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,…
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…
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…
