| Abstract: | The structure and the performance of a cascaded avalanche photodiode (APD) based on cascaded home-junctions are discussed. Similar to the hetero-structure superlattice APD, such a device has a lower excess noise and a higher gain at lower bias voltages than conventional APDs. In addition to the ionization ratio, several parameters also affect the device's performance. |
