摘　　要：A novel unselective regrowth buried heterostructure long-wavelength superluminescent diode （SLD） with a graded composition bulk InGaAs active region is developed by metalorganic vapor phase epitaxy （MOVPE）. At a 150mA injection current, the full width at half maximum of the emission spectrum of the SLD is about 72nm, ranging from 1602 to 1674nm. The emission spectrum is smooth and flat. The ripple of the spectrum is less than 0.3dB at any wavelength from 1550 to 1700nm. An output power of 4.3mW is obtained at a 200mA injection current under continuous-wave operation at room temperature. This device is suitable for the applications of light sources for gas detectors and L-band optical fiber communications.研制了一种新型的非选择性再生长掩埋异质结构长波长超辐射二极管(SLD).该器件采用渐变组分体材料InGaAs作为有源区,由金属有机物化学气相外延制备.150mA下,SLD发射谱宽的半高全宽为72nm,覆盖范围从1602到1674nm.发射谱光滑、平坦,光谱波纹在1550到1700nm的范围内小于0.3dB.室温连续工作,注入电流200mA下,器件获得了4.3mW的出光功率.器件适用于气体探测器和Lband光纤通信的光源.
