摘要
提出了一种提高超发光二极管(SLDs)发射光谱宽度的方法。介绍了采用串联有源层结构的1.3 μ m InGaAsP/InP sld的制备方法。对于该器件,光谱宽度加宽超过100 nm,实现了9.2 μ m的短相干长度,是传统1.3 μ m sld的四分之一。
A very wide spectrum superluminescent diode at 1.3 mu m
An approach that broadens the emission spectral width of superluminescent diodes (SLDs) is proposed. The fabrication of 1.3- mu m InGaAsP/InP SLDs incorporating a structure of tandem active layers is described. For this device, the spectral width is broadened over 100 nm, achieving a short coherence length of 9.2 mu m, one-fourth that of conventional 1.3- mu m SLDs.<>
