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 ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Perovskite Light‐Emitting Diodes with Quantum Wires and Nanorods
Advanced Materials, EarlyView.This review focuses on low‐dimensional perovskite materials and discusses their applications in light‐emitting diodes (LEDs). Special attention is given to the introduction of perovskite quantum wires and nanorods, two unique types of one‐dimensional (1D) materials, and their interesting optoelectronic properties.

Optoelectronic Devices for In‐Sensor Computing
Advanced Materials, EarlyView.The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

Wakefields in photonic crystal cavities
Physical Review Special Topics. Accelerators and Beams, 2009 Simulations of charged particle beams in accelerator cavities show that a two-dimensional photonic crystal can be used to create a three-dimensional hybrid cavity with a single operating mode and no significant higher order modes, greatly reducing long ...
