Abstract: (2924 Views)
In this work, the electro-absorption (EA) process of hybrid structure consisting of metal nano particle (MNP) coupled to multi-layer spherical quantum dot (MSQD) is investigated numerically. The effect of MNP near MSQD is calculated by considering local field enhancement. Then the variation of EA process of hybrid system is studied. The results show that the presence of MNP in the vicinity of MSQD enhances the optical nonlinearity. Also, by changing the radius of MNP, the variations of optical nonlinearity are reported.
