Superresolution fluorescence microscopy with structured illumination
The resolution of a conventional fluorescence microscope image is diffraction limited which achieves a spatial resolution of 200nm lateral and 500nm axial. Recently, many superresolution fluorescence microscopy techniques ...
Quantum memory protocols for photonic solid-state devices
A photonic quantum memory (QM) is a device that has the capability of storing a quantum state of light and retrieving back after a controlled time. It is an important element in quantum information science and is, among ...
Quantum information with black boxes : lifting protocols from theory to implementation
According to recent estimates, 10^18 bytes of data are generated on a daily basis around the globe. Our information society urges for radical solutions to treat such data deluge. By exploiting fundamental key elements of ...
New systems for quantum nonlinear optics
Photons travelling through free space do not interact with each other. This characteristic makes them perfect candidates to carry quantum information over long distances. On the other hand, processing the information they ...
Strong-field processes in atoms and polyatomic molecules
In this thesis, we develop a general theory to describe the dynamics of electrons that are ionized when an atom or molecule is exposed to a strong low frequency laser field. Our approach extends and improves the well-established ...
Nanophotonics of ultrathin films and 2D periodic structures: a combined experimental and theoretical study
Photonics is a key enabling technology for many applications ranging from communications to energy and medicine. Its success is largely relying on our capability to appropriately control light in optical devices. To this ...
Cavity optomechanics with optically trapped particles
Optical trapping and manipulation have emerged as powerful tools to investigate single microscopic objects in a controlled environment. Using the momentum carried by light, forces can be exerted to confine and manipulate ...

Understanding and improving how light is converted into electricity in materials is one of the central goals in the field of optoelectronics. This basic physical process lies at the heart of several major technologies, ...
Single domain spinor Bose-Einstein condensate
This work reports on the construction of a new-generation system capable to create single-mode spinor Bose-Einstein condensates of 87Rb, and non-destructively probe them using optical Faraday rotation. This system brings ...
High power, high intensity few-cycle pulses in the mid-IR for strong-field experiments
High-energy, few-cycle, mid-lR radiation sources featuring high pulse repetition rates are of tremendous interest for a variety of strong-field physics and attoscience applications. Such systems could be used in combination ...
Hybrid photonic-plasmonic devices with single nanoscale light sources
The field of photonics comprehends the generation, manipulation and detection of light (photons). Over the past decades, it has underpinned many of the technological advances upon which we rely on a daily basis, from our ...
Self-cleaning optical surfaces for the inkjet and 3D printing industry
Liquid and solid repellent surfaces are key to many industries. For example, construction industry benefits from self-cleaning windows, cements, paints, roof tiles, and corrosion resistant surfaces, while easy-to-clean, ...
Exploring flatland nano-optics with graphene plasmons
Plasmons are charge oscillations coupled to electromagnetic radiation. One of their most intriguing properties is their deep subwavelength confinement resulting in strongly enhanced light-matter interaction. Metal plasmons ...
Multi-junction thin film solar cells for an optimal light harvesting
Thin film photovoltaics encompass a group of technologies able to harvest light within a few microns thickness. The reduced thickness allows a low cost of manufacture while making the films flexible and adaptable to ...
Insights on the spatiotemporal organization of integrins and their ligands using quantitative biophysical tools
The migration of leukocytes from the blood stream to sites of injury and infection in the extravascular tissues is fundamental for the immune response. Two of the main receptors mediating this process are the integrins ...
A quantum light-matter interface with Rydberg polaritons in a cold atomic ensemble
Nonlinear optics at the single-photon level enables deterministic photonphoton interaction, a long-standing goal in quantum photonics science. Besides its implication in fundamental aspects of physics, this would unlock ...
