The application of high-count multi carrier optical sources (i.e. frequency combs) in real-time microwave/millimeter wave signal processing is discussed. The multi heterodyne sensing and classification of up to 110 GHz-wide radio frequency (RF) signals using two set of optical frequency combs is demonstrated.

A novel holographic-based sensing system for the determination of aerosol particle number concentrations is presented. A model was designed to support both the development of a new counting algorithm and the conception of a measurement setup.

Using a non-collinear FOPA, a source delivering 1.8 μm, 30 mJ, 13 fs laser pulses is demonstrated. This is the first step towards 100 mJ for ∼10 TW. This laser opens the way for high brightness soft X-ray attosecond pulses.

We investigate the existence and stability of moving gap solitons in a dual core system where one core has only Kerr nonlinearity and the other one is linear and has a Bragg grating with dispersive reflectivity.

We demonstrate a single-comb Fourier transform spectrometer by sweeping the pulse repetition frequency of an electro-optic frequency comb. Such combs are more flexible than mode-locked lasers in terms of tunability of the comb repetition rate, which provides an advantage for comb based spectroscopy.

We propose a novel spectrum analyzer based on heterodyne down-conversion with two detuned optical frequency combs for rapid, wideband characterization of RF signals. The measurement bandwidth of ∼40GHz is limited by modulator speed and the system latency and frequency resolution are time-bandwidth limited.

We demonstrate low surface recombination velocity (∼8700 cm/s) and reduction of non-radiative lifetime in an InP/InGaAs nanoscale light emitting diode using a sacrificial Al2O3 layer. We predict high efficiency operation after modest enhancement of spontaneous emission rate with an optical antenna.

We implement numerical back-propagation of the experimentally obtained spatial complex coherence function to estimate both the axial and transverse positions of 1D objects. The measurement of the coherence function of partially coherent light is performed using dynamical double slits implemented via digital micromirror device.
