3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity

Laser &Photonics Reviews, EarlyView.
Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

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.

1 PHz of Coherent Bandwidth from a Compact Fiber Device

Laser &Photonics Reviews, EarlyView.
A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...
