200 GHz communication system using unipolar InAs THz rectifiers
Paper in proceeding, 2013
We report on the first use of a THz detector based on InAs rectifying nanochannels in a communication system. The transmitter is composed of an electronic multiplication chain, externally amplitude modulated at the input signal. The system has been driven at 200 GHz and up to 500 Mbps data signals have been transmitted in an indoor configuration. In contrast to most nanodevices, the InAs detector has a low impedance (580 ω) and is therefore easily loaded by 50 ω electronics. The data rate limitation is mainly coming from parasitics coupled in the board. © 2013 IEEE.
