Direct Frequency Modulation In AlGaAs Semiconductor Lasers
Direct frequency modulation characteristics in three different AlGaAs lasers - a channeled-substrate planar (CSP) laser, a buried-heterostructure (BH) laser, and a transverse-junction-stripe (TJS)Expand

LASERS, OPTICS, AND OPTOELECTRONICS 2865 Single-mode solid-state single photon source based on isolated quantum dots in pillar microcavities
We report the fabrication of a single-mode solid-state single photon source, based on an isolated InAs quantum dot (QD) on resonance with the fundamental mode of a pillar microcavity. PhotonExpand

Birefringence and polarization characteristics of single-mode optical fibers under elastic deformations
Birefringence and polarization dispersion caused by: 1) elliptical core, 2) twist, 3) pure bending, 4) transverse pressure, and 5) axial tension are studied by treating these deformations asExpand

Birefringence caused by thermal stress in elliptically deformed core optical fibers
Birefringence and polarization dispersion introduced by thermal stress in single-mode fibers with elliptical core are formulated here in terms of fiber structure parameters, thermal expansionExpand

One-dimensional Wolter optics with a sub-50 nm spatial resolution.
We studied an imaging system consisting of an elliptical mirror and a hyperbolic mirror [i.e., one-dimensional (1D) Wolter optics] to realize an achromatic full-field hard x-ray microscopy with aExpand

2 Gbit/s optical transmission experiments at 1.3 μm with 44 km single-mode fibre
GeAPD optical receiver sensitivity at 1.3 μm was studied up to 2 Gbit/s. High sensitivity of the receiver and a low coupling loss of 4 dB between a laser and a single-mode fibre achieved by aExpand

Spatial hole-burning effects in a Nd 3+ :YAG laser
The concept of spatial hole burning in the population inversion distribution of a solid-state laser was introduced by Tang et al in 1963 [3]. In this paper, several aspects of the spatialExpand

Degree of polarization in anisotropic single-mode optical fibers: Theory
The degree of polarization for propagation waves in anisotropic single-mode fibers is formulated in terms of light source spectrum, incident polarization condition, and fiber parameters. TheExpand

Polarisation conservation in single-mode fibres
There exist proper orthogonal elliptical polarisation states, which are maintained over long fibre length without converting. When one of the proper polarisation states is excited, orthogonalExpand
