Abstract
It is shown that strained-layer InGaAs quantum dots grown on GaAs substrates can extend the operating wavelength of GaAs-based optoelectronic devices to wavelengths near 1.3 μm. Specifically a 1.27 μm resonant-cavity photodiode with a quantum dot absorbing region is demonstrated. This photodiode exhibits a peak external quantum efficiency of 49% with a spectral bandwidth of 1.2 nm
