Coupled-Mode Theory of Multipath Interference in Quasi-Single Mode Fibers
We use the power coupled-mode theory to study the interplay between multipath interference (MPI) and differential mode attenuation (DMA) in quasi-single mode (QSM) fibers.

Oxide-apertured microcavity single-photon emitting diode
We have developed a microcavity single-photon source based on a single quantum dot within a planar cavity in which wet-oxidation of a high-aluminium content layer provides lateral confinement of both the photonic mode and the injection current.

On the Relative Advantage of Mixed-Mode versus Single-Mode Surveys
Survey researchers increasingly use mixed-mode surveys for general population data collection because mixed-mode surveys are argued to provide lower selection error at constant budgets or lower variable costs at constant selection error.

Stability Conditions and the Single Mode Approximation in FQHE
A thermodynamic stability criterion for the spontaneous breaking of the translation invariance of many particle systems is derived. It simply requires the positive character of the wavevector dependent dielectric function as generalising the same ...

In this paper we consider a system consisting of a two-level atom in an excited state interacting with two modes of a radiation field prepared initially in $l$-photon coherent states.

Single-mode coherent synchrotron radiation instability
The microwave instability driven by the coherent synchrotron radiation (CSR) has been previously studied [S. Heifets and G. V. Stupakov, Phys. Rev. ST Accel.

Single Transverse Whispering-Gallery Mode AlGaInAs/InP Hexagonal Resonator Microlasers
AlGaInAs/InP hexagonal resonator microlasers with an output waveguide connected to one vertex of the hexagon are fabricated using standard photolithography and inductively coupled plasma (ICP) etching process.

Mode Optimization and Polarization Control in VCSELs with Sub-Wavelength Gratings
We have demonstrated the integration of sub-wavelength gratings (SWG) into a 795 nm vertical cavity surface emitting laser (VCSEL) with inverse surface relief to achieve coordinated control of the mode and polarization. At a grating period of around 0.5 &

Optimal detection of losses by thermal probes
We consider the discrimination of lossy bosonic channels and focus to the case when one of the values for the loss parameter is zero, i.e., we address the detection of a possible loss against the alternative hypothesis of an ideal lossless channel.

Bulged CH3NH3PbBr3 Microwires for Single‐Mode Lasing
Herein, the lasing action of fabricated bulged CH3NH3PbBr3 microwires is demonstrated with features of a low threshold, narrow linewidth, single‐mode operation, and high intensity.
