Tunable multi-band terahertz pulse wireless communication transmitting device

Abstract

The invention discloses a tunable multi-band terahertz pulse wireless communication transmitting device, comprising: an optical frequency comb generating module, for generating an optical frequency comb; a programmable optical processor, connected with the optical frequency comb generating module and used for performing frequency filtering on the generated optical frequency comb to generate multiple paths of output, each of which includes a single wavelength optical local oscillator and a multi-wavelength optical carrier signal; a modulator, disposed on each output optical path to modulate thebaseband signal to the multi-wavelength optical carrier signal; and a photodetector, connected to each modulator and used for acting on the signal output by the modulator to generate a multi-band terahertz pulse, wherein the center frequency of the terahertz pulse is decided by a center wavelength difference of the each path of output single-wavelength local oscillator and the multi-wavelength baseband optical carrier, the period of the terahertz pulse is controlled by a baseband modulation implemented by the modulator, and the width and time interval of the terahertz pulse are controlled bythe number and interval of wavelengths of the multi-wavelength baseband optical carrier.

AI Technical Summary

Benefits of technology

In this patented technology, there're two ways for generating multiple types of waves called laser light (L) with very large spectral range that work together like short coherence length sources or other specialized devices such as quantum dots). These techniques allow us to create more precise waveforms than previously possible due to their ability to manipulate them through time delays. Additionally, these technologies have been developed into various applications including communications systems, radar detection, biomedical imagery analysis, etc., making it easier to study complex physical phenomena related to electromagnetic radiation.

Problems solved by technology

This patented technology describes different ways to improve the performance of radio waves used over long distances without being too expensive or bulky due to their large spectral resource requirement. One way involves generating specific types of electrical signals called quantum carriers from an atomic level material like nitrogen gas at room temperature. These materials have unique properties making them ideal candidates for use in various applications where they could be applied quickly and accurately. However, there exist limitations associated with these techniques including poor energy transfer caused by strong electric field lines near surfaces, difficulty controllably adjusted wavelengths, and potential interference between multiple devices connected wirelessly.
