AGE COMPENSATION IN OPTOELECTRONIC MODULES WITH INTEGRATED TEMPERATURE CONTROL

摘要

A method for compensating for wavelength drift in a fiber-optic laser transmitter includes; controlling a temperature within the optoelectronic (100) assembly at a defined level; driving the optoelectronic (100) assembly to emit light, wherein the emitted light has a wavelength that is within a channel of operation, the channel of operation including a range of wavelengths centered around a channel center wavelength; assessing from memory (300) within the optoelectronic (100) assembly a control value associated with the temperature of the optoelectronic (100) assembly at defined points within an operational lifetime of the optoelectronic (100) assembly; and recalculating the defined level by reference to the control value, whereby a wavelength of the optoelectronic (100) assembly is maintained within the channel of operation despite an expected drift of wavelength.
