Wide range wavelength tuning in 1.3 μm DBR-DC-PBH-LDs by current injection into the DBR region

Abstract
Wide range wavelength tuning by controlling the Bragg wavelength electrically was demonstrated for the first time in a newly developed 1.3 μm 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).
