In this article we report on the status of metamorphic buffers and devices on GaAs grown by MBE. We compare metamorphic devices on GaAs with lattice matched devices on InP with respect to physical and economical aspects. Pseudomorphic electrical devices and metamorphic optical devices on GaAs were combined to fabricate monolithically integrated 40 Gb/s photoreceivers. Three types of MHEMTs for low cost, mm-wave, and high bit-rate digital applications are presented.
