Abstract

In this work, we discuss experimental developments using optomechanical devices. Initially, we explore the classical regime, probing circular devices in a gallium arsenide platform. We develop the fabrication of simple and nanostructured microdisks. It reduces the number of steps while keeping high optical confinement and increasing mechanical frequencies and the optomechanical coupling constant. We show how to reach the sideband resolved regime using these devices. Moreover, we use silicon devices to explore the optomechanical interaction as a quantum phenomenon. We use a pulsed optomechanical interaction and propose and prove the first optomechanical quantum teleportation, paving the way to the use of optomechanical devices as a node in a quantum network. Finally, we develop bi-dimensional silicon devices, exploring the crystalline features of this type of geometry in the quantum regime (AU)
