Optical Poling of Ferroelectric Liquids

Advanced Optical Materials, EarlyView.
The optical control of size and shape of polar domains in ferroelectric nematic liquid crystal cells is reported. In sufficiently thin samples, light irradiation induces the formation of a novel singular spiral‐shape arrangement of the polar director as a response to localized illumination.

Nanoimprinting of Mesoporous Titania: Direct Patterning and Refractive Index Control in the Visible

Advanced Optical Materials, EarlyView.
Nanoimprinted mesoporous TiO₂ (pTiO₂) films are demonstrated as high‐resolution optical materials with tunable porosity, refractive index, and mechanical response. Sub‐micron patterning of planar optics is shown alongside a refractive index contrast Δn ≈0.7.

Non‐Reciprocal Terahertz Topological Sensor on a Silicon Chip

Advanced Optical Materials, EarlyView.
A non‐reciprocal terahertz topological sensor (NTTS) is experimentally demonstrated on a silicon valley photonic crystal chip by detecting the thickness and position changes of a polyimide membrane. The sensor exploits detuning between clockwise and counterclockwise topological cavity modes, induced by integrated magneto‐optical InSb, to achieve non ...

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

Advanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Plasmonic Nanoparticle‐on‐Nanoslit Antenna as Independently Tunable Dual‐Resonant Systems for Efficient Frequency Upconversion

Advanced Optical Materials, EarlyView.
The nanoparticle‐on‐slit (NPoS) cavity has emerged as a sub‐wavelength platform for efficient coherent frequency conversion between mid‐infrared and visible light, and for nanoscale nonlinear vibrational spectroscopy. This numerical study identifies the NPoS quasi‐normal modes, relates them to known nanogap patterns, and predicts the relative ...
