Semiconductor Bragg mirrors on InP substrates that use GaAs/GaSb and AlAs/AlSb superlattices for the optically reflecting layers are described. The use of superlattices circumvents difficulties with growth of the GaAsSb and AlAsSb alloys, and they are transparent for wavelengths as short as 1050 nm. The mirrors can be combined with conventional InGaAsP active layers that can also be grown on InP.
