richer and wider spectrum resource, which makes it have great potential and broad application prospects in the field of broadband wireless communication in the future. AM wave communication is a commonly used communication method. In the terahertz AM communication system, the terahertz AM demodulator is an essential device. [0003] At present, progress has be...

Problems solved by technology

Although these technologies have their own strengths, they are all too large in size, have strict requirements on the working environment, and the obtained signal is very weak, requiring an amplifier with a high magnification, so they are expensive and not convenient for practical application.

This makes the terahertz AM demodulator based on the traditional terahertz wave detector too large in size and high in cost, which is not conducive to practical application
