Dual-band UV/VIS photodiodes for sensing applications

In this paper the construction and technology of the dual-band UV-VIS photodetector has been shown. The designed and manufactured device allows for parallel monitoring of a single signal path in two different optical bands. The presented device consists of two independent photodiodes, the first of them is developed silicon carbide diode working in UV range, and the other one can be any VIS photodiode available commercially.
