The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] Frequency converters play the role of frequency conversion in the transmitting and receiving modules of communication systems. They have been widely used in wireless communication, radar, satellite communication and other fields. Traditional microwave frequency converters process signals in the electrical domain, which will inevitably be affected by electronic bottlenecks and cannot meet the requirements of modern communication systems. Specifically, the processing speed and accuracy of signals in the electrical domain will be affected due to the limitations of frequency band and sampling frequency, which makes it difficult for traditional microwave frequency converters to meet the requirements of modern communication systems for high-speed, broadband and efficient signal processing. Microwave photonic technology fully combines the advantages of microwave and photonics technology, and has the characteristics of large bandwidth, low loss and anti-electromagnetic interference. These characteristics enable microwave photonic frequency converters to effectively overcome the problems of traditional microwave frequency converters. Specifically, microwave photonic frequency converters use photons as information carriers, and their bandwidth far exceeds that of electronic devices. For example, microwave photonic frequency converters can make the bandwidth of optical communication reach tens of GHz or even THz levels, while the bandwidth of traditional microwave frequency converters is generally only a few GHz, which enables microwave photonic frequency converters to process wider bandwidth signals and meet the needs of modern communication systems for high-speed data transmission. Microwave photon converters can make the loss of optical communication in long-distance transmission much lower than that of traditional copper wires. Therefore, microwave photon converters can maintain low loss and improve transmission efficiency when realizing long-distance signal transmission. In addition, microwave photon converters can make optical communication have the advantage of anti-electromagnetic interference. Therefore, microwave photon converters can still maintain stable performance in the load electromagnetic environment and improve the reliability of the communication system.

[0034] Furthermore, modern communication systems also involve frequency hopping functions. In optical communications, frequency hopping functions achieve anti-interference and confidentiality of communication by rapidly changing the frequency of optical signals. For example, nonlinear optical effects or optoelectronic devices can be used to achieve frequency conversion of optical signals. At the hardware level of the system, frequency hopping and frequency conversion functions are usually dispersed in multiple independent modules. This decentralized design increases the number of hardware connections and interfaces, thereby increasing the complexity and cost of the system. For example, it increases the difficulty of rapid signal switching, reduces the efficiency of signal processing, and may also lead to increased system power consumption and weakened anti-electromagnetic interference capabilities.

[0035] Therefore, how to realize the integration of frequency hopping function and frequency conversion function in optical communication, that is, how to integrate frequency hopping function and frequency conversion function in the same module or component instead of dispersing them in multiple independent modules, while maintaining the advantages of microwave photonic technology such as large bandwidth, low loss, and anti-electromagnetic interference, improve the integration level of optical communication components, thereby realizing fast switching and efficient processing of optical signals, is the focus of microwave photonic frequency converter research.

[0036] The microwave photon frequency hopping conversion device and method according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of a microwave photon frequency hopping device provided in an embodiment of the present application. Figure 1 As shown, the microwave photon frequency hopping device includes a first optical carrier module, a second optical carrier module, at least one optical signal processing module, an optical signal merging module, an optoelectronic conversion module and a control module, wherein:

[0038] The first optical carrier module can generate a first optical carrier signal containing different wavelengths, and the first optical carrier signal can present a series of frequency components with uniform intervals and coherent stable phase relationships on the spectrum. The optical signal processing module is connected to the first optical carrier module, and screens, loads the signal to be converted and performs signal compensation operations on each first optical carrier signal, thereby generating a second optical carrier signal, and filtering the sideband and stray signal operations on the second optical carrier signal. The second optical carrier module generates a third optical carrier signal loaded with a local oscillator radio frequency signal for mixing and demodulation. The optical signal merging module is connected to the second optical carrier module and each optical signal processing module, and combines the third optical carrier signal with each second optical carrier signal. Through wavelength division multiplexing operations, the transmission of multiple optical signals can be realized, thereby improving the transmission quality of the system. The control module is connected to each optical signal processing module, and according to the frequency requirements of the second optical carrier signal, selects and loads the second optical carrier signal that meets the requirements and amplifies it to realize frequency conversion control and frequency hopping switching. The optoelectronic conversion module is connected to the optical signal merging module, and performs optoelectronic conversion on the combined signal output by the optical signal merging module to generate the required down-conversion signal.

[0039] Optionally, as an example, the first carrier module includes an optical frequency comb. The optical frequency comb (Optical Frequency Comb, OFC) is a spectrum composed of a series of frequency components that are evenly spaced and have a coherent stable phase relationship in the frequency domain. These frequency components appear as an optical frequency sequence with equal frequency intervals in the frequency domain, and in the time domain, they appear as an electromagnetic field oscillation envelope with a time width of the order of femtoseconds. This distribution characteristic in the time domain and frequency domain can make the first optical carrier signal of at least one wavelength evenly distributed in the frequency domain, and the frequency interval between adjacent first optical carrier signals is accurately known, so that high-precision measurement can be achieved. On the other hand, the spectrum range of the optical frequency comb is relatively wide, and in the field of communications, multi-wavelength communication can be achieved.

