Paper Abstract

Terahertz (THz) imaging has progressed tremendously due the continuous development of new THz emitters and detectors. However, highly integrated array devices are desired for fast THz imaging. Advanced features such as beam steering and phase contrast imaging may be realized using more complex systems that require tight integration. Silicon photonics is an enabler for CW THz applications such as imaging and high-speed communication because of low cost and high level of integration. We present results of our research on continuous-wave THz generation using antennacoupled silicon-germanium photodiodes. THz emission up to 2.2 THz has been demonstrated.
