Abstract
The generation of cw Terahertz radiation from photomixing in low-temperature grown GaAs is limited by the thermal load for single emitters. We propose a new heat sinking scheme based on high thermal conductivity, transparent crystalline heat spreaders as diamond in direct contact with the active zone. A first working device based on recessed electrodes is demonstrated and has a significant power dissipation capability of more than 0.75W (average). The electrical and terahertz characteristics are analyzed.
