A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications
photonic crystal cavity-optical fiber tip nanoparticle sensor biomedical applications Optics
2012/4/19
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from a nanoparticle solut...
Optical transitions in highly-charged californium ions with high sensitivity to variation of the fine-structure constant
Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics
2012/4/19
We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...
Non-detection of the Tooth Fairy at Optical Wavelengths
Photometry multi-wavelength studies magical creatures Individual Instrumentation and Methods for Astrophysics
2012/4/19
We report a non-detection, to a limiting magnitude of V = 18.4 (9), of the elusive entity commonly described as the Tooth Fairy. We review various physical models and conclude that follow-up observati...

optical nanoantennas Yagi-Uda antennas all-dielectric nanoantennas plasmonics nanoparticles spectral tuning Purcell factor
2012/4/19
Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optical nanoantennas made...
The analogy between optical beam shifts and quantum weak measurements
analogy between optical beam shifts quantum weak measurements Optics
2012/4/19
We describe how the notion of optical beam shifts (including the spatial and angular Goos-H\"anchen shift and Imbert-Federov shift) can be understood as a classical analogue of a quantum measurement o...
Columnar Optical Depth and Vertical Distribution of Aerosols over Shanghai
Aerosol optical depth Vertical extinction profile CALPSO/CALIOP
2016/3/25
The vertical distributions and optical properties of aerosols over Shanghai were analyzed using data from ground-based
observation, space remote sensing and trajectories. Measurements of spectral aer...
Optical Magnetometer Array for Fetal Magnetocardiography
Optical Magnetometer Array Fetal Magnetocardiography
2012/2/28
We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are configured with a small...

Circularly polarized light chiral glucose scattering coefficient tissue phantom human subjects
2012/2/28
A device based on Polarization sensitive optical coherence tomography is developed to monitor blood glucose levels in human subjects. The device was initially tested with tissue phantom. The measureme...
A Study of Optical Observing Techniques for Extra-Galactic Supernova Remnants: Case of NGC 300
Optical Observing Techniques Extra-Galactic Supernova Remnants NGC 300
2012/2/21
We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC 300. The goal...
Deformation during the 1975–1984 Krafla rifting crisis, NE Iceland, measured from historical optical imagery
Krafla rifting crisis IN Iceland measured historical optical imagery
2014/4/15
We measure the displacement field resulting from the 1975–1984 Krafla rifting crisis, NE Iceland, using optical image correlation. Images are processed using the COSI-Corr software package. Surface ex...
The feasibility of directly overwriting certain magneto-optical recording materials without the use of an external magnetic field has recently been demonstrated in our laboratory.In this report experi...
The coercivity of amorphous rate earth-transition metal magneto-option (MO) recording media has been measured as a function of position on the films utilizing a micro-Kerrhysteresis-loop-tracer with a...
Effects of substrate bias on the magnetic properies and microsture of both rf-magnetron and dc-magnetron sputtered magneto-optical recording thin films of TbCo were investigated.It is shown that as an...
Recording Characteristics of (Dy,Tb)FeCo disks were studied.'Anisotropy dispersion' of rare earth constituents such as Gd,Tb,and Dy qualitatively accounts for domain wall mobility and domain size.Resu...
A vector diffranction medel has been applied to analyze CAD readout of MSR disks.Numerical results indicate that the read power is optimized with an aperture of the same size as the recorded mark.CNR ...
