Proposed topics of the internship:

In the Singular Optics Group, we center our research around laser beam shaping. We develop techniques, algorithms, and supply our laboratory with tools that allow us to pursue the concept of purposefully tailored beams. In particular, we are interested in structured light containing phase singularities—points in the optical field where the phase is undetermined (e.g. optical vortices). We both design, explore and apply these fields in various scenarios, ranging from metrology and wavefront sensing to free space communication protocols.

The proposed project will be devoted to the same concept. The student will have an opportunity to learn modern beam-shaping techniques, mainly using digital holography. They will then realize their own project dedicated to the characterization of structured light, including orbital angular momentum modal analysis or vector fields polarimetry.

Proposed topics of the internship: Investigations of two-photon vision – a perception of light based on two-photon absorption. Pulsed near-infrared laser beams are perceived as having a color of their half-wavelength counterparts. The effect can be used in ophthalmic diagnostics and augmented reality glasses. The student will participate as an operator in psychophysical measurements on a two-photon vision test system at the Institute of Physics at the Nicolaus Copernicus University in Torun. The light source is a tunable OPO (optical parametric oscillator) that allows obtaining the full spectrum of two-photon stimuli (850-1300 nm). Measurements of adaptation to darkness and brightness of two-photon stimuli at different background intensities are planned. The study will allow to distinguish the degree of stimulation of cones and rods in the process of two-photon light perception.

Internship Hosting Organization: University of Warsaw

Proposed topics of the internship:
This project is focused on the, so far unexplored, issue of stationary and dynamically-persistent nonlinear modes in 1D, and 2D systems with a spin-orbit coupling, in which non-hermitian effects are included. We will focus on structured photonic fibers with PT symmetry, and in Bose-Einstein condensates with spin-orbit couplings (SOCs) trapped in PT symmetric external potentials.
We plan to analyze possibility of experimental realization of the (PT) symmetric dynamics in fibers with multiple cores and eventually prepare experiment. In the beginning we will consider the simplest case of two core fiber, ensuring that each core has its own functionality. The first core will play a role of a gain channel and the second one will be lossy, both with tunable characteristics. Theoretical (including simulations) and experimental work (in the laboratory of prof. Buczynski from Physics Department) can be included. It is a current subject of our investigations.

Proposed topics of internship: 

We aim to understand the fundamental physical properties of novel quantum emitters, such as defect centers in layered materials or atomic defects in diamond and gallium nitride. Toward this end we plan to study them with resonant spectroscopy techniques. High order nonlinear optical signals, that provide the most complete set of information, are so far too weak to be measured for such defects. We want to change this by functionalization of the emitters with an open cavity with a small mode volume.

The main task of the project will consist of developing a novel microscopy technique that combines the efficiency of a solid immersion lens with the flexibility of a scanning confocal microscope. This will enable efficient collection of signals from quantum emitters that are either freestanding or embedded in low mode volume and high finesse open microcavity.
