Low insertion loss modulator based on a vertically coupled photonic crystal resonator [PDF]
, 2012 We experimentally demonstrate a simple but more efficient technique to modulate and multiplex multiple WDM channels. Our design is based on a bus waveguide vertically coupled to multiple Photonic Crystal (PhC) resonator, each of which modulates an ...

Hollow-core photonic band gap fibers for particle acceleration
Physical Review Special Topics. Accelerators and Beams, 2011 Photonic band gap (PBG) dielectric fibers with hollow cores are being studied both theoretically and experimentally for use as laser driven accelerator structures. The hollow core functions as both a longitudinal waveguide for the transverse-magnetic (TM)

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds
Advanced Materials, EarlyView.We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.
