Fig. 6. Photodetection to NIR and visible light.
LDR characteristics measured for the dual-mode OPD operated in the presence of (A) NIR light (770 nm) and (B) visible light (460 nm) sources at different reverse and forward biases. (C) Time-dependent photoresponses measured for a dual-mode OPD operated in the presence of the NIR light (770 nm) and visible light (460 nm) sources.
