Patent ID: 7321606

Claim:
A method of establishing a trim and compensation scheme for a laser emitter in a fiber optic link where the laser emitter is selected from among a group of similar lasers, the method comprising: a) providing data models that characterize laser performance for a group of lasers, the models being generated using laser performance data obtained from measurements of laser properties taken from a sample group of lasers taken from the group of lasers; b) determining a base power level using information from the data models and a predetermined set of user specified performance parameters; c) determining whether the base power level satisfies a set of pre-specified operating parameters; if a laser having the determined base power level does not satisfy the set of pre-specified operating parameters, the user specified performance parameters are adjusted and the operations of b) and c) are repeated to determine a new base power level; if a laser having the determined base power level does satisfy the set of pre-specified operating parameters, then process moves on to the next operation d); and d) determining a relationship between temperature and associated current values that can be used to regulate laser performance over a range of temperature.
