Laser &Photonics Reviews, EarlyView.Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...

Huygens metasurface supporting quasi-bound states in the continuum for terahertz gas sensing
Scientific ReportsWe investigate a terahertz (THz) gas sensing platform based on all-dielectric metasurfaces that support quasi-bound states in the continuum (quasi-BIC) with both electric and magnetic dipole resonances.

Spontaneous Parametric Down‐Conversion in 4H‐SiC Integrated Platform
Laser &Photonics Reviews, EarlyView.Photon‐pair generation in 4H‐SiC‐on‐insulator integrated platform is demonstrated through spontaneous parametric down conversion. Different second‐order nonlinear interactions are also shown in 4H‐SiC waveguides, highlighting the potential to exploit diverse phase‐matching mechanisms on this platform.
