Optical communication systems form the backbone of modern high-capacity networks, leveraging light propagation in fibres to transmit data over vast distances with minimal loss. Central to their ...

Terahertz frequency band (0.1 ~ 10 THz) can provide ultra-high transmitting rates for massive emerging applications. However, due to the radio frequency impairments and limited signal processing ...

Additionally, these waves hold great promise for wireless communication. Advances in THz nonlinear optics, which can be used to change the frequency of electromagnetic waves, are essential for the ...

A research team led by The Chinese University of Hong Kong (CUHK) has developed a novel integrated all-optical signal ...

Jean-Michel Ménard, Associate Professor of Physics at the University of Ottawa and a team of researchers have paved the way for developing devices capable of upconverting electromagnetic signals to ...
