Nanostructured Surface Phonon Polariton Systems for Mid-Infrared Nanophotonics

July 1, 2016
Author(s)
Alexander Giles, Richard Kasica, Joshua Caldwell
In this article, novel, phonon-based silicon carbide nanopillar antenna arrays are described. Using fabricated SiC structures, sub-diffractional, localized resonances are observed with exceptionally high quality factors (40-305) and corresponding high

Optical Tracking of Nanoscale Particles in Microscale Environments

March 10, 2016
Author(s)
Pramod Mathai, James A. Liddle, Samuel M. Stavis
The trajectories of nanoscale particles through microscale environments record useful information about both the particles and the environments. Optical microscopes provide efficient access to this information through measurements of light in the far field

Imaging Nanophotonic Modes of Microresonators using a Focused Ion Beam

January 15, 2016
Author(s)
Kevin A. Twedt, Jie J. Zou, Marcelo I. Davanco, Kartik A. Srinivasan, Jabez J. McClelland, Vladimir A. Aksyuk
Optical microresonators have proven powerful in a wide range of applications, including cavity quantum electrodynamics, biosensing, microfludics, and cavity optomechanics. Their performance depends critically on the exact distribution of optical energy

Fiber Bragg Grating Based Thermometry

October 1, 2015
Author(s)
Zeeshan Ahmed, Bernard J. Filla, William F. Guthrie, John S. Quintavalle
In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature

Towards Reproducible Ring Resonator Based Temperature Sensors

September 1, 2015
Author(s)
Nikolai Klimov, Michaela Berger, Zeeshan Ahmed
In recent years photonic devices have emerged as a powerful tool for developing novel, high-sensitivity sensors. In particular, tremendous progress has been reported in developing photonic temperature sensors using a wide variety of materials including

On-Chip Silicon Waveguide Bragg Grating Photonic Temperature Sensor

August 4, 2015
Author(s)
Nikolai Klimov, Sunil Mittal, Zeeshan Ahmed, Michaela Berger
Resistance thermometry is a time-tested method for temperature measurements. Fundamental limits to resistance-based approaches, spurred our interest in developing photonic temperature sensors as a viable alternative. In this study we demonstrate that our
