logic operations, and buffering, are still lacking in practically usable forms. It is still challenging to improve the optical device performance for practical applications, including reducing footprint size, required optical power levels, and device performance regarding nonlinear transfer characteristics. Wavelength conversion between adjacent channels is one of the essential functions in advanced optical networks. As a crucial component in the optical communication system, alloptical wavelength converter should be with advantages of high speed, bit rate transparency, low chirp, and no extinction ratio degradation. [4,5] Wavelength conversion in the optical system was typically realized by utilizing the parametric nonlinear optical effect, including cross gain modulation (XGM), [6] four-wave mixing (FWM), [7][8][9][10][11][12][13] and cross phase modulation (XPM) effect. [14,15] These nonlinear optical wavelength converters were typically realized in semiconductor optical amplifiers (SOA). [6] By using the SOAs, the XGM-based method is highly power efficient and polarization independent but suffers from high extinction ratio degradation. Besides, only converted signal can be obtained in the desired wavelength through the XGM-based method. The XPM-based method can convert signal to the target wavelength with converted signal into a SOA-Mach-Zehnder interferometer structure. [16] However, the input power of the XPM-based method is limited in a certain range and has to be integrated. FWM method is attractive because it is transparent to modulation format and capable of transmitting high bit rate signals. [6] FWM methods typically suffer from low conversion efficiency and fast decrease on efficiency as wavelength span increases. Researchers have also investigated other nonlinear optical methods to realize the wavelength conversion, such as highly nonlinear optical fiber, [17] nonlinear optical loop mirror, [18] optical filtering, [19] or based on time-domain holography [20] and so on. These previous methods suffer from high cost, unstable, bulky, or difficult to be compatible in the fiber system.In the last decade, novel materials-based optical devices are considered as an effective solution. Silicon was considered to be with great potential in the optical signal processing system as it is transparent at the near-and mid-infrared telecommunication regime and with high nonlinearity. [21][22][23][24] Silicon waveguides have been reported as optical wavelength converter in the photonic signal processing system. [25,26] For the all-optical applications utilizing the third-order nonlinear properties of Optical signal processing based on 2D materials is a hot topic which has attracted rising interests. As a novel class of 2D material, MXene is becoming a promising nonlinear photonics material. In this contribution, MXene Ti 3 C 2 T x , prepared by liquid acid etching method, is developed as a novel all-optical device by depositing on a microfiber, which shows an excellent nonlinear optical response at the telecommunicati...

“…Therefore, specific media could be selected to meet the corresponding demand. For example, SOA-based FWM has the advantages of simple structure, high conversion efficiency, low cost, and easy integration; [7] the HNLF has the advantages of short response time, almost unlimited conversion rate, and simultaneous frequency conversion of multiple signals; [8] the silicon-based waveguide has the advantages of simple structure, low noise, wide bandwidth, and easy integration; [9] By enhancing the nonlinear effect of the medium, it is also possible to realize FWM in a short length of the fiber. However, the generated idler light is low in power.…”

With the increase of data volume and the shortage of frequency band resources in sub6 band, it is difficult to meet the communication requirements for the existing mobile communication systems. It is worth noting that, the 5G millimeter wave communication technology has the advantages of fast speed, large bandwidth and low delay, which can meet the demands of future mobile communication. How to generate millimeter wave with high quality is the key technology. In this paper, 5G millimeter wave communication systems and several all-optical millimeter wave generation technologies are discussed, including direct modulation method, optical heterodyne method, frequency up-conversion method, external modulation method and four-wave mixing (FWM) method. Furthermore, the advantages and limitations of different methods are compared and analyzed. In addition, the promising future applications of 5G millimeter wave communication systems are discussed, and the potential application value of 5G millimeter wave communication systems in digital twin, mobile edge computing and other fields is summarized.

In this work, we report the use of different waist diameters of tapered fiber to generate a four-wave mixing (FWM) effect. The FWM conversion efficiencies obtained from the tapered fiber with 10 µm, 20 µm, and 30 µm waist diameters were −37.81 dB, −38.50 dB, and −39.01 dB, respectively, at 1.584 W pump power. The FWM-based outputs were stable over a 60 min measurement at a 1.5 µm wavelength operation, with a small fluctuation range of 0.21 to 0.45 dB. Furthermore, the setup could generate the FWM effect with a maximum tuning range of 9.5 nm (10 µm and 20 µm) and 9.0 nm (30 µm). The numerical simulation results showed a high nonlinearity at the air-cladding region when the tapered waist diameter was reduced. These characteristics of the tapered fiber can be used as an excellent medium for studying nonlinear phenomena, which could result in the development of new photonic devices for high-power optical communication.
