A. Mircea et al., STRAINED MULTIQUANTUM-WELL HETEROSTRUCTURES FOR LASERS, MODULATORS AND INTEGRATED OPTICAL-DEVICES AT 1.3-1.55MU-M, Materials science & engineering. B, Solid-state materials for advanced technology, 28(1-3), 1994, pp. 279-284
In recent years it has become clear that the adequate inclusion of str
ain in the design of complex InGaAsP heterostructures offers wide oppo
rtunities for improving the performances of optoelectronic devices. Th
is paper discusses two different kinds of strained heterostructure dev
ices: (i) polarization-independent electroabsorption modulators and (i
i) constant y (i.e. constant As/P) lasers at 1.3 and 1.55 mu m. Finall
y, phenomena of alloy composition instability at growth time will be d
emonstrated which may cause practical limitation in the design.
