摘要
超辐射发光二极管因具有短的相干度、较宽的光谱、高的输出功率及工作稳定性好的特性,广泛应用于各种工程领域。从量子阱结构出发,在详细分析了量子限制效应的基础上,设计了一种量子阱脊波导结构,并从功率分布角度定义了限制因子,对脊波导的脊高、脊宽、包层厚度等参数进行了结构优化,经过数值模拟及结果讨论,确定了脊宽为2μm、脊高为0.5μm、包层厚度为0.2μm的脊波导结构设计对光密度分布起到了良好的限制作用。
Super luminescent Diode for short coherent length,wide spectrum,and high output power and so on,is widely used in various engineering fields.In this paper,the quantum well structure and the quantum confinement effect are analyzed,and a quantum well ridge waveguide structure is designed.The limiting factor is defined from the angle of power distribution.Height and width of ridge waveguide,thickness of the cladding and other parameters are optimized.Through the numerical simulation and results discussion,the ridge waveguide structure design for ridge width of 2 μm,ridge height of 0.5 μm and the cladding thickness of 0.2 μm is confirmed to limit the effect on optical density distribution.
