1 PhD Research position in Ferroelectric Photonics in Sweden | KTH - Royal Institute Of Technology

The PhD project shall develop research across the fields of ferroelectric and photonic sciences. It aims at studying the fundamental physics of interactions between the spontaneous polarization of ferroelectric materials and light in classical and quantum regimes, exploring their implications for frequency conversion and information processing. As a model system ferroelectric materials of the lithium niobate (LiNbO3) family shall be used, where the convergence of ferroelectric science and optics has been pushed the furthest towards practical devices. Specific goals of the project are:

• to advance the fundamental understanding and control over ferroelectric domain switching (poling) at local scales in LiNbO3 and LiTaO3 substrates;
• to investigate the interaction dynamics and coherence properties of parametric processes in periodically poled crystals;
• to design, fabricate and test proof-of-principle device demonstrators for coherent optical parametric generation and amplification.

The employment is four years with a possibility of extension up to a maximum of five years. Up to 20 percent department duties may be included in the employment.

Qualifications:

A suitable background for this position would be a Master of Science in Physics or Electrical Engineering, preferably with a specialization in photonics, optoelectronics or ferroelectric material science. Competence in nonlinear optics and nanotechnology is highly desirable. Cleanroom expertise and experimental work in optics and/or electronics constitute further merits for the position. In addition to the traditional academic merits, a relevant degree project, international experience and language skills are regarded as advantageous qualifications.

Applicants must be strongly motivated for doctoral studies, possess the ability to work independently and perform critical analysis as well as possess good cooperation and communication skills, suitable for work in an international research environment.
