Abstract
GaAlAs light-emitting diodes fabricated by a metalorganic chemical vapour deposition method exhibit high-power and high-speed response characteristics at least as good as those made by liquid phase epitaxial growth. Maximum external quantum efficiency, standard graded index fibre input power and cutoff frequency at a forward current of 100 mA are 3.9%, 163 ¿W and 73 MHz. respectively.
