(2D BN) and the potential of this material for use in modelocking
techniques and the generation of ultrashort laser
pulses in integrated devices. The studies will cover key
phenomena and parameters of nonlinear optics and UV
luminescence in 2D BN, such as nonlinear absorption, gain
bandwidth, and fluorescence lifetimes. The Project
comprises two parallel work packages: the first focuses on
the growth and characterization of 2D BN
heterostructures, while the second concentrates on
nonlinear optics research and mode-locked cavities.
The Project will be conducted over 48 months by two
research teams: the Layered Materials Laboratory of the
University of Warsaw (Faculty of Physics) and the Laser
Center Group of the Institute of Physical Chemistry, Polish
Academy of Sciences (PAN). Expected outcomes include
the development of new growth protocols for 2D BN
heterostructures with enhanced nonlinear properties and
well-defined UV luminescence characteristics, which would unlock new directions in the field of ultrafast
integrated lasers, with potential future applications in e.g.
nonlinear imaging.
The successful candidate will be joining inter-institution
research team focused on delivering two-dimensional
boron nitride heterostructures (2D BN) for small formfactor
ultrafast lasers. The candidate will be expected to
spearhead efforts in versatile characterization of
nonlinear response of 2D BN developed in different
technological approaches. The parameter space of
interest encompasses among others nonlinear

- building and operating experimental setups for
nonlinear response characterization of 2D BN
heterostructures;
- fully focusing on the experimental characterization
section and on running the experiments with the
structures investigated in the project;
- closely collaborating with the Project PI and the other
team members, including the heterostructure growers
from University of Warsaw;
- participating in manuscript preparation
communicating the obtained results;
- contribution to the efficient functioning of the Laser
Center Group lab;
- scientific initiative and contribution through regular
reporting and publishing, as well as presenting at group
meetings, national and international conferences

We offer a post-doctoral position (full-time employment)
in the Institute of Physical Chemistry PAS with a gross
salary of Around 9.650,00 PLN gross
per month financed from the NCN OPUS 26 Project no.
2023/51/B/ST7/01204 entitled “Two-dimensional boron
nitride: a game-changer for ultrafast lasers in portable
applications?”
100% of the work time of Postdoc will be devoted to the
realization of the proposed project. The offer is for 6
months with a possible extension up 45 months

The successful candidate will benefit in the form of new
knowledge and methods. The Project deals with advanced
methods in nonlinear and ultrafast optics experimentation
as well as in the technology and characterization of unique
two-dimensional van der Walls crystalline materials – with
direct access to both the required experimentation
apparatus and the technological facilities. For this reason
wide range of candidate profiles are expected to benefit
from gaining new knowledge skills during the Project’s
implementation.
The results of the research will be submitted to high
impact factor journals, and the Project funding is also
secured for covering the cost of participation at
international conferences for communicating the results.
The successful candidate will be eligible for all programs
at the IPC PAS, including the IPC PAS Young Scientists
competition and the IPC PAS Young Scientists Mobility
competition.
Institute provides an opportunity to participate in
ERASMUS+ programme.

1. Ph.D. degree in Physics or a closely related field obtained in
the year of employment in the project or within 7 years
before 1 January of the year of employment in the project,
and no later than the start date of employment in the
project. For researchers with multiple PhDs, the date of the
first PhD award is deemed the reference date. The
extension might apply according to the National Science
Centre, Poland, rules.
2. Publication record and research experience;
3. Ability to work independently as well as in a group;

4. Achievements in instruments development and
construction (laser cavities, nonlinear and ultrafast
optics characterization) are welcomed and expected;
5. Familiarity with a computational or programming
language (e.g. matlab, python, lab view) will be
considered an advantage;
6. Ability to communicate fluently in English (written and
spoken);
7. Strong motivation to work and pursue scientific
questions with creativity, unconstrained creativity and
analytical thinking;
8. Generally, experience in instrument development,
especially from scratch, would be a plus. Solid
experience in troubleshooting optics and photonics
problems and excellent communication skills in English
are necessary.
