Quantum suppression of shot noise in field emitters [PDF]
, 2003 We have analyzed the shot noise of electron emission under strong applied electric fields within the Landauer-Buttiker scheme. In contrast to the previous studies of vacuum-tube emitters, we show that in new generation electron emitters, scaled down to ...

Exciton Footprint of Self-assembled AlGaAs Quantum Dots in Core-Shell Nanowires [PDF]
, 2014 Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilities. Here, we study the fine structure of gallium-rich quantum dots nested

Emittance theory for cylindrical fiber selective emitter [PDF]
AIP Conference Proceedings, 1999 A fibrous rare earth selective emitter is approximated as an infinitely long, cylinder. The spectral emittance, e(sub x), is obtained L- by solving the radiative transfer equations with appropriate boundary conditions and uniform temperature. For optical depth, K(sub R), where alpha(sub lambda), is the extinction coefficient and R is the cylinder ...

Bright Room-Temperature Single Photon Emission from Defects in Gallium Nitride
, 2016 Single photon emitters play a central role in many photonic quantum technologies. A promising class of single photon emitters consists of atomic color centers in wide-bandgap crystals, such as diamond silicon carbide and hexagonal boron nitride. However,

Dynamical theory of single photon transport in a one-dimensional waveguide coupled to identical and non-identical emitters [PDF]
, 2016 We develop a general dynamical theory for studying a single photon transport in a one-dimensional (1D) waveguide coupled to multiple emitters which can be either identical or non-identical.

Imaging and quantum efficiency measurement of chromium emitters in diamond [PDF]
, 2010 We present direct imaging of the emission pattern of individual chromium-based single photon emitters in diamond and measure their quantum efficiency. By imaging the excited state transition dipole intensity distribution in the back focal plane of high ...
