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 ...

All‐Optically Driven Optofluidic Light Modulator
Advanced Optical Materials, EarlyView.In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels
Advanced Optical Materials, EarlyView.Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces
Advanced Optical Materials, EarlyView.Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.
