Abstract :
Based on a novel large-signal dynamic analysis, external optical feedback resistant single-mode LD´s were designed and realized. Under -14 dB external optical feedback, isolator-free 2.5-Gb/s 45-km transmission was demonstrated over a wide temperature range from -40/spl deg/C to +80/spl deg/C for the first time.
