Schematic of the metasurface-based light-to-microwave transmitter. (IMAGE)
Caption
The metasurface platform is realized by integrating a high-speed and high-sensitivity photoelectric detection circuit into the back of a programmable microwave metasurface, where the reflection spectrum of metasurface can be manipulated by the light in real time, thus realizing the direct light-to-microwave signal conversion. By further using the dispersion characteristics of the metasurface, one designed light intensity signal can be converted directly to two different microwave signals. With this metasurface-enabled transmitter, a dual-channel light-to-microwave wireless link is built up, in which two different videos can be transmitted and received simultaneously and independently.
