Responsivity of Photodetector = Photocurrent/Incident Power
R = I_p/P_o

Why is responsivity an essential parameter when evaluating photodetectors for specific applications?

Responsivity is a crucial performance metric for photodetectors as it quantifies their sensitivity to incident light and their ability to efficiently convert light into electrical signals. A higher responsivity indicates that a photodetector can detect even weak optical signals, making it essential in applications where precise measurements are required.
