Interferometer -based Technology for Optical Nanoscale Inspection

open access: yesMeasurement Science Review, 2014
We demonstrate the interferometer-based approach for nanoscale grating Critical Dimension (CD) measurements and prove the possibility to achieve no worse than 10 nm accuracy of measurements for 100 nm pitch gratings.

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

open access: yesNanophotonics, Volume 15, Issue 16, 26 August 2026.
The physical origins of resonance effects in one‐dimensional periodic photonic lattices are studied to assess the relative roles of Fabry–Perot, Mie, and guided‐mode resonance mechanisms. It is shown that lattice resonance is fundamentally governed by lateral leaky Bloch modes and their coupling to external radiation via guided‐mode resonance.

Conditions for Minimizing the Computational Complexity of the RCWA Calculation of the Diffraction Efficiency of Sawtooth Two-Layer Double-Relief Microstructures

open access: yesPhotonics, 2023
In this study, novel recommendations are presented and substantiated for selecting the number of modes and optical thicknesses of flat lattice slabs that make up microreliefs, which minimize the computational complexity of the rigorous coupled-wave ...

Optical Responses From Zero Optical‐Path‐Length Object

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Reciprocal Asymmetric Transmission in Directionally Metallized Silica Nanogratings With Broken Lateral Mirror Symmetry

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Directional silver coating breaks lateral mirror symmetry in a reciprocal silica nanograting. Opposite in‐plane illumination directions redistribute optical power differently among diffraction and absorption channels, producing strong polarization‐preserving lateral transmission contrast.

Field‐Programmable Mobile Magneto‐Photonic Metaparticles for Active Light Manipulation and Steering

open access: yesAdvanced Materials, Volume 38, Issue 47, 21 August 2026.
We report magneto‐photonic metaparticles that integrate magnetic actuation with nanoimprinted metagratings, enabling mobile and programmable beam steering in aqueous environments. This platform achieves real time, directional light control beyond static or line‐of‐sight systems, while remaining compatible with scalable fabrication, providing a ...

Scalable simple liquid deposition techniques for the enhancement of light absorption in thin films: Distributed Bragg reflectors coupled to 1D nanoimprinted textures

open access: yesAIP Advances, 2017
Light trapping within a light absorbing medium is a key to highly efficient thin film solar cells. We propose a large-scale procedure based on materials with low absorption for the fabrication of combined Distributed Bragg Reflector (DBR) and grating ...

A Scalable Large‐Area Fabrication Strategy for Transparent Polymeric Encapsulated Metagratings

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Transparent encapsulated polymeric guided‐mode resonant metagratings are fabricated by thermal nanoimprint lithography and experimentally validated through structural and optical characterization. The scalable fabrication strategy enables selective RGB reflection and provides a practical route toward large‐area augmented reality and wavelength ...
