Nanoscale photonics relates to the ability of patterning matter, particularly semiconductors, to the sub-micron scale in order to realize ultimate miniaturized devices. General scaling considerations imply a drastic decrease of the energy budget required for triggering a fast nonlinear response. These expectations have been confirmed experimentally leading to novel devices such as ultra-fast optical gates, microwave photonic oscillators, optical parametric oscillators. All these devices features microwatt power budget for operation and few micrometers footprint and Gigahertz bandwidth.
We will focus on the recently demonstrated Photonic Crystal Optical Parametric Oscillator and its related technology. We'll discuss their suitability for quantum applications, in particular for quantum information. We will also discuss the use of Optomechanical Crystals as high-purity oscillators and related techniques.
