Abstract
The preparation and performance of 1.06 μm gallium–indium-arsenide high-radiance light-emitting diodes is described. Radiances of 15 W/steradian/cm2 at 100 mA drive were obtained. Direct modulation by means of the current drive up to 250 MHz is reported with 3 dB modulation bandwidth at 150 MHz. These sources will permit the development of wide-bandwidth fibre-optic communication systems, which can take advantage of the low fibre attenuation and material dispersion at 1.06 μm.Keywords
