Abstract: A discrete-time two-user interference channel model is developed that captures non-linear phenomena that arise in optical fiber communication employing wavelength-division multiplexing (WDM)...
Spectral Singularities of a Complex Spherical Barrier Potential and Their Optical Realization
Complex potential spectral singularity zero-width resonance gain medium threshold gain spherical dye laser
2011/8/31
Abstract: The mathematical notion of a spectral singularity admits a physical interpretation as a zero-width resonance. It finds an optical realization as a certain type of lasing effect that occurs a...

Discovering the missing 2.2optical variability and optical/near-IR colors
Discovering missing quasars combining variability optical/near-IR colors
2011/9/27
The identifications of quasars in the redshift range 2.2icient as their optical colors are indistinguishable from those of stars. Recent studies have proposed to use opt...

2011/9/27
[Abridged] We present ground-based MDM V-band and Spitzer/IRAC 3.6um-band photometric observations of the 72 representative galaxies of the SAURON Survey. In combination with the SAURON stellar veloci...
A scanning probe-based pick-and-place procedure for assembly of integrated quantum optical hybrid devices
probe-based pick-and-place procedure assembly integrated quantum optical hybrid devices
2011/8/2
Abstract: Integrated quantum optical hybrid devices consist of fundamental constituents such as single emitters and tailored photonic nanostructures. A reliable fabrication method requires the control...
Perturbation Theory for PT-Symmetric Sinusoidal Optical Lattices at the Symmetry-Breaking Threshold
