アデレード大学（オーストラリア）より講師を迎え、テラヘルツ技術に関する講演会を開催いたします。
本講演では、偏波分割多重化（PDM）に対応するための広帯域偏波フィルタや偏波状態間の変換などについてご講演いただきます。
皆様お誘い合わせの上、ぜひご参加ください。

A lecture event will be have organized on terahertz technology featuring a guest speaker from the University of Adelaide as below.
The lecture will cover topics such as wideband polarization filters for polarization-division multiplexing (PDM) and polarization state conversion, which we believe will be of great interest. All are welcome.

Enabling Polarization and Frequency Control in Silicon-Based Terahertz Integration

Terahertz frequencies offer wide bandwidths for high-speed communications and opportunities for advanced sensing. Realising these capabilities in practical systems requires compact components for polarization management and frequency-channel selection.
This seminar presents terahertz components developed for silicon-based substrate-less platform. To support polarization-division multiplexing, the work explores a broadband polarization filter that preserves the desired polarization while rejecting the orthogonal state, and an inverse-designed rotator for converting between polarization states.
To support channel selection and reduce out-of-band interference, all-silicon and hybrid silicon-metal bandpass filters have also been developed. Adjustable parallel plates in the hybrid filter allow its passband to be tuned for flexible frequency allocation.
Communication experiments, including a 4K video transmission demonstration, evaluate the components in a system context.
