Abstract
A photodetector may include a substrate having a larger lattice constant than an absorber layer. A reverse graded set of buffer layers may provide lattice matching between the substrate and the absorber layer. The substrate may comprise indium arsenide (InAs). The absorber layer may comprise one of indium gallium arsenide (InxGa1-xAs), indium arsenide phosphide (InAsxP1-x), and indium aluminum arsenide (InxAl1-xAs).
