Quantum optics

Entanglement is one of the most counterintuitive phenomena in quantum physics. We study the physics of highly entangled photons in complex systems, and explore how they can be harnessed for novel quantum technologies. read more

Fiber optics

Optical fibers are an attractive solution for meeting the ever-growing demand for high-bandwidth, low-loss, reliable technology. They are at the heart of many day-to-day technologies, such as data transfer and medical endoscopes. Studying the physics of such systems is key for overcoming the inherent challenges they present. read more

Light in random media

Thick random samples like human skin, white paint or clouds, are opaque, as most of the light that illuminates them is backscattered. We develop methods to cancel the effect of scattering for imaging and communication application. read more

Nonlinear optics

The interplay between nonlinearity, disorder and interference exhibits fascinating and rich physics. Multimode optical fibers are a perfect testbed for studying such phenomena, as they exhibit strong nonlinearity and random mode mixing. We launch into the fiber ultrashort optical and explore the role of mode-mixing in nonlinear processes such as white light generation, spontaneous four-wave mixing and self-phase modulation. read more

Quantum technologies

Quantum key distribution (QKD) is an advanced technology that provides ultimate secure communication by exploiting quantum states of light as information carriers. In early QKD protocols, each bit of the key was encoded using a two-dimensional quantum. We study and implement advanced QKD protocols that are based on encoding the key in d-dimensional quantum states, called qudits. The higher information capacity of qudits allows a higher secure key rate and improves the robustness of the key distribution protocols to the noise, leading to higher threshold values for the quantum bit error rate (QBER). read more
