Active Formation of Friedrich–Wintgen Bound States in the Continuum in a Hybrid Plasmonic–Photonic Structure

open access: yesAdvanced Photonics Research, EarlyView.
A method is proposed for actively generating Friedrich–Wintgen bound state in the continuum (FW BIC) in a hybrid plasmonic–photonic structure near the commercially important communication wavelength. In addition, interactions between dark and bright modes can further form the FW BIC and support electromagnetically induced transparency‐like with maximum

Purinylidene‐Based Iridium(III) Phosphors for Efficient Purple Phosphorescence and Organic Light‐Emitting Devices

open access: yesAdvanced Photonics Research, EarlyView.
A family of purinylidene based Ir(III) emitters, namely, f‐ct2a–d, are synthesized and utilized as both dopants and sensitizers in the construction of efficient purple to deep‐blue organic light‐emitting diode devices. It is very challenging to achieve highly efficient and low roll‐off purple to deep‐blue organic light‐emitting diodes (OLEDs) due to ...

Tailoring Second Harmonic Generation via Strong Coupling in a One‐Dimensional Photonic Crystal Heterostructure

open access: yesAdvanced Photonics Research, EarlyView.
The strong coupling is investigated as an effective method to modulate the second‐harmonic generation (SHG) in the defect mode and Tamm plasmon resonances. Throughout the entire anticrossing Rabi splitting process induced by strong coupling, the difference in SHG efficiency between two resonances can be modulated by up to two orders of magnitude ...

Dynamic Humidity Modulation of Quasi‐Bound States in the Continuum by Symmetry Breaking in Geometry and Permittivity

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a humidity‐modulated strategy to regulate the dynamic transition from quasi‐BICs to BICs based on the symmetry‐breaking in geometry and permittivity for the hybrid photonic‐plasmonic asymmetric gratings. It proves that it is a promising approach for dynamic regulating optical properties and applied in fabricating various micro ...

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens

open access: yesAdvanced Photonics Research, EarlyView.
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...
