Abstract

The invention discloses a method and device for generating a first-order ultra wide band signal with adjustable single-wave-length full gloss. Gaussian optical pulse with the positive polarity is utilized for obtaining Gaussian optical pulse with the positive polarity and the negative polarity on the same wave length through optical logic inverters of double ports, and after delaying and combination, the full gloss first-order ultra wide band signal with the single-wave-length is output. The pulse width and radio frequency spectrum of the generated signal are turnable, and the positive polarity and the negative polarity of pulse can be switched. The device is simple in structure, convenient to operate and low in implementing cost, can achieve the functions of the turnable pulse width, a turnable radio frequency spectrum and the switchable pulse polarity, and achieves better practical value and practical operability.

Description

technical field [0001] The invention relates to the technical field of microwave photons and optical communication, in particular to a single-wavelength all-optical adjustable first-order ultra-broadband signal generation method and device. Background technique [0002] UWB technology in wireless communication is considered to be a very promising emerging technology because of its wide bandwidth, high transmission rate, extremely low transmission power, low power consumption, and good confidentiality. , large-capacity wireless communication systems and broadband sensor networks have very broad application prospects. However, because the radio frequency signal is very lossy when propagating in the air, and it is easily blocked by obstacles, and the transmission power specified by ultra-wideband technology is extremely low, so it is mainly used in short-distance wireless communications such as wireless personal area network and wireless local area network. It is not suitable ...
