Optimal Design of Arrayed Waveguide Grating

Journal of the Optical Society of Korea, 2004
This paper describes the optimal design of an AWG spectrum to meet various specifications and improve some physical parameters. The objective function is the norm of the difference between design parameters and target values. To obtain the design parameters, the Fourier model is employed and the design variables arc spacing of array waveguide, width of

Giant Enhancement of the Anomalous Transverse Magneto‐Optical Kerr Effect in a Magneto‐Optical Grating

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
We demonstrate an indirect magneto‐optical coupling mechanism that overrides the symmetry‐induced suppression of s‐polarized TMOKE. A quasi‐two‐dimensional grating coordinates orthogonal resonances to establish a near‐zero reflection background and maximal near‐field asymmetry, achieving a theoretical‐limit TMOKE of ∼2.

Waveguide‐Based Four‐Channel Crosstalk‐Free Metahologram Multiplexed by Diffraction Orders

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A diffraction‐order‐multiplexed, four‐channel metahologram integrates a flat glass waveguide and an array of titanium dioxide nanopillars to realize crosstalk‐free holographic projection. Light undergoes total internal reflection within the waveguide and gets out‐coupled by diffraction from the nanopillar array.

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Quantum electrodynamics accurately describes all known forms of modern optics and photonics regarding interactions between photons and matter. In this context, bound states in the continuum with photon confinement in momentum space are envisioned to open an exciting branch called reciprocal quantum electrodynamics. It complements the cavity counterpart

Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

A Long‐Period Grating Formed by Residual Stress on Thin‐Film Lithium Niobate With Efficient Electro‐Optic and Thermo‐Optic Tuning

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Three‐dimensional schematic (a) of the proposed long‐period grating (LPG) on thin‐film lithium niobate (TFLN) and its cross‐sectional view (b) showing a TFLN core with a BCB cladding and a periodic metal structure. Residual stress generated at the metal–BCB interface creates the LPG.

Pixelated Laser with Tailored Emission Spectrum Photopatterned by Digital Holographic Microscopy

Advanced Optical Materials, Volume 14, Issue 17, 8 May 2026.
Azobenzene‐based surface‐relief gratings inscribed via DHM‐integrated holographic lithography enable programmable pixelated DFB laser architectures. This approach allows independent control of grating parameters across a 2D array, enabling spatially tailored emission spectra.

Design of an arrayed waveguide grating with flat spectral response

SPIE Proceedings, 2002
Arrayed Waveguide Gratings (AWGs) are key components in current and future optical network realizations. In order to prevent the need of accurate wavelength control the transfer function of the AWG should ideally have a rectangular shape. Several techniques have been proposed in order to flatten the Gaussian-like transfer function of the conventional
