Claim:
1. A method for controlling an output power of an optical transmitter, comprising: measuring an output power value of the optical transmitter at 25° C.; measuring the output power value of the optical transmitter at N additional individual temperatures to obtain N tracking error values (TE values) corresponding to said N additional individual temperature values, where N is an integer that is equal to or greater than 1; creating a lookup table covering an operating temperature range of the optical transmitter including said N individual temperature values based on one-to-one mapping between said TE values and said N additional individual temperature values; and after creating said lookup table and when said optical transmitter is in operation, reporting at an electrical digital diagnostic and/or monitoring interface of said optical transmitter an operating temperature of said optical transmitter, a corresponding one of said TE values from said lookup table, and an optical output power of said optical transmitter.
