Polarization‐division multiplexing is crucial for increasing channel capacity and spectral
efficiency in communications. A key component is the polarization multiplexer, which …

Due to the exponentially growing global mobile data of wireless communications evolving
from 5G to 6G in recent years, research activities of leveraging terahertz (THz) waves to …

Although substrateless micro-scale silicon waveguides are a useful and versatile platform
for terahertz waves, the fact that modal fields occupy the volume of the core limits the …

Terahertz (THz) devices, especially waveguide-type functional devices related to
transmission and control, are severely scarce due to the lack of effective design and …

We observe that the modal field distribution of a dielectric slot waveguide closely resembles
a magnetic dipole antenna. Such an aperture distribution traditionally demands metals …

All-silicon substrateless waveguides have become a leading contender for terahertz device
integration owing to their broad operating bandwidth and exceptional efficiency. However …

Terahertz sources require compact lenses for efficient outcoupling and manipulation of
terahertz waves. Traditional terahertz lenses are bulky and require high-precision fabrication …

All-silicon substrateless integrated systems are suitable to wide-ranging terahertz
applications due to their low-loss characteristics. A broadband, high-extinction level …
