Tuning ranges for 1.5 μm wavelength tunable DBR lasers

Abstract
Tuning ranges for 1.5 μm wavelength tunable distributed Bragg reflector (DBR) lasers were studied experimentally. Over 10.0 nm (1.25 THz) quasicontinuous tuning under 5 mW light output conditions and 4.4 nm (550 GHz) continuous tuning at 1 mW were achieved.
