Embodiment Construction
[0027] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0028] In the prior art, the rise and fall times of microwave pulses can only be compressed to the order of ns. In order to further obtain ultra-fast microwave pulses with narrower edges, the present invention proposes an ultra-fast microwave pulse generator, such as figure 1 As shown, the device includes a frequency synthesizer 1 , a dissipative soliton resonance mode-locked fiber laser 2 , an electro-optic modulator 3 , and a photodetector 4 . The frequency synthesizer 1 generates a slow-edge microwave pulse with a large...

The invention discloses an ultra-fast edge microwave pulse generation device and method. The device comprises a frequency synthesizer, a dissipative soliton resonance mode-locked fiber laser, an electro-optical modulator and a photoelectric detector, the frequency synthesizer comprises a first output end and a second output end, and the first output end outputs a microwave pulse signal as a pulse to be shaped and is connected with a radio frequency input end of the electro-optical modulator; the second output end outputs a synchronous clock signal to be connected with the input end of the dissipative soliton resonance mode-locked fiber laser for realizing clock synchronization; the output end of the dissipative soliton resonance mode-locked fiber laser outputs a rectangular optical pulse as an optical carrier and then is connected with the optical input end of the electro-optical modulator, the electro-optical modulator modulates a microwave pulse signal to be shaped onto the rectangular optical pulse carrier, the output end outputs a modulated rectangular optical pulse, and then the rectangular microwave pulse is converted into a rectangular microwave pulse through a photoelectric detector.
Description
technical field [0001] The invention relates to the field of optoelectronic technology. More specifically, it relates to a device and method for generating ultrafast edge microwave pulses. Background technique [0002] High-speed pulse technology is a technology for researching high-speed pulse generation, transmission and measurement. As the basis of modern electronic technology, it has a wide range of applications. Among them, the pulse edge is becoming more and more steep, and the ultra-fast edge pulse with ultra-fast rise time and fall time is an important development direction. [0003] Ultra-fast edge pulses are widely used in many fields such as wireless communication, high-speed signal sampling, and radar systems. With the gradual deepening of research, the requirements for key indicators are getting higher and higher, and the edge time is developing from ns to ps. Pulse edge compression using traditional electrical methods such as step recovery diodes, tunnel diod...
