n +-InP growth on InGaAs by liquid phase epitaxy

Abstract
High‐quality epitaxial growth of InP over InGaAs without dissolution has been achieved by using Sn‐rich, rather than the more conventional In‐rich, solutions. This technique, which produces n+‐InP, is directly applicable to growth of pin and avalanche photodiode structures designed for operation in the 1.55‐μm wavelength region of minimum loss in optical fibers.
