Avalanche photodiode structures are proposed which theoretically exhibit very low excess noise. In these designs, the hole and electron ionization probabilities are made very close to unity for a single pass of the multiplication region. This is accomplished by ballistic injection across the gain region. The structures are less complex than other proposed low noise avalanche photodiode structures.
