A layered graphene and chromium oxychloride device functions as a broadband optical synapse, detecting visible to deep infrared light and learning image orientation through built-in memory. (Nanowerk ...
These ultra-thin materials exhibit unique quantum and electronic properties not found in conventional bulk materials. Their atomic thinness allows precise control over their structures and properties ...
From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...
Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...
The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...
