1.3微米InP/InGaAsP多层限制掩埋新月型激光器
InP/InGaAsP Multi-Blocking Layer Buried Crescent Laser Emitting at1.3μm with Low Threshold Current
【摘要】 我们采用二次液相外延技术研制出1.3微米低阈值、稳定基横模激射多层限制掩埋新月型InP/InGaAsP激光器.典型室温连续工作阈值电流20mA,最低值10mA.在3-5倍阈值工作电流下仍可以稳定的基横模激射.单面微分量子效率为20-30%.
【Abstract】 1.3μm InP/InGaAsP multi-blocking layer buried crescent lasers have been fabricated bytwo step LPE growth processes.The typical and the minimum CW threshold currents are20 mA and 10 mA, respectively.Stable fundamental transverse mode operation has been ob-tained at three to five times of the threshold current.The differential quantum efficency perfacet is about 20--30%.
