We report on current theoretical and experimental results of echo pulses based on ultra-weak Fiber Bragg Gratings (uwFBGs), using intensity compensation to solve the signal distortion caused by light pulse delay. Cubic Spline Interpolation is applied, leading to better robustness for the interference intensity. Then the linear compensation value is obtained by comparing the peak intensity in order to correct attenuation in three-way optical path. We report improvements over the conventional demodulation algorithm based on 3×3 coupler with circulator. The experimental results have shown that, when the intensity reduction is existed due to pulse delay, the hydroacoustic field could be reconstructed with high fidelity by using the proposed method. Leading to much lower noise density level for the interference pulse intensity, more than 7 dB when the reference signal is 1rad/√Hz in 5~50 Hz, and the SNR is improved approximately 10 dB@10 Hz. The proposed method exhibits a particularly applicability in passive optical path, which is of great importance for increasing the practicality of the system in complicated environments.

We simulated InGaAs/InP Modified Uni-Traveling-Carrier Photodiodes (MUTC-PDs) with different reverse bias voltages under high optical power injection, using a commercial device level simulator Apsys. By optimizing the absorber layer structure and the operating voltage, this work achieved an MUTC-PD design with an opto-electric responsivity of 0.16A/W and over 300GHz 3-dB bandwidth under 10 mW/µm2 optical injection density.

Improving the environmental adaptability of laser system is the key to realize field measurement for cold atom interference gravimeter. In this paper, a laser system based on a 1560nm fiber laser is described in detail. The output power of trapping laser and Raman laser are 1.1W and 1.9W at 780.2nm, with near-ideal Gaussian mode of TEM00, respectively. Using this compact optical scheme, we achieved the atom gravimeter interference with 2T=140ms, corresponding to an acceleration sensitivity of 610μGal/√Hz, which is limited by vibration conditions. The results of optical frequency locking and power stabilization for laser system meet requirements of high precision mobile gravimeter.

In recent years, supervised deep learning of image denoising has attracted extensive research interests. Those methods usually required numerous pairs of noisy image and its corresponding clean image in training processing. However, in most real situations, it is hard to collect high-quality clean images such as optical coherence tomography (OCT) images. Therefore, it is of great significance to study a effective de-noising network without clean images for supervising, which is only trained with noisy image. In this article, for a single OCT image, we propose a self-supervised deep learning model called Self2Self-OCT network by improved the Self2Self network and added a loss function that can effectively remove the background noise of OCT images, which makes the whole training do not need correlative clean images. Specifically, we use gated convolution to replace the partial convolution layer of the encoder’s block in Self2Self. The input image and its Bernoulli sampling instance are put into our network respectively, and the background noise attenuation loss is added to loss function during training. The result is estimated based on the average value of multiple prediction outputs. The experiments with different OCT images indicate that proposed model not only has obvious advantages compared with the existing single deep learning methods and non-learning methods, but also surpasses the supervised learning of a small number of sample training.

Massive real-time image test results put forward higher requirements for network transmission and intelligent technology. Intelligent detection technology using 5G network has become one of the most important research directions of multi-spectral optoelectronic devices. However, they are still confused about the architecture of the 5G network and how to design the system with unmanned control for different user needs. At present, it is urgent to solve how to overcome the instability of 5G optoelectronic device network structure through multi-spectral segments, achieve high-quality transmission of results, and obtain intelligent optimal results. This paper summarizes the configuration and mode of 5G network, application system of multispectral optoelectronic devices. This paper also analyzes the intelligent detection system based on 5G scheme.

Optical coherence tomography angiography (OCTA) for blood vessel 3-D structure imaging suffers from blood vessel tail artifacts when using a long decorrelation time (e.g., repeat B-scan acquisition in regular OCTA) or loss of micro vessel signal when using a short decorrelation time. In this work, we developed an adaptive first order field autocorrelation function (g1) analysis-based technique to suppress the tail artifacts under macro vessels while enhancing the dynamic signal of micro vessels. The proposed method is based on the differences of the decorrelation rate and the phase variations of g1 between the vessel voxels and the artifacts regions. A short or a long decorrelation time was applied to obtain the dynamic index of the tail artifacts region or the blood vessel region, respectively. Compared to the post image processing-based techniques, the proposed approach addresses this problem through the physical basis and shows a good performance in suppressing the tail artifacts while enhancing the detection of the micro vessels.

Optical performance monitoring (OPM) technology, especially the optical power and OSNR of each WDM channel, are of great importance and significance that need to be performed to ensure stable and efficient operation and maintenance of network itself. In this paper, we present our recent research activities and progresses on optical-label enabled OPM. Simulation results of WDM system show that the maximum error of channel power monitoring and OSNR estimation are less than 1dB after 20-span transmission. It confirms that the optical-label enabled OPM has lower cost and higher efficiency for mass deployment in practical WDM networks.

Due to the advantages of optical circuit switching (OCS), all-optical interconnects (AOIs) for data center networks (DCNs) have attracted intensive interests recently. Hyper-FleX-LION is a highly-flexible AOI architecture that operates with the OCS based on wavelength-division multiplexing (WDM). In this paper, we present our recent research activities on Hyper-FleX-LION. First, to prove the superiority of Hyper-FleX-LION, we enumerate various communication patterns of distributed machine learning (DML) in DCNs, and analyze the acceleration effect achieved by Hyper-FleX-LION over existing interconnect architectures, such as the hybrid optical/electrical interconnect based on optical cross-connect (HOE-w/OXC). Results show that Hyper-FleX-LION can better accelerate the tasks of DML. Then, we classify network applications in DCNs as bandwidth-intensive and data-intensive ones, and analyze the operational costs and task completion time that Hyper-FleX-LION brings to them and how to optimize the topology design and traffic routing of Hyper-FleX-LION adaptively. The Analysis results confirm the importance of designing an application-aware configuration scheme for Hyper-FleX-LION.
