Predictive Design to Determine Optimal Absorber Placement in Colloidal Photonic Crystals

Advanced Optical Materials, EarlyView.
The inclusion of absorbing material is known to increase color saturation in photonic crystals. Predictive design based on mathematical structure optimization is used to identify optimal designs for the absorber amount and position within a photonic colloidal crystal and experimentally realized. This strategy shows that the placement of the absorber at

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

Advanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2

Advanced Optical Materials, EarlyView.
The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...

Advancing Solar Modulation Ability of Near Infrared Thermochromic Cholesteric Liquid Crystal Smart Window Films Using a Waveplate

Advanced Optical Materials, EarlyView.
This work presents the use of a waveplate in thermochromic materials for smart windows. The waveplate enables the optical material to transition from a narrow band reflection to broad band ambidextrous reflection upon heating, resulting in a solar transmission modulation of 5.2% which is four times greater than typical thermochromic cholesteric liquid ...
