Abstract: We demonstrate a ridge waveguide sampled-grating distributed-feedback laser with quasi-continuous wavelength coverage over a 35nm range.The design is based on a 320nm-thick butt jointed passive waveguide optimized for carrier injection tuning.The butt-joint technology enable optimize the passive waveguide as well as active section.By tuning mirror sections,the laser provides 35nm tuning while maintaining >30dB sidemode suppression ratio.
Key words: SGDBR diode laser, tunable laser, butt-joint regrowth
