Is the outside of the active area completely insensitive to light?
No. Irradiated light on the non-active area adjacent to an active area may generate a small photocurrent in the detector. The magnitude of this signal is dependent of many parameters such as the wavelength of the radiation, the applied bias, and the amount of incident light on the active area as well as distance from the active area.
