The dependence of the photoluminescence (PL) emission wavelength of SiGe islands embedded into a Si matrix on their Ge concentration and gradient was investigated. Intense PL signals at wavelengths that can be shifted over most of the telecom wavelength range (1.38–1.77 mm) by varying the Ge concentration were observed. Using the structural island(More)
