Britain's Payne may have key to all-optical routers

The specific features including high factor and long vibration lifetime of nanomechanical resonator (NR) in nano-optomechanical systems have stimulated research to realize some optical devices. In this work, we demonstrate theoretically that it is possible to achieve quantum memory for light on demand via a quantum dot system coupled to a nanomechanical resonator. This quantum memory for light is based on mechanically induced exciton polaritons, which makes the dark-state polariton reaccelerated and converted back into a photon pulse. Our presented device could open the door to all-optical routers for light memory devices and quantum information processing.

The Common

Till now correlation functions have been used in electron microscopy for two purposes: a) to find the common origin of two micrographs representing the same object, b) to check the optical parameters e. g. the focus. There is a third possibility of application, if all optical parameters are constant during a series of exposures. In this case all differences between the micrographs can only be caused by different noise distributions and by modifications of the object induced by radiation.Because of the electron noise, a discrete bright field image can be considered as a stochastic series Pm,where i denotes the number of the image and m (m = 1,.., M) the image element. Assuming a stable object, the expectation value of Pm would be Ηm for all images. The electron noise can be introduced by addition of stationary, mutual independent random variables nm with zero expectation and the variance. It is possible to treat the modifications of the object as a noise, too.
