| Abstract: | The performances of high speed and high radiance GaAs/GaAlAs DH LEDs used for Fiber optical communications are described.Their electrical bandwidth is higher than 60MHz and optical bandwidth is over 100MHz. The source radiance was measured to be 1017W/cm2·sr at 200mA. The output power at the pigtail of a fiber is more than 160μW with a draving current of 200mA (core diameter of fibers= 60μm and numerical aperture NA=0.2). We have analysed and discussed the factors affecting on both radiative output and the modulation capability, andthe trade-off was reasonably selected. |
