Near-field imaging and frequency tuning of a high-Q photonic crystal membrane microcavity

, 2007
We discuss experimental studies of the interaction between a nanoscopic object and a photonic crystal membrane resonator of quality factor Q=55000. By controlled actuation of a glass fiber tip in the near-field of a photonic crystal, we constructed a ...

Kinetic Insights into Precursor‐Assisted Soft Sphere Close Packing Revealed by In Situ GISAXS with Implications for Gas Sensing

Advanced Functional Materials, EarlyView.
The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.

Spontaneous emission in the near-field of 2D photonic crystals

, 2005
We show theoretically that photonic crystal membranes cause large variations in the spontaneous emission rate of dipole emitters, not only inside but also in the near-field above the membranes.

A new slant on photonic crystal fibers

Optics Express, 2004
We present the novel use of microstructured optical fibers not as 'light-pipes', but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

Advanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Nanobeam photonic crystal cavity quantum dot laser [PDF]

, 2010
The lasing behavior of one dimensional GaAs nanobeam cavities with embedded InAs quantum dots is studied at room temperature. Lasing is observed throughout the quantum dot PL spectrum, and the wavelength dependence of the threshold is calculated.
