Design and growth of III-V semiconductors is the core service of Twenty-One Semiconductors. We are specialized in fabrication of light-emitting structures and saturable absorbers covering the whole range from orange to near-infrared. These wavelengths between 600 and 1100 nm are reached by using the material systems AlGaInP and InAlGaAs on gallium arsenide substrates. To perfectly match your needs, we can fabricate on wafers with up to 4-inch sizes.
