The aim of the Resonators 2023 project is to create a unique internship platform for talented students of disciplines related to optics and photonics, who undertake their studies at polish universities. Interns, selected in an open competition, will receive scholarships to cover the costs of changing their place of residence for the duration of the internship. At the same time, students participating in the project will be covered by a program of specialized training courses aimed at strengthening their soft skills.


Edition 2023

In this year’s edition, Scholars can choose internship project proposals proposed by tutors from the University of Warsaw, Wrocław University of Science and Technology, the International Centre for Translational Eye Research and Polish Technological Platform on Photonics. Candela Foundation plans to fund up to 7 scholarships – each up to 5500 PLN gross.

Who can apply?

Students of disciplines related to optics and photonics. The condition for participation in the program is to complete your internship in a city other than the one in which you are currently studying; in the 2023 edition it is Warsaw, Wrocław and Ożarów Mazowiecki.

Supervisors: dr Tomasz Jakubczyk and Nilesh Dalla

Hosting organization: Faculty of Physics, University of Warsaw (Warsaw) 

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, silicon carbide and gallium nitride. Toward this end we plan to study them with resonant spectroscopy techniques. High order nonlinear optical signals, that provide 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 schemes of lateral femtosecond laser excitation of quantum emitters that are embedded in low mode volume and high finesse open microcavity.
Open tunable optical microcavities, single-photon emitters, finesse, Q factor of a microcavity, resonant spectroscopy

Supervisors: dr Maciej Kowalczyk and dr hab. inż. Jarosław Sotor

Hosting organization: Wrocław University of Science and Technology (Wrocław) 

Proposed topics of internship:

Ultrafast mid-IR lasers for biomedical applications
Ultrafast pulsed lasers have made it possible to generate the shortest events mankind has ever produced. In our group, we are developing state-of-the-art laser sources that generate ultrashort pulses in the mid-infrared (mid-IR; between 2 and 15 µm) spectral range. These sources are based on chromium solid-state lasers (Cr:ZnS active crystal), and the duration of the pulses generated reaches single oscillations of the electromagnetic field (approx. 7 fs = 7∙10^-15 s). These pulses are then converted to the mid-infrared band by means of non-linear optics techniques. The laser sources we are developing have direct applications in biomedicine. In cooperation with the Ludwig Maximilians University of Munich, our lasers are applied in spectroscopic measurements of human blood for early detection of cancer. As part of the internship, we propose two topics for experimental work mainly related to optics (1) and electronics (2). If you have any questions, please email me at: maciej.kowalczyk@pwr.edu.pl

Proposed internship projects:
1. construction of a chrome pulsed laser
In this project, we will construct a chromium pulsed solid state laser from scratch. The intern will learn the process of modelling the resonant cavity of the laser and optimizing its components such as the type of pumping source, active crystal parameters etc. Different techniques for forcing the pulsed operation of the laser based on saturable real (SESAM mirror, carbon nanotubes) and artificial (Kerr lens) absorbers will be investigated. The selected saturable absorber will be optimized for pulse generation with the shortest possible duration. There is the possibility of modifying or extending this project to include research on spectral conversion of radiation using non-linear optics techniques (difference frequency generation). This research task will focus on experimental work related to optics.
2. stabilization of chromium lasers
The accuracy of spectroscopic measurement of blood samples is closely linked to the stability of the laser used, which requires that its operation is characterized by as little fluctuation as possible. In this project, we will stabilize existing chromium lasers to a so-called frequency comb. This requires precise stabilization of the laser phase and the frequency at which it generates successive pulses. The trainee will construct circuits to characterize the laser fluctuations and then carry out active laser stabilization using electronic circuits developed in our group. This research task will focus on experimental work at the interface between optics and electronics.
