Abstract Possibility of tailoring the light-current characteristic (LCC) shape in quantum dot (QD) lasers by varying uniformity QDs is discussed. Making QD ensemble less uniform results roll-over LCC. The second branch LCC appears with making even uniform.

A 17.8–34.8 GHz (64.6%) locking range current-reuse injection-locked frequency multiplier (CR-ILFM) with dual injection technique is presented in this paper. applied to generate differential signal and increase the power of second-order harmonic component. The CR core proposed reduce consumption compatibility NMOS PMOS injectors. inductor-capacitor (LC) tank CR-ILFM designed a fourth-order reso...

In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...

In laser structures where the active region consists of several quantum wells, non-uniform charge injection can occur. We examine the consequences of non-uniform charge injection on gain, threshold current, and linewidth enhancement factor. Non-uniform charge injection in a InP-based multiple quantum well laser was considered in order to analyze effects on gain, threshold current, and linewidth...
