Abstract
The use of Distributed FeedBack lasers for Passive Optical Networks requires specific architecture and appropriate algorithms for fine tuning and spectrum management. These algorithms can be implemented over simple single-mode lasers using thermal closed-loop with a control structure and 2x2 pre-equalization stage; the wavelength and optical power are tuned precisely with negligible oscillations for channels spaced 6.25 GHz under an ultra-dense-wavelength-division-multiplexing scenario.
