Unveiling charge dynamics on the generation of high extinction wide pulse generation on thin-film lithium tantalate
Ayed Al Sayem, Shiekh Zia Uddin, Ting-Chen Hu +6
We experimentally demonstrate high-extinction optical pulse generation in thin-film lithium tantalate (TFLT), achieving a wide range of pulse widths with sharp rise and fall edges,…
Compositional gradient engineering for enhanced ferroelectricity in ultrathin AlScN
Zekun Hu, Haiwen Zhang, Rajeev Kumar Rai +12
Ferroelectric AlScN is promising for CMOS-compatible non-volatile memory, but thickness scaling is limited by leakage, premature breakdown, and defect-mediated failure. Here we sho…
Controlled non-volatile modulation of optical dispersion in monolayer tungsten disulfide via ferroelectric polarization patterning
Yuhong Cao, Zekun Hu, Jason Lynch +7
The manipulation of optical properties, including reflection, refraction, polarization, phase, and frequency, has long been central to advancing photonic and optoelectronic technol…
Photoinduced metastable cation disorder in metal halide double perovskites
Shunran Li, Burak Guzelturk, Conrad A. Kocoj +18
Lead-free perovskites have emerged as environmentally benign alternatives to lead-halide counterparts for optoelectronics. Among them, the double perovskite Cs2AgInCl6 family exhib…
Self-Hybridized Exciton-Polariton Photodetectors From Layered Metal-Organic Chalcogenolates
Bongjun Choi, Adam D. Alfieri, Wangleong Chen +1
Exciton-polaritons (EPs) arising from strong light-matter coupling offer new pathways for controlling optoelectronic properties. While typically requiring closed optical cavities f…
Reconfigurable, non-volatile control of optical anisotropy in ReS2 via ferroelectric gating
Mahfujur Rahaman, Seunguk Song, Aaliyah C. Khan +8
Electrically tunable linear dichroism (LD) with non-volatile properties represents a critical yet elusive feature for next-generation integrated photonic elements in practical devi…
Natural Hyperbolicity of Hexagonal Boron Nitride in the Deep Ultraviolet
Bongjun Choi, Jason Lynch, Wangleong Chen +6
Hyperbolic media enable unique optical phenomena including hyperlensing, negative refraction, enhanced photonic density of states (PDOS), and highly confined polaritons. While most…
High-Temperature-Resilient Hyperbolicity in a Mixed-Dimensional Superlattice
Jason Lynch, Tzu-Yu Peng, Jing-Wei Yang +7
Hyperbolic superlattices are used for sub-wavelength focusing, cloaking, and optical thermal management. Typically, these superlattices are constructed of layers of noble metals an…
Giant Optical Anisotropy in 2D Metal-Organic Chalcogenates
Bongjun Choi, Kiyoung Jo, Mahfujur Rahaman +6
Optical anisotropy is a fundamental attribute of some crystalline materials and is quantified via birefringence. A birefringent crystal not only gives rise to asymmetrical light pr…
