Abstract :
Broadband light emitting diodes with output over the entire 1.4-1.9 μm wavelength range are demonstrated. These devices employ digital pseudo-alloys, comprising InGaAs-InGaAlAs short-period superlattices, to construct quantum wells, quantum barriers and separate confinement layers with different bandgaps and strain
