Abstract
A light detecting device includes a first section including a first substrate, and the first substrate includes a compound semiconductor layer configured to convert light into an electrical signal. The light detecting device includes a second section including a second substrate, and a third section including a third substrate. The second substrate includes a first amplifying circuit that amplifies the electrical signal, and the third substrate includes a second amplifying circuit and a selection circuit. The first, second, and third sections are stacked with the second section being between the first section and the third section.
