Visible light, the range of the em spectrum that human eyes can detect, occurs between 400 THz and 700 THz. Just outside of the visible range on the red end is the Infrared range, and just outside on the violet end is the ultraviolet range. There is not a sharp boundary, just as ...
The target device achieves an ultrafast response of 19.7/18.3 ns in the frequency-selective photoresponse range 0.8–9.7 MHz. This anti-interference photodetector can accurately transmit character and video data under strong light interference with a source intensity of up to 454 mW cm...
