Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

open access: yesAdvanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...
