This is a unique photo detector with two vertically stacked P-N junctions on a single silicon chip. One junction is response enhanced for blue/visible light, the other enhanced for red/near IR.
This is a unique photo detector with two vertically stacked P-N junctions on a single silicon chip. One junction is response enhanced for blue/visible light, the other enhanced for red/near IR. Monochromatic light between 480nm and 850nm generates different amounts of photocurrent in each junction. This produces a unique photocurrent ratio that can be correlated to the exact wavelength of radiation.
