In(As, P)/InP strained multiple quantum wells (SMQW's) were grown withgas-source molecular-beam epitaxy (GSMBE). A successful control of the Ascomposition was achieved over a wide range by using two techniques.High-quality samples were characterized structurally and optically by x-raydiffractometry, transmission electron microscopy (TEM), photoluminescence(PL) and absorption measurements. Excitonic emission energy and the criticallayer thickness of In(As, P)/InP SMQW's are calculated as a function of theAs composition. The results show that 1.06, 1.3 and 1.55 μm excitonicemission can be achieved at room temperature using this material system. Wealso discuss the perspective of using In(As, P)/InP SMQW's for modulatorapplication.
