Trimming of optical response for tunable photonic devices

An optoelectronic circuit used with signal light and with constant supply power, the optoelectronic circuit comprising:

• one or more tunable photonic devices disposed on a platform and being configured to condition the signal light, each tunable photonic device fabricated with at least one optical characteristic being electronically tunable, a fabricated performance of the at least one optical characteristic for each tunable photonic device being variable at a variance from a target performance of the at least one optical characteristic due to a difference in fabrication tolerance;
• at least one ground bus and at least one power bus disposed on the platform and being configured to connect to the constant supply power;
• and
• one or more sets of electronic components disposed on the platform, each set being disposed in electrical communication with an associated one of the one or more tunable photonic devices between the at least one ground bus and the at least one power bus, the electronic components in each set being selectively configurable to tune the at least one optical characteristic of the associated tunable photonic device, each set being independently configurable to diminish the variance between the target and fabrication performances of the at least one optical characteristic for the associated tunable photonic device
• wherein each of the one or more sets of electronic components comprises a bank of the electronic components disposed in parallel on electrical traces between the at least one ground bus and the associated tunable photonic device, each of the electrical traces having a fuse, each of the fuses being selectively configurable between a conductive state and a non-conductive state.
