TL;DR: In this article, the authors studied the influence of current spreading, injected current density, gain-guided aperture, and window diameter on the transverse modes of VCSELs.
Abstract: Transverse-mode control of vertical-cavity surface-emitting lasers (VCSELs) has been investigated A theoretical model takes into account the distributions of carriers, optical field, and temperature Using a method of finding self-consistent solutions for the carrier diffusion, optical field, and thermal conduction equations, we have studied the influence of current spreading, injected current density, gain-guided aperture, and window diameter on the transverse modes The calculated results agree well with those of experiments and show that the transverse-mode evolution of VCSELs depends on the changes of gain and refractive index induced by carriers and heating; decreasing temperature rise and profile width, current spreading, and gain-guided aperture dimension, increasing homogeneity of the injected carriers at the lasing region, and decreasing window diameter are effective methods to suppress high-order transverse modes

TL;DR: In this article, a simple and inexpensive method is proposed to measure time-averaged concentrations under waves, which is defined by sucking samples in a direction normal to the ambient water motion at an intake velocity which exceeds the ambient flow velocity more than three times.

TL;DR: A comparison between a theoretical model based on the conservation of energy and experimental measurements shows good agreement simultaneously for longitudinal (Goos-Hänchen) and transverse (Imbert-Fedorov) displacements.
Abstract: We describe a simple experimental setup with which to observe the transverse shift—also known as the Imbert-Fedorov effect—that circularly or elliptically polarized optical beams undergo after a single total internal reflection on a dielectric plane. A comparison between a theoretical model based on the conservation of energy and experimental measurements shows good agreement simultaneously for longitudinal (Goos-Hanchen) and transverse (Imbert-Fedorov) displacements.

TL;DR: In this paper, a simple theory for bending composite anisotropic plates that are laminated symmetrically about their midplane is presented, which incorporates transverse shear deformation and transverse normal stress as well as the higher-order effects.

TL;DR: In this paper, the in-plane vibration of a slider-mass which is driven around the surface of a flexible disc, and the transverse vibration of the disc, are investigated, showing that normal pressure and rotating speed can drive the system into instability.
