Abstract :
High-performance devices have been developed in the 1.5-μm wavelength range by transversely integrating the lasing and tuning functions, enabling continuous wavelength tuning over a frequency range up to 900 GHz. The convenient wavelength tuning by a single control current in a tunable twin-guide (TTG) distributed-feedback (DFB) structure makes these lasers very attractive for application in coherent detection, and initial system demonstrators have already proved their suitability in practice
