Abstract
A new type of high-radiance GaAs-GaAlAs heterostructure light-emitting diode (l.e.d.) with confinement of the light-emitting area by contact resistance is described. Single heterostructure l.e.d.s of this type with active-region doping of p = 3 × 1018 cm−3 exhibit external quantum efficiency of 1% and a 3 dB modulation cutoff frequency of 66 MHz. Second-harmonic distortion was measured at below 40 dB at a 30 mA peak-peak modulation current and 50 mA direct current (= 7·0 kA/cm2).
