Abstract Long-wave infrared (LWIR, 6–14 µm) is an important wavelength range as it covers abundant vibrational molecular fingerprints that can be used for gas/liquid sensing and absorption spectroscopy. Silicon waveguide-based passive photonic devices that offer advantages toward chip-scale miniaturization of photonic integrated circuits (PIC) and photonic sensors in LWIR have been explored. However, the modulation of Si-based guided-wave propagation in LWIR remains less reported. Here, we demonstrate a MEMS tunable directional coupler operating at a long-wave infrared wavelength range (6.4–7 µm) using suspended Si waveguides with subwavelength gratings. Leveraging the membrane transfer technology, the whole photonic waveguide device membrane is transferred onto a receiver substrate with a cavity that allows sufficient displacement for MEMS electrostatic actuation. The proposed device experimentally achieved an optical attenuation of −14.25 dB with 90 V DC bias voltage, while having a response time of 177 µs. In addition, the demonstration of using such a device for computational spectroscopy has been validated.
摘要长波红外(LWIR,6-14 µm)是一个重要的波长范围,因为它涵盖了丰富的振动分子指纹,可用于气体/液体传感和吸收光谱。基于硅波导的无源光子器件在LWIR中为光子集成电路(PIC)和光子传感器的芯片级小型化提供了优势。然而,硅基导波在长波红外中的调制仍然很少报道。在这里,我们展示了一种在长波红外波长范围(6.4–7 µm),使用具有亚波长光栅的悬浮Si波导。利用膜转移技术,将整个光子波导器件膜转移到具有空腔的接收器基板上,该空腔允许用于MEMS静电致动的足够位移。所提出的装置通过实验实现了−14.25的光学衰减 dB,90 V DC偏置电压,同时具有177的响应时间 µs。此外,使用这种设备进行计算光谱学的演示也得到了验证。

Abstract The application of automatic inspection plays an important role in improving the quality of industrial products. Aiming at nodules on the surface of electrolytic copper plate, this article introduces a comprehensive optical online inspection method. In order to obtain dynamic information of product and overcome the interference of random factors such as large-curvature deformation, position deviation and tilt, the system integrates a variety of single technologies including digital moiré, image recognition and spatial transformation. The online test results show that the system can effectively extract the information of nodules and automatically classify the products according to the set threshold.

Abstract In this paper, a horizontal and vertical double-slits interferometer using visible light are designed to measure the transverse beam size of Hefei Light Source II (HLS-II). For the given initial structural parameters of the two interferometers, a series of numerical simulations and analyses are carried out by using the Synchrotron Radiation Workshop (SRW) code. Furthermore, the core parameters of the double-slits components in the interferometers are optimized. In the end, the visibilities of the horizontal and vertical interferometer we designed are 0.345 and 0.548 respectively, which are in the range of 0.2–0.6. And simulation results meet the requirement of theoretical relative measurement error of less than 10%.

Abstract Spatial pose estimation devices for mobile and cable-suspended robots have been rapidly developed. The HTC Vive sensor, which operates with swept laser beams, has aroused many researchers’ interest. We present experiments with a double pendulum robot equipped with the HTC Vive Tracker. A linear feedback controller ensured the tracking of pre-defined end-effector trajectories of various speeds. The pose feedback of the controller was provided by the HTC Vive. As a reference, the realized trajectory was measured by the OptiTrack motion capture system. We report that the motion control of a spatial double pendulum robot can be achieved by using a linear feedback controller together with cable winch and fan actuators providing six independent inputs. The accuracy of the HTC Vive was proved to be sufficient for the feedback position control of indoor mobile robots. We report that the error strongly correlates with the linear/angular velocity, the acceleration and the jerk.

Abstract A bionic artificial compound eye manufactured on a concave mold with precision engraving method for imaging, which allows for the rapid fabrication of large-scale compound eyes at a low cost. Thousands of concave structures are accurately machined and positioned omnidirectionally in concentric rings with a minimum diameter of 100 μm on a hemisphere. The PDMS ommatidia can be obtained once replicated, which can greatly improve preparation efficiency, and the peel-off process can also be optimized by alcohol ultrasonic without edge damage. The optical performance and field of view of the artificial compound eye are also investigated, and the experimental results are around 120°. Furthermore, the combination of the prepared compound eye and the commercial CMOS camera successfully captures images of different shapes.

Abstract Surface-enhanced infrared absorption (SEIRA) spectroscopy is a powerful technique that overcomes the issue of low molecular absorption cross-sections in infrared spectroscopy. Due to the collective oscillations of electrons in the infrared regime, SEIRA using resonant metamaterial provides greatly enhanced (up to 107) electromagnetic fields extending up to tens of nanometers from the metamaterial. The enhanced near-field enables spectroscopic analysis and ultrasensitive on-chip sensing of molecules. This interesting characteristic has aroused widespread attention from researchers to SEIRA technology, and various SEIRA-based sensing applications have been continuously emerging. Optimization of the signal enhancement to obtain high sensing performance is the developing main thread of SEIRA technology. In this Review, we provide a basic understanding of SEIRA’s sensing mechanism and theoretical model. With this background, several SEIRA optimizing methods are discussed, ranging from design, materials to algorithms. Additionally, perspectives about the future development trends of SEIRA technologies are discussed.
