Abstract:
A light-receiving element array, comprising:a plurality of pin-photodiodes arrayed in a straight line, each of the pin-photodiodes being formed by crystal growth on a first conductivity-type of substrate, and constituting a mesa and waveguide-structure with the pin-photodiodes being isolated from each other by isolation trenches; a first conductivity-type of electrode formed on the bottom surface of the substrate; and a plurality of second conductivity-type, opposite to the first conductivity-type, electrodes being formed on top surfaces of respective ones of the plurality of pin-photodiode; wherein light impinges upon end surfaces of the pin-photodiodes, the end surfaces being substantially perpendicular to the second conductivity-type of electrode of the pin-photodiodes.
