Chip Based THz Emitter for Ultra-high Speed THz Wireless Communication

Abstract

By using a monolithically integrated dualdistributed feedback (DFB) laser chip attached to a photomixing uni-travelling carrier photodiode (UTC-PD) with a THz antenna, single-channel THz photonic-wireless transmission system with a net rate of 131 Gbit/s over a wireless distance of 10.7 m has been achieved.

16-QAM Vector Terahertz-Wave Signal Generation by Simple MZM-Based Optical Frequency Comb

“…Now employing optical heterodyne beating of two independent free running lasers is the major method to produce photonic vector THz-wave signal, which has huge merits of simplifying transmitter structure design and get radio frequency carrier tuned and frequency assignment easily [18][19][20][21][22][23][24][25][26]. However, the generated continuous light-waves based on two independent running lasers encounter frequency instabilities.…”
