JOB OFFER for PhD student
Position in the project: PhD student
Scientific discipline: Physics
Job type (employment contract/stipend): Stipend
Number of job offers: 1
Remuneration/stipend amount/month 3500 PLN (full remuneration cost – brutto)
Position starts on: 4.01.2021
Maximum  period of contract/stipend agreement: 4 months
Institution: Warsaw University of Technology, Faculty of Physics
Project leader: dr inż. Krzysztof Switkowski
Project title:

 

Terahertz structured beams for material diagnostics and microscopy

Project is carried out within the  HOMING 5/2018 programme of the Foundation for Polish Science

Project description: The project responds, to the need of screening potential security threats concealed by airline passengers, or in parcels for embassies, the topic nowadays essential. The project aims at improvement of focusing of terahertz radiation. According to classical electromagnetics for Gaussian beams, the focus spot diameter cannot be smaller than c.a. the beam wavelength due to the diffraction limit. The effect is notably for long terahertz wavelengths and large spot diameter hinders resolution of terahertz imaging scanners. The recent experiments in the so-called structured light show that the limit is less constrained thereby structured beams are promising in improvement of terahertz imaging. The project coalesces two very vibrant fields in photonics: structured light and terahertz techniques. It is predominantly experimental research, pioneering in THz vortices generation and their characterization. The outcome of the project will improve detail resolution in terahertz security scanners and material diagnostics, i.e., terahertz microscopy for semiconductor and material science.
Key responsibilities include: In scope of the PhD research a candidate will be responsible for:

1.        Design and making prototypes of optical set-ups (i.e. Terahertz Time-Domain spectroscopic set-ups and terahertz spatial intensity and phase profilers).

2.        Performing experimental research in the field of terahertz techniques with an emphasis on THz generation/detection schemes based on femtosecond lasers.

3.        Design of Terahertz phase elements

4.        Terahertz beam propagation simulations (i.e. in Comsol) .

5.        LabVIEW programming of experiments

6.        Experimental data analysis and scientific writing papers

Profile of candidates/requirements: 1.        MSc (or equivalent degree) in physics, electrical and computer engineering,  material science or related disciplines.

2.        Outstanding academic records

3.        General engineering skills

4.        Fluent English (spoken as well as good writing skills).

Required documents: 1.        CV

2.        Cover letter

3.        List of publications

We offer: The experimental work will be performed in well-equipped Femtosecond Techniques Laboratory at Faculty of Physics at Warsaw University of Technology. We offer mentoring in experimental optics, terahertz techniques as well as ultrafast laser physics. In initial part of the project we are planning practical trainings in scope of cutting-edge technologies such as terahertz techniques, structured light and singular optics to name a few.
