Abstract
A photodetector includes a substrate, a first optical absorber, and a second optical absorber. The first optical absorber is disposed in the substrate along a direction of propagation of an optical signal through the substrate. The first optical absorber is offset in the substrate according to an offset of the optical signal in a direction orthogonal to the direction of propagation. The second optical absorber is disposed in the substrate along the direction of propagation of the optical signal. The second optical absorber is offset in the substrate according to the offset of the optical signal in the direction orthogonal to the direction of propagation.
