Engineering 2023年第11期30卷 49-54页

作者： Desong Wang Ke Wu Poly-Grames Research Center Department of Electrical EngineeringPolytechnique MontréalMontrealQC H3T 1J4Canada

Ultrashort pulse transmission has been recognized as a primary problem that fundamentally hinders the development of ultrafast electronics beyond the current nanosecond *** requires a transmission line or waveguide that exhibits an all-pass frequency behavior for the transmitted ultrashort pulse ***,this type of waveguiding structure has not yet been practically developed;groundbreaking innovations and advances in signal transmission technology are urgently required to address this ***,we present a synthesized all-pass waveguide that demonstrates record guidedwave controlling capabilities,including eigenmode reshaping,polarization rotation,loss reduction,and dispersion *** experimentally developed two waveguides for use in ultrabroad frequency ranges(direct current(DC)-to-millimeter-wave and DC-to-terahertz).Our results suggest that the waveguides can efficiently transmit picosecond electrical pulses while maintaining signal *** waveguide technology is an important breakthrough in the evolution of ultrafast electronics,providing a path towards frequency-engineered ultrashort pulses for low-loss and low-dispersion transmissions.
