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...

Using the micro-ring resonator (MRR) system, the single and multi-carriers at frequencies of f(1)=192.898, f(2)=192.990, f(3)=193.1, f(4)=193.315, and f(5)=193.537 THz with a free spectral range (FSR) of 92, 110, 215, and 222 GHz, respectively, are generated to be suitable for a radio-over-fiber (RoF) system based on multi-input multi-output (MIMO) with orthogonal frequency division multiplexing (OFDM). Demonstrated are the concepts of all-optical MIMO signal generation and its transmission over a 50 km single mode fiber (SMF) optical link and an up to 3 m wireless link. Sixty-four multi-carriers are used in the all-optical generation of three MIMO W-Band RF signals, where the single carriers (f(3)-f(5)) transport the signals over the RoF link. The bit error rate (BER) of the overall system performance is discussed; thus, the transmission of MIMO signals is feasible for up to an SMF path 50 km long and a wireless distance of 3 m.

“…The push-pull configuration is able to speed up the switching time of the device allowing sharper transitions and reducing pattern effects [39]. The relative delay between the push and pull signals opens a switching window over the probe signal allowing the transfer of the intensity modulation from the input signal over the probe [40].…”

A novel optical node architecture based on all-optical traffic grooming for flexible optical networks is proposed as a mean to utilize the optical spectrum flexibly. In this work, we have overcome the key technical challenge towards implementation of the node architecture by designing and experimentally evaluating a fully flexible intelligent optical node. The proposed solution has the potential to deal with simultaneous multi-functional degree of switching such as format conversion, wavelength conversion, multicasting, spectrum defragmentation and time-domain grooming capability in order to maintain efficient resource utilization. The field experiment was also performed on original and converted channels over a 110-km dark fiber link with the aim of proving the signal robustness in a real network scenario. Finally, BER measurements experimentally demonstrate efficient adaptive switching and processing of variable fragmented traffic, leading to improved network scalability and efficiency
