Embodiment Construction
[0024] In order to more conveniently adjust the carrier transit time and the device capacitance of the avalanche photodetector (APD) and improve the high-frequency characteristics of the device, according to an aspect of the present invention, the APD in its longitudinal direction includes the original absorption layer, charge In addition to the layer and the multiplication layer, a transition layer is added, and the transition layer and the absorption layer are respectively located on both sides of the multiplication layer.
[0025] When the multiplication layer generates a large number of avalanche carrier pairs (electron-hole pairs) due to the avalanche effect, one type of carriers (such as holes) drifts longitudinally through the absorption layer to one end of the APD (from the multiplication layer the side with the absorber layer), another type of carriers (such as electrons) drift longitudinally through the transition layer (from the side with the transition layer of the ...
