Inspired by human brain for multi-task continual learning, a generalized photonic neuromorphic architecture (L2ONN) is proposed to model physical-driven light sparsity and parallelism, towards reconfigurable and scalable lifelong learning.
We report a light-controlled soft bio-microrobots (called “Ebot”) based on Euglena gracilis that are capable of performing multiple tasks in narrow and changeable microenvironments with high controllability, deformability and adaptability.
We demonstrate free-space coupling to microtoroids using one objective to excite and collect scattered resonant light. We achieve Q-factors > 108 and perform sensing with an SNR > 26 dB.
We developed a geometric approach to identify highly anisotropic materials. This leads to the discovery of giant anisotropy of As2S3, enabling the record-small quarter-wave plate.
A time-domain excitation strategy for stimulated Raman scattering was achieved by manipulating vibrational wave packet interference. The new method enables simultaneous sub-mM level sensitivity and natural-linewidth-limit Raman spectra.
This special issue covers the fundamentals and applications in THz optics and photonics, presents the basic research overview or cross-cutting interdisciplinary research contributed from the most active groups in eight countries, and serves as most updated references and detailed guidance for the active researchers in the THz photonics community.
