Abstract
A system and an apparatus used to control laser diodes in optical communications systems, wherein the targeted or desired laser power can be varied, if needed, as a function of the laser temperature, and/or any other pertinent parameters. The adjustment of the targeted laser power or of the laser modulation current, via analog signals provided by digital-to-analog converters (DAC's), may be implemented either as a table lookup or as an explicit equation of one or more variables. If implemented as an explicit equation, the curve fit used to generate the equation may be any order.
