Sub‐1 ms Optoelectronic Synapse Based on {ZnCdO/ZnO} Multilayer Structure for High‐Speed Neuromorphic Vision Systems

Advanced Functional Materials, EarlyView.
Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

Study on Characteristics of Coupled-Core Four-Core Fibers With Different Core Pitches

IEEE Photonics Journal
We studied the characteristics of coupled-core four-core fibers (CC-4CFs) with different core pitches both theoretically and experimentally. The spatial mode dispersions of different fibers were analyzed, and the result agrees well with theoretical ones.

All-optical indoor wireless communication system

, 2016
We present a transparent all-optical wireless architecture for full-duplex two-dimensional beam-steered communication system with wavelength reuse. We compare the performances of symmetric (down 10 Gbit/s / up 10 Gbit/s) and asymmetric (down 10 Gbit/s ...
