Abstract
An avalanche photodiode having a reduced capacitance is provided. The avalanche photodiode includes a wide band gap layer in its depletion region. The width of the wide band gap layer increases the extent of the depletion region, thereby reducing the capacitance while minimizing the impact on the dark current.
