Laser trim and compensation methodology for passively aligning optical transmitter










Image Number 4 for United States Patent #7433375.

A method embodiment of the invention includes a scheme for trimming and compensation of a laser emitter in a fiber optic link. A laser emitter is provided. Also a reference optical power value is determined using data models of laser emitter performance generated by statistical analysis of sample population of lasers that are similar to the subject laser emitter. The performance of the subject laser is measured and qualified optical power levels for the subject laser emitter are determined using the reference operating power value and measured performance of the subject laser emitter. The driving current of the subject laser emitter is adjusted to compensate for changes in temperature until the optical power of the subject laser emitter obtains a desired qualified optical power level. Related methods of determining qualified optical power levels for a laser emitter in a fiber optic link are also disclosed. As are methods of determining a reference optical power value for a laser emitter to be coupled in a fiber optic link. Fiber optic links capable of trimming and compensation in open and closed loop configurations are also disclosed.
