Abstract
A monolithic Optoelectronic Integrated Circuit including a photodiode and a CMOS readout circuit is described in which the diode is formed by compositionally graded layers of In.sub.x Ga.sub.1-x As selectively epitaxially grown between a substrate of Si and an absorption layer of In.sub.x Ga.sub.1-x As, the areas of said layers being less than 500 .mu.m.sup.2 and wherein a readout circuit on said substrate is coupled to said diode.
