Abstract :
Wide range wavelength tuning by controlling the Bragg wavelength electrically was demonstrated for the first time in a newly developed 1.3 ¿m distributed Bragg reflector double channel planar buried heterostructure laser diode (DBR-DC-PBH LD). Lasing wavelength was tuned over 40 Å with 60 mA tuning current change, maintaining single longitudinal mode (SLM).
