THz photonics-based transmitter using multicore fiber combined with UTC-PD array for high data transmission in 300 GHz band

This work aims at illuminating an UTC-PD array with a multicore fiber towards multiple THz carrier generation. This photonics-based transmitter is expected to increase either the data rate via spatial multiplexing on different carriers or the emitted THz-power and therefore the transmission reach of THz systems operating in 300 GHz band. Preliminary results of the characterization of the sub-systems of the transmitter that is under development are presented here.
