Bidirectional optical signal transmission between two identical devices using perovskite diodes

The integration of optical signal generation and reception into one device—thus allowing a bidirectional optical signal transmission between two identical devices—is of value in the development of miniaturized and integrated optoelectronic devices. However, conventional solution-processable semiconductors have intrinsic material and design limitations that prevent them from being used to create such devices with a high performance. Here we...
