摘　　要：利用高阶Bragg光栅成功制备出Ga Sb基DBR激光器,避免了复杂的制备工艺.利用标准接触曝光制备出16阶和24阶Bragg光栅以及双沟脊条波导结构. 16阶Bragg光栅器件在室温下实现了SMSR高达17. 5 dB的单模激光输出. CW状态下室温最大单模输出功率超过10 mW.随着注入电流变化,器件表现出出色的波长稳定性.在整个注入电流范围内,器件都保持单横模工作状态. 24阶Bragg光栅器件室温SMSR为22. 5 dB.器件的激射波长都在2. 0μm左右.GaSb-based DBR lasers with high-order Bragg gratings are fabricated without complex process.The 16^th-order and 24^th-order Bragg gratings are fabricated with double-trench ridge waveguide by using standard contact optical lithography respectively.The 16^th-order Bragg grating laser achieves single longitudinal mode continuous-wave(CW)operation at room temperature with side mode suppression ratio(SMSR)as high as 17.5dB.The maximum single mode continuous-wave output power is more than 10 mW at room temperature.The laser shows a very excellent wavelength stability against injection current.The single spatial mode operation is maintained in the entire injection current range.The 24^th-order Bragg grating laser even shows a side mode suppression ratio up to 22.5dB at room temperature.The emission wavelength is around 2.0μm.
