Non-linear Study of Zinc Oxide Quantum Dot for Optoelectronics Applications

The nanostructures are being used for the various nonlinear optical devices. In this paper we have studied the few nonlinearities of ZnO quantum dots considering susceptibility as the nonlinear parameter and the equation for the second order nonlinearity of quantum dots have been developed and simulations have been performed for second order susceptibility in terms of dot size, photon energy, and electric field. We found that the second order coefficient gets a higher value for a particular value of length L only. If the value of length L gets above or below that, a lower value of susceptibility is obtained. These effects will be useful for the applications in photonics devices like lasers, solar cells, resonators etc.
