Fano resonance lineshapes in a waveguide-microring structure enabled by an air-hole [PDF]
APL Photonics, 2019 We propose and demonstrate, by simply inserting an air-hole in the waveguide side-coupling with a microring resonator (MRR), the transmission spectrum presents Fano lineshapes at all of the resonant modes.

Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces
Advanced Photonics Research, EarlyView.Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.

Intelligent Stain‐Free Histology on Structural Colorimetric Nanocavities
Advanced Science, EarlyView.Chen and Gan et al. introduce a label‐free imaging platform using inexpensive Nanocavity‐on‐Silicon (NOS) slides. These slides transform subtle tissue variations into vivid structural colors, enabling high‐contrast histological imaging under a regular optical microscope. This stain‐free approach reveals morphological details comparable to traditional H&

Coherence of magnetic resonators in a metamaterial
AIP Advances, 2013 The coherence of periodic magnetic resonators (MRs) under oblique incidence is studied using simulations. The correlated phase of interaction including both the retardation effect and relative phase difference between two MRs is defined, and it plays a ...

, 2013 Fano resonance appears for conduction through an electron waveguide containing donor impurities. In this work, we consider the thin-film conducting chiral helimagnet (CCH) as the donor impurity in a one-dimensional waveguide model. Due to the spin spiral

An actively controlled silicon ring resonator with a fully tunable Fano resonance
APL Photonics, 2017 We demonstrate a novel way to generate Fano resonance with tunable wavelength, extinction ratio, and slope rate. The device is a silicon add-drop microring with two integrated tunable reflectors inside, which form an embedded Fabry-Perot cavity.
