In January, 2020, his researchP on magnetic focusing Hall thruster won the 2nd prize of the National Scientific and Technological Progress Award.

The Hall thrusters developed by Russia and America suffer from the problem of large plume divergence angle, which leads to high energy ion bombardment on the thruster channel and solar panel. The thrust, specific impulse, and lifetime of the propulsion platform are largely reduced.

In the past decades, Professor Yu Daren and his team focused magnetic focusing technology, and made a new generation of Hall on solving the above problem. They proposed a theory on thruster. In November, 2016, this thruster was adopted on the SJ-17 .S. News & World Report announced the controlling the plasma plume of the thruster and on-orbit satellite.

RESEARCH & ACADEMIA ULTRAFAST CONTROL OF VORTEX MICROLASERS

n February 28th, 2020, Professor Song or nano-cavity. This works very well at the beginning. The Qinghai’s research group from Harbin relative high Q factor of a resonator can effectively increase Institute of Technology, Shenzhen, the local electromagnetism, but the corresponding mode reported an ultrafast control mechanism for lifetime (τ∝Q/ω) also restricts the response of the switch. microlasers, which applied the concept of The other techniques with ultra-small effective mode boundedO states in the continuum (BICs), breaking the long- volume, such as plasmonic nanostructures, are limited by standing trade-off between ultralow energy consumption the huge coupling and the propagating loss. and ultrafast switching. The research paper titled “Ultrafast Professor Song’s group has been working on the Control of Vortex Microlasers" was published in Science. microlasers to solve the above trade-off. They focus on laser An all-optical switch is a kind of device that controls light emissions from the topologically protected BIC. Compared by light, which plays an essential role in next-generation with accidental BIC, the topologically protected BIC is quantum computing and quantum information. In past extremely sensitive to symmetry-breaking perturbations. decades, the requirements for all-optical switches have been As a result, both the gain of materials and the symmetry categorized as low energy consumption, high speed, strong become key parameters to control. Owing to the far-field modulation ratio, small footprint, and on-chip integration. characteristics of BICs, the transition from BIC microlasers The small foot-print and on-chip integration are quite to conventional lasers represents a re-distribution of the easy for current nanotechnologies. However, the trade-off laser emission instead of a direct switching on/off of the between low energy consumption and high speed is a severe lasing mode. This makes the switching process is not challenge. The conventional approach focuses on enhancing limited by the lifetime of resonant mode. Since the BICs the light-matter interaction via on-chip integrated micro- can eventually have infinitely large Q factors, the laser

thresholds can be reduced by orders of magnitude. In this sense, the BIC microlaser can break the trade-off between low energy consumption and high speed. Therefore, it is possible to realize the ultrafast optical switching that matches all the requirements of modern classic and quantum information.

In square-latticed MAPbBr3 perovskite periodic nanostructure, the researchers have realized single mode laser emissions with donut beam profiles. As expected, they have confirmed the relationship between the symmetry of the pumping profile and the emission beam profile.

of extensile/contractile bending and helical Pneumatic Artificial Muscles (PAMs). Through the establishment of mathematical models and performance characterization experiments, the authors systematically analyzed and studied the axial, bending and helical PAMs via three-dimensional curved surface clusters and provided a reference map for the designers and researchers.

A soft manipulator with multiple degrees of freedom inspired by an elephant trunk was developed to explore the potential application of bending and helical PAMs. A contractile PAM has a large output or load capacity, while extensile PAM can produce more deformation. So according to the output characteristics, the researchers used a contractile PAM in the first section to bear the maximum load, and extensile PAM in the second section to provide a wider range of motion. Meanwhile, the helical PAM was mounted at the end to grasp objects in a way that mimics the movements of PAMs inspired by the elephant trunk the elephant trunk.
