我们报道了一种全新的全光开关，该光开关是在半导体多量子阱中基于激子和双激子能级形成的EIT效应，利用量子相干相消效应来减小材料对探测光场的吸收，且探测光场吸收的强度可以通过控制光场来调节。若将控制光场设置为脉冲光场，则可以实现探测光场的开关调制，通过选取适当的控制光场的强度，可以得到约86%的开关效率。  We report a new all-optical switching. The all-optical switching is based on EIT effect of semiconductor multiple quantum wells exciton energy levels, the use of quantum coherence effects can reduce the absorption of the probe light field, and the intensity of the absorption for the probe light field can be adjusted by the control light field. If the control light field is pulse light field, the all-optical switching can be performed. We can select the appropriate intensity of control light field; the efficiency of switching can reach at almost 86%.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. A relativistic study on lifetime of resonant tunneling states in the case of the double barrier system consisting of rectangular potential barriers has been studied. This study reveals the fact that as compared to the non-relativistic resonant tunneling states the relativistic resonant states occur in the lower energies but they are having shorter lifetime..

Research Article Continuous Interpolation of Solution Sets of Lipschitzian Quantum Stochastic Differential Inclusions

E. O. Ayoola, John O. Adeyeye

Given any finite set of trajectories of a Lipschitzian quantum stochastic differential inclu-sion (QSDI), there exists a continuous selection from the complex-valued multifunction associated with the solution set of the inclusion, interpolating the matrix elements of the given trajectories. Furthermore, the difference of any two of such solutions is bounded in the seminorm of the locally convex space of solutions. Copyright © 2007 E. O. Ayoola and J. O. Adeyeye.