[0040] It should be noted that the first carrier module of the embodiment of the present application includes but is not limited to an optical frequency comb, and can also use a frequency synthesizer, a tunable laser, a laser frequency comb generator, etc., wherein the frequency synthesizer can perform frequency multiplication, frequency division, frequency mixing and other operations on the reference frequency through a phase-locked loop and other technologies to obtain the required frequency signal, and then realize the equal-interval output of multiple frequency signals in the frequency domain through programming and control to meet various application requirements. In the optical field, the frequency synthesizer can be used to generate laser signals of multiple wavelengths, and the laser signal is characterized as a first optical carrier signal, thereby realizing functions such as multi-wavelength communication and spectrum analysis. The tunable laser adjusts the parameters of the laser (such as current, temperature, etc.) to thereby output the frequency of the optical signal, and realizes the equal-interval output of multiple optical signals in the frequency domain through programming and control. The laser frequency comb generator is based on technologies such as a mode-locked laser or an external modulator to directly generate a series of equally spaced discrete frequency components, and the discrete frequency components are characterized as the first optical carrier signal. The setting form of the first carrier module should be selected according to actual needs, and is not limited to this embodiment.

[0041] Alternatively, as an example, Figure 2 FIG. 1 is a schematic diagram of the structure of an optical signal processing module provided according to an embodiment of the present application. Figure 2 As shown, the optical signal processing module includes an optical filter, a first optical intensity modulator, a semiconductor optical amplifier and a micro-ring, wherein the optical filter is connected to the first optical carrier module. As an example, the optical filter can be connected to the first optical carrier module through an optical beam splitter to filter the first optical carrier signals of different wavelengths and only allow the first optical carrier signals of the corresponding wavelength to pass through; the first optical intensity modulator is connected to the optical filter to load the radio frequency signal to be converted on the first optical carrier signal. The semiconductor optical amplifier is connected to the first optical intensity modulator to select and amplify the first optical carrier signal loaded with the radio frequency signal to be converted to obtain the corresponding second optical carrier signal. The micro-ring is connected to the semiconductor optical amplifier to filter the sideband and stray signal operations on the second optical carrier signal loaded with the radio frequency signal to be converted.

[0042] Furthermore, the optical filter includes a fiber Bragg grating. The fiber Bragg Grating (FBG) is a reflective structure that periodically or non-periodically perturbs the effective refractive index. A small amount of light will be reflected at each spatial periodic refractive index change. When the grating period is about half the wavelength of the incident light, all the reflected light will coherently combine into a large reflection with a specific wavelength, so that the wavelength at which the incident light is reflected is called the Bragg wavelength. Light signals of other wavelengths are almost unaffected by the Bragg grating and will continue to be transmitted through the fiber grating.

[0043] It should be noted that the optical filter of the embodiment of the present application includes but is not limited to a fiber Bragg grating, and may also use a Fabry-Perot cavity optical filter, a dielectric film filter, etc., wherein the Fabry-Perot cavity optical filter is composed of two parallel partial reflectors to form a wavelength-selective optical filter cavity. When the incident light enters the cavity, it will be reflected and transmitted multiple times between the two reflectors to form an interference effect. By adjusting the length of the cavity and the reflectivity of the reflector, light of a specific wavelength can be selected for reflection or transmission. The dielectric film filter is a filter formed by alternating superposition of two dielectric films with different refractive indices. Long-wave pass, short-wave pass and band-pass filters are formed by different selections of dielectric films. The dielectric film filter uses the interference principle to select and filter light of a specific wavelength through the reflection and transmission of multiple layers of dielectric films. The setting form of the optical filter should be selected according to actual needs and is not limited to this embodiment.

[0044] Further, the first light intensity modulator includes a Mach-Zehnder Modulator (MZM). The working principle of the Mach-Zehnder modulator is based on the Mach-Zehnder interference effect and the electro-optic effect. When the input light enters the Mach-Zehnder modulator, it is divided into two light waves at the Y-shaped branch at the input end and enters two parallel optical channels respectively. Since the optical channel is made of electro-optical material, when the external applied electrical signal changes, the refractive index of the material will also change accordingly, resulting in a change in the phase of the light wave. When the two light beams reach the Y-shaped branch at the output end, their optical path difference will be different, thereby generating a phase difference. Due to the existence of the phase difference, the two light beams will interfere when converging, and the phase difference information will be converted into the intensity information of the output signal, thereby realizing the modulation of the optical signal. The working wavelength of the Mach-Zehnder modulator covers the C band (the wavelength range of the C band is usually 1530nm~1565nm) and the O band (the wavelength range of the O band is 1260nm~1360nm) of the light wave, and has a wide-band and high-linear working performance.

