摘要：

Broad-range wavelength tuning is demonstrated in tunable DBR lasers with a newly proposed super structure grating (SSG). The super structure grating is fabricated by electron beam exposure lithography. The grating performance is measured by transmittance characteristics of the super structure grating reflector. A maximum tuning range of 63 nm is obtained under CW condition while keeping single longitudinal mode. In a 50-nm tuning range, the threshold current variation is as low as 5.0-9.5 mA.
