Abstract

For high-power pulse generation at 1060-nm, distributed Bragg reflector tapered lasers were investigated. The lasers consist of a tapered section, a ridge waveguide (RW) absorber section and a passive grating section with a sixth-order surface grating. For the generation of short optical pulses, the tapered section was biased with a dc-current and the RW absorber section was modulated with a 1-GHz sinusoidal current. At a repetition rate of 1 GHz-6.3 W optical pulses with 74-ps full-width at half-maximum and a small spectral widths of 50 pm were generated.
