Laser nanofabrication inside silicon with spatial beam modulation and anisotropic seeding

open access: yesNature Communications
Nanofabrication in silicon, arguably the most important material for modern technology, has been limited exclusively to its surface. Existing lithography methods cannot penetrate the wafer surface without altering it, whereas emerging laser-based ...

Compact Polarization Rotator Based on Surface Plasmon Polariton With Low Insertion Loss

open access: yesIEEE Photonics Journal, 2012
An ultracompact mode-evolution-based polarization rotator is proposed. The polarization rotator consists of silicon wire waveguide covered by silica buffer layer and linearly tapered thin aluminum.

Multi‐Objective Inverse Design of a Dual‐Narrowband Thermal Emitter for Optical Gas Sensing

open access: yesNanophotonics, Volume 15, Issue 18, 25 September 2026.
A lithography‐free, wafer‐scale dual‐narrowband thermal emitter is developed using a multi‐objective inverse design framework. It comprises an aperiodic Si/SiO2 dielectric multilayer deposited on a TiN refractory conductive ceramic film. Its dual emission peaks match characteristic absorption bands of CH4 and NO2 and enhance responses to both gases ...

Tailoring the Structure of Multilayered Hybrid Silicon Vertical Waveguide to Achieve Anomalous Dispersion

open access: yesIEEE Photonics Journal, 2017
In order to decrease the dispersion of the silicon vertical slot waveguide, we propose a multilayered hybrid silicon vertical waveguide structure. This multilayered waveguide is formed by three low-refractive-index regions interleaved with two narrow ...

Surrogate Scattering Matrix‐Guided Inverse Design of Nanophotonic Neural Networks

open access: yesNanophotonics, Volume 15, Issue 18, 25 September 2026.
Surrogate‐guided inverse design separates task learning from electromagnetic realization by transferring a trained passive operator to a fabrication‐aware nanophotonic structure. The electromagnetic cost of each update depends on port count rather than the dataset size.

Designing High-Performance, Power-Efficient NoCs With Embedded Silicon-in-Silica Nanophotonics

open access: yes, 2015
On-chip electrical links exhibit large energy-to-bandwidth costs, whereas on-chip nanophotonics, which attain high throughput, yet energy-efficient communication, have emerged as an alternative interconnect in multicore chips.

High Extinction Ratio and Broadband Silicon TE-Pass Polarizer Using Subwavelength Grating Index Engineering

open access: yesIEEE Photonics Journal, 2015
We propose and experimentally demonstrate a novel approach to implement a low-loss, broadband, and compact transverse electric (TE)-pass polarizer on a silicon-on-insulator platform.

Bend Waveguides on Silicon Nanowire Optical Waveguide (SNOW)

open access: yesIEEE Photonics Journal, 2011
In a previous work, we reported a novel optical waveguide named silicon nanowire optical waveguide (SNOW), which consists of arrayed silicon nanowires acting like an effective-index medium.

Inverse‐Designed Nanophotonic Structures for On‐Chip Excitation and Broadband Emission Extraction in Diamond Quantum Spin Sensing

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
Inverse‐designed nanophotonic structures on a foundry‐compatible silicon nitride chip enable efficient in‐plane green excitation and broadband red emission extraction from diamond nitrogen‐vacancy centers. A compact emitter triples the guided optical power, while a directional coupler routes ∼80% of the fluorescence to detection, advancing miniaturized

Diamond nanophotonics [PDF]

open access: yes, 2014
© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. The burgeoning field of nanophotonics has grown to be a major research area, primarily because of the ability to control and manipulate single quantum systems (emitters) and single photons on demand. For
