  1. Avalanche photo diodes (APDs) internally multiply the primary signal photocurrent before it enters the input circuitry of the following amplifier which increases receiver sensitivity.

  2. For carrier multiplication to take place, the photo carriers generated must traverse a region where a very high electric field is present. This carrier multiplication mechanism …
