Strained Layer Superlattices covering the range 1.6-2 µm

Strained-Layer Superlattices,obtained by alternate MBE growth of Inx1Ga1-x1As and Inx2Ga1-xAs on InP substrates, were grown lattice matched to InP. Such structures, which involve only ternary alloys, allow any emitting wavelength in the range 1.6 to 2µm.
