Description
Technical Field
The invention relates to an ultra-wideband light generation millimeter wave noise generator, belonging to the fields of cryptography, communication, information security and the like.
Background
Noise is an existence form of a substance itself, and inevitably causes interference to generation and transmission of signals. For any system, noise is an unavoidable problem, and only if the noise problem can be solved, the noise problem can be further solved in the related engineering technical field.
The noise generator is an important instrument for analyzing and calibrating the performance of equipment, in particular to an ultra-wideband millimeter wave noise generator with flat frequency spectrum in the millimeter wave range. The manually controllable millimeter wave noise plays a very important role in the fields of communication, navigation guidance, remote sensing control, aerospace and the like. At present, there are two extreme phenomena in the development of noise generators: firstly, the low-frequency millimeter wave noise generation technology is mature, and the threshold is low; secondly, the ultra-wideband millimeter wave noise generation technology is difficult to realize. Continuous random noise signals with uniform power spectrum and stable and controllable power are output in a very wide frequency range, and the difficulties in various aspects of principles, technologies, processes and the like exist.
At present, the implementation approaches of the noise generator mainly comprise two technologies of digital synthesis technology and physical device noise amplification technology. The digital synthesis technology is to generate a section of pseudo-random number sequence by using DSP or FPGA through linear congruence method, memory shift method and other algorithms, and then to convert the pseudo-random number sequence into noise through time-frequency mapping. Although this technique is easy to implement, it is limited by the clock frequency of the device, and the frequency of noise generated by mathematical synthesis tends to be below GHz. The physical device noise amplification technology is constructed by amplifying and controlling noise in a physical device. The usual noise devices are: resistors, saturated diodes, schottky diodes, field effect transistors, etc. Although millimeter wave noise with larger bandwidth can be generated by the technology, a complex experimental instrument is needed by utilizing a physical device noise amplification technology, and the implementation difficulty is high; meanwhile, as the bandwidth increases, the output power of noise generated by the technology decreases, and the spectral density becomes uneven.

In the ultra-wideband photogenerated millimeter wave noise generator, the nonlinear coefficient of the high nonlinear fiber is 10W -1 km -1 And after the amplified ASE noise passes through the high nonlinear optical fiber, nonlinear effect and dispersion effect are generated, and the output spectrum is widened, so that the output spectrum bandwidth is enhanced, and finally, ultra-wideband millimeter wave noise generation with flat frequency spectrum is realized.

Detailed Description
For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, the ultra-wideband photoproduction millimeter wave noise generator of the present invention comprises a super-radiation light emitting diode 1, an optical fiber isolator 2, an erbium-doped optical fiber amplifier 3, a polarization controller 4, a highly nonlinear optical fiber 5 (HNLF) and a high-speed photodetector 6 which are sequentially connected;
the wide spectrum ASE noise generated by the super-radiation light-emitting diode 1 passes through the optical fiber isolator 2, is amplified to a certain power by the erbium-doped optical fiber amplifier 3, is input into the high-nonlinearity optical fiber 5 with a certain distance by the polarization controller 4 in an adjusting way, and is subjected to photoelectric conversion by the high-speed photoelectric detector 6 to output a result; after the amplified ASE noise enters the high-nonlinearity optical fiber 5, nonlinear effect and dispersion effect occur, and the spectrum of the ASE noise signal is widened, so that the spectrum bandwidth of the original ASE noise is enhanced, the final output shows the spectrum characteristic of millimeter wave noise, the 3-dB bandwidth reaches more than 100 GHz, and the ultra-wideband millimeter wave noise is generated.
In the ultra-wideband photo-generated millimeter wave noise generator, ASE noise light emitted by the ultra-radiation light-emitting diode 1 has a spectral width of 50-100 nm.
In the ultra-wideband light-generating millimeter wave noise generator, an erbium-doped fiber amplifier 3 amplifies ASE noise emitted by a super-radiation light-emitting diode 1 to a certain power and then inputs the ASE noise into a high-nonlinearity fiber 5 to act, and the amplified power realizes the power regulation of finally generating ultra-wideband millimeter wave noise.
In the ultra-wideband photo-generated millimeter wave noise generator, the nonlinear coefficient of the high nonlinear optical fiber 5 is 10W -1 km -1 And after the amplified ASE noise passes through the high nonlinear optical fiber, nonlinear effect and dispersion effect are generated, and the output spectrum is widened, so that the output spectrum bandwidth is enhanced, and finally, ultra-wideband millimeter wave noise generation with flat frequency spectrum is realized.
In specific implementation, the superluminescent diode 1 outputs ASE noise with a center wavelength of 1550 nm and a spectral linewidth of 50 nm, and the ASE noise is input into the erbium-doped optical fiber amplifier 3 after passing through the optical fiber isolator 2. When ASE noise is amplified to 1W and above by the erbium-doped fiber amplifier 3, the polarization state of ASE light is regulated by the polarization controller 4, and then the input length is 2 km, and the nonlinear coefficient is 10W -1 km -1 The zero dispersion wavelength is 1550 nm high nonlinear optical fiber 5. Due to the combined effect of various nonlinear effects and chromatic dispersion of the ASE noise in the high nonlinear optical fiber 5, the spectrum of the ASE noise signal can be further widened to be more than 100 nm, the spectrum bandwidth is greatly enhanced, and the final output can show the spectrum characteristic of millimeter wave noise. Theoretically, the technology can realize the generation of millimeter wave noise with the bandwidth of more than 100 GHz. But only experimental results with a bandwidth of 50 GHz are given due to the detection bandwidth limitation of the high-speed photodetector and the spectrometer, as shown in fig. 2. As can be seen from the results of fig. 2, the spectrum of the millimeter wave noise signal output after passing through the highly nonlinear optical fiber is flat, and the 3-dB bandwidth thereof is 50 GHz.
It should be noted that, increasing the amplification power of the erbium-doped fiber amplifier 3, using the highly nonlinear fiber 5 having a higher nonlinear coefficient, and increasing the length of the highly nonlinear fiber 5 can further increase the bandwidth and the spectral flatness of the finally generated millimeter wave noise. In addition, the power adjustment of the finally output millimeter wave noise can also be realized by adjusting the amplification power of the erbium-doped fiber amplifier 3. Therefore, the millimeter wave noise generated by the ultra-wideband photo-generated millimeter wave noise generator disclosed by the invention has the advantages of large bandwidth (more than 100 GHz), uniform spectrum density and adjustable power.
The ultra-wideband photo-generated millimeter wave noise generator provided by the invention has the advantages and positive effects that:
first: the technical scheme realizes millimeter wave noise generation by utilizing an optical method, breaks through the bottleneck of electronic bandwidth, is easy to generate millimeter wave noise with ultra-bandwidth and has a simple structure;
second,: the power of the output noise of the technical proposal depends on the amplified power of the erbium-doped fiber amplifier, and compared with the prior electronic noise generator, the output power of the technical proposal is easy to adjust and the maximum power which can be output is bigger;
third,: the technical scheme is that millimeter wave noise is generated by utilizing the combined effect of nonlinear effect and chromatic dispersion in the high nonlinear optical fiber, and the generated noise has more uniform frequency spectrum density and larger bandwidth.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present invention and the scope of the claims, which are to be protected by the present invention.
