Claim:
1. An apparatus for controlling, monitoring, and/or communicating with an optical device, photonic integrated circuit or subassembly, the apparatus comprising: an optical device including a tunable laser having two mirrors; and a field programmable device including programmable hardware gates coupled to the optical device, wherein the field programmable device is configured to act as a control device for the apparatus and to implement a plurality of functions at a gate level for controlling, monitoring, and/or communicating with the optical device, each of the plurality of functions being configured to run as a concurrent process within the field programmable device; wherein the plurality of functions includes functions to obtain one or more gain-voltage maps by tuning laser mirror currents of the tunable laser at a temperature value; and wherein the plurality of functions further includes functions to determine lasing wavelengths corresponding to minima of the one or more gain-voltage maps, the lasing wavelengths being used for tuning or calibrating the tunable laser of the optical device.
