Topologically controlled multiskyrmions in photonic gradient-index lenses
Yijie Shen, Chao He, Zipei Song +8
Skyrmions are topologically protected quasiparticles, originally studied in condensed-matter systems and recently in photonics, with great potential in ultra-high-capacity informat…
Surface modulation of metal-organic frameworks for on-demand photochromism in the solid state
Samraj Mollick, Yang Zhang, Waqas Kamal +7
Organic photoswitchable molecules have struggled in solid state form to fulfill their remarkable potential, in terms of photoswitching performance and long-term stability when comp…
Nano-Trap Engineering in MOF Microenvironment for Ultratrace Iodine Sensors
Arun S. Babal, Samraj Mollick, Waqas Kamal +4
Ultra-sensitive and highly selective iodine gas sensors play a crucial role during the nuclear radiation leak for a timely detection and mitigation of pollution, ensuring the safet…
Single-mode sapphire fiber Bragg grating
Mohan Wang, Patrick S. Salter, Frank P. Payne +4
We present here the inscription of single-mode waveguides with Bragg gratings in sapphire. The waveguide Bragg gratings have a novel multi-layer depressed cladding design in the 15…
Spontaneous emission from radiative chiral nematic liquid crystals at the photonic band gap edge: an investigation into the role of the density of photon states near resonance
Th. K. Mavrogordatos, S. M. Morris, S. M. Wood +2
In this article, we investigate the spontaneous emission properties of radiating molecules embedded in a chiral nematic liquid crystal, under the assumption that the electronic tra…
Active metamaterials with negative static electric susceptibility
F. Castles, J. A. J. Fells, D. Isakov +3
Well-established textbook arguments suggest that static electric susceptibility must be positive in "all bodies" [1]. However, it has been pointed out that media that are not in th…
