【Abstract】 1.3 μm InGaAsP/InP double-channal planar buried heterostructure lasers have been fabricated with supper-cooling growth technique by a two step LPE growth pro-cess.Minimum threshold current of the lasers at room temperature is 15mA and thetypical value is 20mA.The highest CW operation temperature is 80℃ and the out-put pQwer is 2mW.The output stable single longitudinal mode is obtained at four ti-mes of threshould current.更多还原
