摘要

Light filtering in a-SiC:H stacked multilayer devices is analyzed, using the Laser Scanned Photodiode technique. Results show that the p-i-n-p-i-n device, under appropriated read-out voltages, behaves itself as an imager and a filter giving information not only on the position where the optical image is absorbed but also on its wavelength and intensity. Identification of the red, green and blue components of the spectrum and simultaneous image recognition were achieved at read-out voltages that are able to cancel the self-bias effect due to the different light penetration depth. These voltages shift from positive to negative values as the wavelength of the impinging photons across the back absorber increases. A numerical simulation supports the color filter analysis.
