Quadratic electro-optic effect and electro-absorption process in CdSe–ZnS–CdSe structure

Influence of noise-binding energy interplay on DC-Kerr effect and electro-absorption coefficient of impurity doped quantum dots

“…Qualitatively similar features have been observed in the DCKE plots without noise and under additive noise. In both these cases we find regular drop of peak altitude and blue-shift of peaks as BE increases [44], [45], [46], [47], [48], [49], [50], [51]. Both of the above changes signify augmentation in the energy separation between the eigenstates and fall of dipole matrix element.…”

“…Here also EAC profiles show similar characteristics without noise and with additive noise. In both these cases EAC peaks undergo blue-shift and their height gradually decreases as BE increases [43], [44], [45], [46], [47], [48], [49]. The observations can be realized on the basis of enhanced energy gap among the eigenstates and reduced magnitude of dipole matrix element.…”

“…Electro-absorption coefficient (EAC) or electro-absorption frequency-dependent susceptibility is another notable third-order nonlinear optical (NLO) quantity to explore the photoemission and detection experiments of QDs [43]. Above facts have inspired lots of relevant works that deal with DCKE [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51] and EAC [43], [44], [45], [46], [48], [49], [50] in LDSS.…”

Investigation of quadratic electro-optic effects and electro-absorption process in GaN/AlGaN spherical quantum dot

“…The third-order nonlinear optical susceptibility χ (3) (- ω , 0, 0, ω ) is a complex function. The nonlinear quadratic electro-optic effect (DC-Kerr effect) and EA frequency dependence susceptibilities are related to the real and imaginary part of χ (3) (- ω , 0, 0, ω ) [ 20 - 22 ].…”

“…The authors of [ 21 , 22 ] studied the quadratic electro-optic effects (QEOEs) and electro-absorption (EA) process in InGaN/GaN cylinder quantum dots and CdSe-ZnS-CdSe nanoshell structures. They have found that the position of nonlinear susceptibility peak and its amplitude may be tuned by changing the nanostructure configuration.…”