[0045] It should be noted that the first optical intensity modulator of the embodiment of the present application includes but is not limited to a Mach-Zehnder modulator, and may also adopt a lithium niobate modulator, an electro-absorption modulator, etc., wherein the lithium niobate modulator modulates the phase or intensity of the optical signal by changing the refractive index of the material. The electro-absorption modulator utilizes the absorption characteristics of semiconductor materials to modulate optical signals. When the externally applied electrical signal changes, the absorption coefficient of the semiconductor material changes, thereby achieving modulation of the optical signal; the electro-absorption modulator has high modulation efficiency and low chirp effect, and is suitable for high-speed, long-distance optical communication systems. The setting form of the first optical intensity modulator should be selected according to actual needs, and is not limited to this embodiment.

[0046] Furthermore, the operating band of semiconductor optical amplifiers is between 1.3 microns and 1.6 microns, wherein semiconductor optical amplifiers are optical amplifiers based on semiconductor gain media, and their operating principle is similar to that of semiconductor lasers; the energy band structure of semiconductor materials determines their light absorption and light emission characteristics, and within a specific wavelength range, semiconductor materials can absorb or emit photons, thereby achieving amplification of optical signals. Semiconductor optical amplifiers usually use PN junction devices with strained quantum well structures. The quantum well structure can limit the movement of carriers, thereby improving the optical gain efficiency. By optimizing the structure and parameters of the quantum well, semiconductor optical amplifiers can have higher gain and lower noise in the 1.3 micron to 1.6 micron band.

[0047] Furthermore, the working principle of the microring is based on the interference effect of light. When the phase difference generated by the light wave in a microring is an integer multiple of 2π, the light wave will resonate and output from a specific port, and the microring can tune the working wavelength by adjusting the working voltage. The Q value is an important indicator to measure the performance of the microring. It represents the ratio of the microring's energy storage capacity to the loss. A high Q value means that the microring can store energy more efficiently, has a narrower transmission bandwidth and higher sensitivity. The transmission loss can be reduced and the Q value can be improved by optimizing the microring's size, shape, coupling structure and other parameters.

[0048] It should be added that the number of optical signal processing modules should be set according to the spectrum range of the down-converted signal and the spectrum range of the first optical carrier signal, and the specific setting process will not be repeated here.

[0049] It should be noted that the optical signal processing module can also be set up in the form of application-specific integrated circuit (ASIC. ASIC is an integrated circuit of a proprietary application designed and manufactured for specific user requirements and specific systems. In this embodiment, the integrated circuit is characterized by a stability detection circuit), IP core (English full name intellectual property core, IP core is a mature design of a circuit module with independent functions in chip or integrated circuit design. The circuit design can be applied to other chip or integrated circuit design projects containing the circuit module, thereby reducing the design workload, shortening the design cycle, and improving the success rate of chip or integrated circuit design. IP cores are classified into three levels: behavioral level, structural level, and physical level, and thus correspond to three types of IP cores, which are soft cores designed with hardware description language, solid cores that complete structural description, and hard cores based on physical description and process verification. The specific setting forms are not described here one by one. As long as the first optical carrier signals can be screened and modulated and amplified to generate corresponding second optical carrier signals, any setting form of the optical signal processing module is applicable, and is not limited to this embodiment.

[0050] Optionally, as an example, the second optical carrier module includes a laser and a second optical intensity modulator, wherein the laser can generate a local oscillator optical carrier signal; the second optical intensity modulator is connected to the laser, and loads a local oscillator radio frequency signal to the local oscillator optical carrier signal to generate a third optical carrier signal, thereby realizing the transmission of information.

[0051] Optionally, as an example, the photoelectric conversion module includes a photodetector. The working principle of the photodetector is mainly based on the photoelectric effect. When light is irradiated on a semiconductor material, photons will hit electrons in the semiconductor material, causing it to transition to the conduction band, thereby forming holes and electron pairs. This effective carrier pair (electron-hole pair) will move in the semiconductor and form a current when a bias is applied externally, thereby realizing the conversion of optical signals into electrical signals to generate the required down-conversion signal.

[0052] In the present application, a first optical carrier signal of at least one wavelength is generated by a first optical carrier module, so that the first optical carrier signal has a wideband function; each first optical carrier signal is screened, loaded with a signal to be converted and a signal compensation operation is performed by an optical signal processing module to ensure that the loss of the first optical carrier signal during transmission is effectively compensated, and a second optical carrier signal with high gain and high rate is obtained; the on and off state of the optical signal processing module is controlled by a control module, and the gating state of each second optical carrier signal is adjusted to enable the second optical carrier signal to complete the frequency hopping operation; a third optical carrier signal loaded with a local oscillator radio frequency signal is generated by a second optical carrier module, and the third optical carrier signal and each second optical carrier signal are combined, and then the combined signal is subjected to a photoelectric conversion operation by a photoelectric conversion module to obtain the required down-conversion signal, so that the microwave photon frequency hopping device completes the frequency conversion operation. The frequency hopping and frequency conversion functions are integrated in the same microwave photon frequency hopping device, and the seamless connection and efficient coordination of functions are achieved through the generation of optical carrier signals, optical signal processing, beam combining, signal gating and photoelectric conversion. It has the advantages of flexible regulation, fast switching speed and high integration, and has a wide range of application scenarios.
