应变多量子阱DFB激光器有源区的优化设计(英文)
摘要
The well number and the cavity length of 1.55μm wavelength In 1-x-y Ga y Al x As MQW DFB lasers are optimized using a simple model.A low threshold,maximum operating temperature of 550～560K,and high relaxation oscillation frequency of over 30GHz MQW DFB laser is presented.
利用一个简单模型对 1.5 5μm波长 In1 - x - y Gay Alx As MQW DFB激光器的阱数和腔长进行了优化 ,模拟得到了最高工作温度达 5 5 0～ 5 6 0 K,张弛振荡频率在 30 GHz以上的低阈值 MQW DFB.
