In this paper, the modified Kudryashov method is applied for obtaining the exact travelling wave solutions for the (2 + 1)-dimensional Heisenberg ferromagnetic spin chain equation and the complex Klein–Gordon equation. The extracted solutions show distinct physical configurations. More precisely, the modified Kudryashov method is utilized for constructing the exact periodic and soliton solutions of...
We demonstrate an optical comb source made out of 500 in-phase and ultra-narrow spectral lines spanning over 32 nm. The source results from a single mode Brillouin laser processed with phase modulation, pulse compression, four wave mixing and regeneration. The narrow linewidth of the Brillouin laser was replicated throughout the frequency comb spectral lines.
We demonstrate an optical fiber Brillouin laser operating over several stokes orders. Experimental results agree well with theoretical modelling. The spectrum shows up to six stable Stokes Brillouin orders within 10 dB below of the pump peak power.
In this work, a computational model for optimization of material gain of the active region of a multiple quantum well (MQW) edge emitting laser (EEL) using genetic algorithm has been developed. Through this optimization procedure, the values of the width of quantum wells (QW), width of barriers, lattice temperature, injection carrier density and number of QWs which are related to material gain of...
Silicon nanowire arrays have been shown to demonstrate light trapping properties and promising potential for next-generation photovoltaics. In this paper, we show that the absorption enhancement in vertical nanowire arrays on a perfectly electric conductor can be further improved through tilting. Vertical nanowire arrays have a 66.2% improvement in ultimate efficiency over an ideal double-pass thin...
