Background & Aims: Liver fibrosis is characterized by sustained injury stress, chronic inflammation, and repeated cell death and repair, all of which promote the progression of end-stage liver diseases (e.g., liver cirrhosis and carcinoma).
View Article and Find Full Text PDFA simple yet insightful question is whether it is possible to arrange optical resonances in such a way that their collective response differs from that of the individual constituents. Here, inspired by the collective oscillation of spatially localized modes and Fourier duality between real and momentum spaces, we demonstrate a chiral emission of collective guided modes by leveraging the omnidirectional hybridization of individual guided resonances within a photonic crystal slab. Specifically, we encircle a uniform photonic crystal with isotropic boundaries and hybridize discrete bulk guided resonances into a series of collective modes owing to the scatterings of the boundaries.

- Emitting light in specific directions is crucial for technologies like communication and displays, but current methods are bulky and inefficient.
- Researchers have designed a new type of directional emitter that uses a compact laser based on photonic crystals for dynamic beam steering.
- This laser allows for rapid adjustment of light direction, achieving a small beam steering range and maintaining efficiency, which could benefit various applications in automotive and robotics.
