The requirement for increased data transmission rates for new wireless systems such as 5G and above places heavy pressure on currently allocated wireless spectrum. THz over fibre offers a technology with the potential to meet future needs for short range high data rate communications.
A single-transmitter/single-receiver THz link (0.3-0.5 THz) with a record net data rate of 260 Gbit/s is experimentally demonstrated. Spectrally efficient multi-channel signal transmission is enabled by a novel frequency-band-allocation scheme with pre-and-post-digital equalization.
We experimentally demonstrate an integrated optical millimeter-wave signal generator based on a silicon ring modulator. A 20 GHz microwave signal with 17 dB suppression ratio is obtained with a 10 GHz input signal.
We experimentally study the noise induced from thermal bistability and the intracavity dynamics of a 1550 nm stimulated Brillouin scattering laser generated from a microresonator.
