PHOTONICALLY ENABLED THZ COMMUNICATION LINKS

We present continuous-wave terahertz communication systems based on the optical heterodyne generation (photomixing) technique. The uni-travelling carrier photodiode is identified as a key component for conversion of optical to terahertz power. We discuss the potential for the overall system to transmit data at rates above 10 Gb/s and the limitations within the system. Finally we discuss the demonstration of photonic integrated chips for the emitter.
