Super-Homogeneous Saturation of Microwave-Photonic Gain in Optoelectronic Oscillator Systems
IEEE Photonics Journal, 2012 We show that the saturation characteristic of microwave-photonic gain is “super-homogeneous” such that the gain of a weaker tone saturates more rapidly than that of a stronger tone when both signals are transmitted over an intensity ...

Linear and nonlinear capacitive coupling of electro-opto-mechanical photonic crystal cavities [PDF]
, 2014 We fabricate and characterize a microscale silicon electro-opto-mechanical system whose mechanical motion is coupled capacitively to an electrical circuit and optically via radiation pressure to a photonic crystal cavity.

Mode-selective toroidal mirrors for unstable resonator planar waveguide and thin slab solid-state lasers [PDF]
, 2009 In this paper, two new fabrication methods are developed for highly curved toroidal laser resonator mirrors based on laser micromachining of cylindrical substrates that already have the large lateral curvature RT provided by conventional polishing. These

Stacking‐Engineered Magnonic Topology and Transport in Honeycomb Homobilayers
Advanced Functional Materials, EarlyView.ABSTRACT Topological magnons have emerged as a promising platform for dissipationless bosonic transport. However, a straightforward and effective strategy to engineer such topological states in real materials has yet to be fully realized. Here, a general scheme for controlling magnonic topological states via stacking engineering in van der Waals ...

Factors influencing the distribution of charge in polar nanocrystals [PDF]
, 2011 We perform first-principles calculations of wurtzite GaAs nanorods to explore the factors determining charge distributions in polar nanostructures. We show that both the direction and magnitude of the dipole moment $\mathbf{d}$ of a nanorod, and its ...

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties
Advanced Functional Materials, EarlyView.High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐
