In the last several years, rapid advances have been made in the field of cavity optomechanics, in which the usually feeble radiation pressure force of light is used to manipulate (and precisely monitor) mechanical motion [1–3]. These advances have moved the field from the multi-km interferometer of a gravitational wave observatory, to the optical table top, and now all the way down to a silicon microchip [4]. In this talk I will describe these advances, and discuss our own work to realize radiation pressure within nanoscale structures in the form of coupled photonic and phononic crystals (dubbed optomechanical crystals) [5]. Applications of these new nano-opto-mechanical systems include: all-optically tunable photonics, optically powered RF and microwave oscillators, and precision force/acceleration and mass sensing. Additionally there is the potential for these systems to be used in hybrid quantum networks, enabling storage or transfer of quantum information between disparate quantum systems. I will introduce several conceptual ideas regarding phonon-photon translation [6] and slow light effects [7] which may be used in such quantum settings, and discuss recent experiments to realize them in practice [8].

Photonic crystal nanolasers have attracted great interest both for fundamental research and applications in the past decade. In photonic crystal cavities, the leakage to optical modes is strongly reduced, which increases the spontaneous emission coupling factor, β. This is a crucial parameter for the threshold characteristics of lasers. With increasing β, the well-known step-like threshold behavior becomes smoother. Although the smooth lasing transitions of photonic crystal nanolasers were observed and fitted by traditional rate equation models [1], a systematic comparison between experiments and more advanced semiconductor models of photonic crystal nanolasers is still missing [2]. The goal of this work is to get a deep understanding of the quantum dots based nanocavity lasers by comparing experiments to theory.

We report on an experiment underway for generating a singlet state in a cold atomic ensemble. The experiment is based on a recent proposal to generate these states by applying a quantum non-demolition (QND) measurement and feedback to an unpolarized ensemble [1]. Our criteria for generating the singlet state is the spin squeezing parameter equation where Fi are the components of the collective angular momentum, N is the number of atoms and f is the spin of a single particle. Any state with ξs < 1 is an entangled state [2]. Our procedure, described bellow, will lead to a highly entangled state with ξs ≪ 1 starting from a non-entangled state with ξ ∼ 1.

Trapped ions are a major candidate technology for scalable quantum computation. However, current methods for performing quantum logic gates with trapped ions are limited to gate times of about 10 µs. This drawback is overcome in a recently proposed scheme that uses pairs of counter-propagating π-pulses, resonant with an allowed ion transition, where the time needed for a gate operation is inversely proportional to the laser repetition rate [1]. Our MOPA architecture allows scaling to high repetition rate at constant pulse energy.

Drugs influence the human body in many ways. Cocaine (COC), for instance, leads impaired drivers to the tendency for speeding, high-risk behaviour and total loss of control [1]. As a consequence an-easy-to-handle on-site test is necessary to diagnose impaired drivers and reduce car crashes related to the influence of drugs. Another example for a drug of interest would be caffeine. There are extended studies that analyze the connection between caffeine and suicidal, maniac and schizophrenic behaviour as well as depressions [2]. For research in this field it would be helpful to monitor the caffeine level with a non-invasive method.

Metal nanostructures supported on dielectric substrates have attracted great interest as building blocks of nanoscale optical devices such nano-plasmonic devices or planar metamaterials. In this framework artificial circular dichroism [1] is investigated for developing novel devices for active polarization controllers, like rotators and modulators and high efficient molecular sensors. Here we report the experimental observation of nonlinear extrinsic chirality [2] (circular dichroism) of the second harmonic (SH) field generated by self-organized gold nanowire arrays with sub-wavelength periodicity [3]. In this material the chirality arises from the curvature of the self-assembled wires, producing a lack of symmetry at oblique incidence [2]. Such circular dichroism in the SH field is the evident signature of the sample morphology and can be used in order to develop more efficient molecular sensors, based on metal enhanced fluorescence or surface enhanced Raman scattering.

Quantum manipulation using the optical transition (3H4→1D2) of Pr3+ embedded in solid state host materials requires a visible source emitting at 606 nm with a linewidth at the kHz level [1]. In a previous work, we have reported the stabilization of a continuous wave intracavity frequency doubled singly resonant optical parametric oscillator (cw-SHG-SRO) by locking it onto the side of the transmission fringe of a medium finesse Fabry-Perot (FP) cavity [2]. In this scheme, the signal transmitted by the FP cavity was not only sensitive to any frequency fluctuation but also to any change in the source power, which can be misinterpreted as a frequency fluctuation.

In the textbook case of normal diffusion, transport is described as a randomwalk to which all the steps give the same contribution (Brownian motion). Superdiffusion occurs when the transport is dominated by a few, very large steps (Lévy flights). In this regime the variance of the step length distribution diverges and the mean square displacement grows faster than linear with time [1]. Previous works have evidenced the peculiar statistical properties of Lévy motions and shown that several features of real experiments, such as properly defined boundary conditions, are nontrivial to implement [2], making the description of observable quantities nearly impossible.

Multi-mode photonic lightwave circuits (PLCs) provide new avenues for extending the performance of single mode systems. As an example, they can potentially provide increased bandwidth by multiplexing information into different waveguide modes[1]. For practical applications of multi-mode PLCs to be developed, a measurement technique is required to investigate detailed mode profiles and propagation constants in complex circuits. Photon scanning tunnelling microscopy (PSTM) provides a means of experimentally tracking the femtosecond inter-modal delays observed in PLCs with the ability to discriminate modes by their spatial profiles inside the waveguide.

Photonic crystals are very suitable for controlling radiation field and propagation characterization of light. As an important application, it is ultra compact and ultrafast optical integrated circuits (OIC) based on photonic crystals slab waveguides (PC-WGs) composing of the line-defects [1, 2]. The PC-WG is also attractive for laser lasing, because very small group velocity of near the Brillouin zone (BZ) edge should enhance interactions between the radiation field and matter. Indeed, the lasing spectrum has been observed from optically pumped InAs-quantum dots (InAs-QDs) embedded in PC-WG of the multimode W3 type (three rows missing line-defect) [3]. In the present study, we observe laser action in InAs-QDs PC-WG of the single-mode W1 type (single row missing line-defect).
