In a new publication from Opto-Electronic Advances the research group of Professor Xiong Wei, from Huazhong University of Science and Technology, Wuhan, China, discuss recent advances in optical ...

Optical anti-counterfeiting technology, as a preventive measure, has deeply permeated our daily lives. Visually readable codes designed based on optical materials are widely used due to their ease of ...

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...

Advancements in photonic integration demand high-speed, precise dynamic light field control and large-capacity information processing capability. As subwavelength artificial structures, metasurfaces ...

Dynamic bandwidth allocation (DBA) lies at the heart of modern optical access networks, ensuring that upstream capacity is assigned to multiple users or services in real time. In a typical passive ...

Natural compound eyes (NCEs) were first investigated by Robert Hooke in 1664 after he observed orderly arranged pearls in the cornea of a grey drone fly. These NCEs then inspired the development of ...

Whether it is routing traffic across telecom core networks, enabling real-time AI inference, supporting lawful intercept ...
