We proposed 1:9 and 1:99 optical power couplers based on inverse designed nano-pixel. Both couplers occupy a compact area of 2.88 × 2.88 μm2 with a low excess loss of 0.68 (1:9) / 0.41 dB (1:99) and a wide wavelength operation range of 1500-1600 nm.

Two machine learning models, including the polynomial regression model and artificial neural network, are proposed based on the result of a visual perception experiment of fluorescent samples. The results indicate that both two models can ideally predict the visual color appearance of fluorescent samples under various lighting conditions with high R-squared, acceptable RMSE, and MAE values.

In this article, we propose a concept which is the D-shaped silicon core fiber sensor based on surface plasmon resonance within the Mid-IR range. Au layer coating on the D-shaped side-face of silicon core fiber acts as a plasmonic active metal. By using the limited element methods, the sensing properties of the proposed sensor are investigated, and an average sensitivity up to 2.931 μm/RIU is obtained for the analyte of different refractive indices varies from 1.20 to 1.55. In addition, the Au coating layer and analyte are placed on the D-shaped side-face of the proposed fiber sensor; hence, this structure does not need to fill the voids. Thus, it is easy to fabricate and put to use. Also, the wavelength band in 2-μm is far from optical communication band, which means the proposed sensor could be connected with fiber network without any influence and crosstalk.

We investigate the practical benefits of multi-band optical networks leveraging distance-adaptive resource allocation. Simulations clarify that the S+C+L-band scenario can successfully accommodate three times more traffic than a single-band scenario even on a large-scale network.

We investigate the reason why the artificial neural network-based demodulators for optical eigenvalue modulated signals show a BER improvement compared with conventional demodulators. Both nonlinear and high-dimensional classifications in eigenvalue-domain contribute to the BER improvement.

Spot size converter by using nano-pixels waveguide is proposed especially, to enhance the vertical, not only the lateral, field confinement. Theoretical analysis shows a coupling efficiency of -0.6 dB at λ0=1.572 μm by combining the design SSC of a nano-pixels waveguide of 30 nano-pixels (1×2 μm2) and SiO2 window structure.
