An electroabsorption modulator using the intrastep quantum well (IQW) active region is fabricated for optical network systems. The strain-compensated InGaAsP/In
We calculate the exciton binding energy and interband optical absorption in a rectangular coupled quantum wire under the hydrostatic pressure in the effective-m
We study the four-wave mixing(FWM)in an opening five-level system with two dressing fields.There are threekinds of doubly dressing mechanisms(parallel cascade,s
Efficient red polymer light-emitting diodes are fabricated with the single active layer from the blends of poly (Nvinylcarbazole) (PVK) in the presence of 30wt.
Multiwavelength dispersion-tuned actively mode-locked erbium-doped fibre ring laser is demonstrated by incorporating a section of highly nonlinear fibre (HNLF)
