Summary: This study demonstrates all-optical wavelength conversion using cascaded four-wave mixing (FWM) phenomena with graphene oxide (GO) and a highly nonlinear fiber (HNLF) device. The experimental results show that GO, with its strong third-order nonlinear effect, is an excellent material for nonlinear optical wavelength conversion. The amplification of HNLF and GO, along with the group velocity matching of pump and signal, promotes the cascaded nonlinear frequency mixing process. The maximum spacing between signal and pump is found to be 21 nm, and the order of cascaded FWM light increases as GO increases, leading to a maximum first-order FWM conversion efficiency of -14.5 dB. This is the first investigation of cascaded FWM-based all-optical wavelength conversion in HNLF-GO with wide wavelength selectivity, providing a new approach for fabricating high-performance nonlinear optical devices.

Summary: This paper introduces a novel integrated photonic CNN based on double correlation operations and time-wavelength modulation. Testing on the MNIST dataset shows an accuracy of 85.5% for the photonic CNN, slightly lower than 86.5% achieved by a 64-bit computer. The study also analyzes the computing error of the photonic CNN and proposes a parallel photonic CNN based on a tensor processing unit.

Summary: We propose an all-optical wavelength converter for the mid-infrared spectral range with enhanced conversion efficiency. A highly nonlinear MXene-decorated microfiber is used as the conversion medium, and the device combines the advantages of two-dimensional MXene materials and tapered microfiber to promote conversion efficiency. The experimental results show a significant conversion efficiency at 2.05 mu m wavelength, with a tunable range of 17 nm and stable efficiency fluctuations within 1 dB during testing.

Summary: This paper proposes and experimentally investigates a simple and highly efficient four-channel all-optical wavelength conversion method based on the four-wave mixing effect of the directly modulated three-section monolithically integrated semiconductor laser. The wavelength spacing can be adjusted by tuning the bias current of the lasers to be 0.4 nm (50 GHz). Experimental results demonstrate that a 50 Mbps 16-QAM signal centered at 4-8 GHz can be successfully switched to a targeted path, with up or down conversion depending on a wavelength-selective switch and a conversion efficiency of up to -2 to 0 dB. This work provides a new technology for photonic radio-frequency switching matrix and contributes to the integrated implementation of satellite transponders.

Summary: In this paper, an all-fiber single- and dual-wavelength tunable CVBs fiber laser using the nonlinear optical saturation absorption characteristics and filtering properties of nonlinear multimode interference (NL-MMI) is reported for the first time. The experiment demonstrated the ability to tune the central wavelength of the mode-locked CVBs fiber laser in both single- and dual-wavelength configurations. This NL-MMI-based wavelength-tunable ultrashort pulse CVBs fiber laser has great potential in optical communication.
