ABSTRACT:
A solid state electromagnetic wave amplifier is provided with confinement structures for the prevention of transverse carrier wave diffusion into the amplifier body. The carrier waves are confined with a non-metallic semiconductor layer sandwiched between a semi-insulating substrate and a spacer insulating layer. The amplifier can operate at frequencies up to on the order of 100 GHz.
