Control techniques for photodetector systems

A method for controlling a photodetector, the method comprising:

• receiving, by a system comprising memory and one or more processors, a target value;
• receiving, by the system, an output from the photodetector;
• generating, by the system and based at least on the target value, a bias signal;
• and
• applying, by the system, the bias signal to the photodetector to drive a parameter of the photodetector to the target value.

One or more non-transitory computer-readable media storing executable instructions that, when executed by one or more processors, cause a system to:

• receive a target value;
• receive an output from a photodetector;
• generate, based at least on the target value, a bias signal;
• and
• apply the bias signal to the photodetector to drive a parameter of the photodetector to the target value.

A system for controlling a plurality of photodetectors, the system comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the system to:
• receive a matrix of target coefficients;
• receive a plurality of outputs, each from a photodetector of the plurality of photodetectors;
• generate, based at least on the matrix of target coefficients and the plurality of outputs, a plurality of bias signals;
• and
• apply each of the plurality of bias signals to a corresponding photodetector of the plurality of photodetectors to drive a parameter of the corresponding photodetector to a target value.

A system for controlling a plurality of photodetectors, the system comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the system to:
• receive a vector of target coefficients;
• receive a plurality of outputs, each from a photodetector of the plurality of photodetectors;
• generate, based at least on the vector of target coefficients and the plurality of outputs, a bias signal;
• and
• apply the bias signal to each of the plurality of photodetectors to drive a parameter of each of the plurality of photodetectors to a target value.
