IMPACT IONIZATION DEVICES UNDER DYNAMIC ELECTRIC FIELDS
Apparatus, systems, and methods relate to use of a time-varying bias for application to an avalanche photodiode. Embodiments include systems and methods of determining an appropriate time-varying bias for application to an avalanche photodiode in linear mode. Avalanche photodiode having appropriate parameters may also be determined. Additional apparatus, systems, and methods are disclosed.
1 . A method comprising:
receiving an optical pulse at an avalanche photodiode in linear mode or equivalent below-breakdown mode;
varying a reverse bias applied to the avalanche photodiode during the reception of the optical pulse at the avalanche photodiode; and
outputting from the avalanche photodiode an electrical signal that corresponds to the received optical pulse.
