Nanostructured spectral filters enabling dynamic color-tuning are saliently attractive for implementing ultra-compact color displays and imaging devices. Realization of polarization-induced dynamic color-tuning via one-dimensional periodic nanostructures is highly challenging due to the absence of plasmonic resonances for transverse-electric polarization. Here we demonstrate highly efficient dy...

Abstract The polarizations of optical fields, besides field intensities, provide more degrees freedom to manipulate coherent light–matter interactions. Here, we propose how achieve a switch optomechanical entanglement in polarized-light-driven cavity system. We show that by tuning the driving field, effective coupling can be well controlled and, as result, quantum between mechanical oscillator ...

Ab&&--The dispersion equation for a whistler mode propagation in a warm plasma, subjected to parallel static electric and magnetic fields, is derived by using a linearized coupled VlasovMaxwell equation. From the derived dispersion equation, the amplitude constant CL and phase constant B of the whistler mode are expressed in terms of static electric field Es, static magnetic field B,, the elect...

The output beam quality of multi transverse modes of laser, are relatively poor. In order to obtain better beam quality, one may use an aperture inside the laser resonator. In this case, various transverse modes can be selected. We have selected various transverse modes both by simulation and doing experiment. By inserting a circular aperture inside the diode end-pumped Nd:YAG pulsed laser reso...

An LWD acoustic wave can move the excess charge in the electric double layer along the borehole wall to generate a streaming electric field. This thesis is an experimental and theoretical investigation of the electric field induced by the multipole LWD acoustic wave. The main goal of this thesis is to understand the mechanism in the seismoelectric conversion under the LWD geometry and prove the...

A theoretical proposal to double the pulse repetition frequency by alternated current modulation of two orthogonal high order transverse modes of a vertical cavity surface emitting laser (VCSEL) is presented. Static and dynamic characteristics of weakly index guided VCSELs in a multitransverse mode regime are analysed. An eecient model that takes into account all the transverse modes supported ...

We develop a mesoscopic model of semiconductor dynamics for vertical-cavity surface-emitting lasers which allows us to describe polarization and transverse mode dynamics simultaneously. Within this model, we study the selection processes and the turn-on delay for the switch-on of di erent transverse modes in gain-guided VCSELs. We consider di erent active-region diameters, excitation conditions...
