“…One of the promising application areas of sub-terahertz and terahertz technologies is telecommunication systems [1,2]. In particular, the leading scientific and technical schools in the world are creating the sub-terahertz and terahertz band devices with fundamentally new dimensions, noise immunity and energy efficiency for 4G/LTE and 5G mobile communication networks, high-speed transmission of high and ultra-high definition video signals, radio relay systems for direct visibility and radars and sensors to obtain more accurate and detailed operational information about the state of the controlled object or terrain.…”

Abstract-We experimentally demonstrate, for the first time, the photonic generation of a continuous tunable THz wireless signal based on using optical phase locked loop (OPLL) subsystem and optical frequency comb (OFC). The OPLL is employed to select one optical tone out of optical comb and shift it by desired frequency offset allowing for the frequency tuneability of THz carrier signal. The selected optical tone from OPLL is heterodyned mixed with another selected optical tone of the optical comb to generate a stabilized THz frequency carrier with a low phase noise. The proposed setup is demonstrated by transmitting wirelessly a THz signal modulated with 10 Gbaud QPSK filtered with square root raised cosine (SRRC) at 0.1 roll off factor. The system performance is evaluated for four tuned THz carrier frequencies by changing the wavelength of the laser included in the OPLL. This configuration is a promising architecture that would allow a THz carrier to be flexibly generated at the central office with high frequency stability and low phase noise.

“…A mode-locked laser diode (MLLD) can be employed for heterodyne mm-wave generation, and thanks to mode locking and correlation of phase noise between the optical lines. This source does not require any external locking scheme to partially alleviate phase noise on RF signals [7]- [9], which results in better system stability and cost efficient mm-wave generation [10]. The influence of phase noise on mm-wave and sub-THz RoF system was investigated [11]- [13].…”
