title = "Full-C-Band High-speed High-reliability Wavelength Switching at Tunable DFB Laser Array with Current/Temperature Cooperative Control",
abstract = "To realize a high-speed high-reliability wavelength switching at future WDM networks, we proposed the injection-current/temperature cooperative control method of the tunable-distributed-feedback (DFB) laser array (TLA) for avoiding a large injection current, which is the primary cause of laser degradation. We successfully demonstrated a full-C-band wavelength switching within 124 ms by rapid increase of the injection current and following gradual decrease of the injection current to avoid laser aging. Compared to the conventional control method, the meantime to failure of the TLA in the proposed method is estimated to be extended by 44 times.",
