Modulation of the absorption coefficient at 13 μm in Ge/SiGe multiple quantum well heterostructures on silicon
Demonstration of modulation of the absorption coefficient at the 1.3 um telecommunication wavelength in a Si based device. It represents a major outcome of the EPSRC UK Silicon Photonics project (EP/E065317/1) and has been followed by a further paper in J Appl. Phys. The work was enabled by epitaxial growth of multiple Ge quantum wells with monolayer control within a strained balanced SiGe heterostructure, that has been reported in 5 other journal papers and 10 conferences from the NanoSilicon group within the REF period. The work led to a further EPSRC project on Ge quantum cascade lasers (EP/H025294/1).
