Summary: We propose and demonstrate a Lidar beam-forming scheme using wavelength-division-multiplexing (WDM) and time-division-multiplexing (TDM), which eliminates the need for moving parts. The scheme achieves beam formation by demultiplexing lights with different wavelengths into N waveguides (WDM channels) and further switching them into M waveguides (TDM channels) to point in different directions. We have successfully demonstrated the scheme using 4 WDM channels and 1 x 4 optical fiber switches, together with time-of-flight (ToF) technique for distance measurement. This combined TDM and WDM scheme offers an attractive alternative to existing beam scanning methods.

Summary: This article proposes a novel multipoint gas detection scheme based on the photothermal effect and interferometer. By incorporating fiber Bragg gratings with different central wavelengths in the interferometer, gas concentration information can be extracted from different gas cells, enabling simpler and more efficient installation. The experiment validates the effectiveness of the method in reducing noise and crosstalk, and demonstrates successful acetylene detection.

Summary: This study proposes a triple-band transmission system using only C-band transceivers and all-optical wavelength conversions. By employing silicon-rich nitride waveguides, wavelength conversion can be achieved on photonic integrated circuits with superior performance. Through the design and demonstration of the SRN waveguide, the feasibility of this method in wideband transmission systems is shown.

Summary: A novel 1 x M fold-back type wavelength selective switch (WSS) is designed to have fewer waveguide crossings, reducing excess crosstalk and loss in lightwave circuits. By using a fold-back architecture, the number of crossings can be reduced to less than half of a conventional design, improving performance and scalability. The switching operation of a 200-GHz spacing, 20-channel, 1 x 2 silicon WSS in a fold-back configuration is demonstrated, showing promising results with average insertion loss and extinction ratio.

Summary: In this paper, a new design of grating couplers (GCs) is proposed to overcome the limited optical bandwidth of traditional GCs caused by the wavelength's dependency on the coupling angle. This device combines a dual-broadband achromatic metalens (ML) with two focusing GCs to achieve excellent dual-broadband achromatic convergence. The ML-assisted GCs device exhibits a good broadband property, improving the coupling of spatial light with a wide spectrum.

Summary: This paper analyzes the angle drift error of the hemispherical resonator gyro caused by electrical unbalance in whole angle mode operation and proposes a single-channel control strategy to address this issue. The strategy can effectively eliminate drift error, reduce the cost and size of the control system, and promote the miniaturization of the gyro.
