Descripción de la oferta de trabajo:
DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications. We are now seeking a PhD student to do research within theory and characterization of noise in optical signal processing using integrated photonic circuitry. The Research will be carried out within the centre of excellence: “Silicon Photonics for Optical Communications,” (SPOC) funded by the Danish National Research Foundation. Starting date in the fall 2017. Responsibilities and tasks The goal of the PhD project is to do research on the impact of noise in optical signal processing using nonlinear integrated circuits and investigate the tradeoffs between possible nonlinear materials. In future optical communication systems, such circuitry may have a wide range of applications including frequency comb generation and wavelength conversion, in classical photonics as well as in quantum photonics. The research will focus on theoretical modelling and comparing to optical measurements. The modelling will include various effects including Raman scattering, intensity dependent refractive index and multi-photon absorption. In addition, the analysis will include the impact of exciting multiple spatial modes in the considered waveguides in e.g. couplers. A starting point of the PhD project will be to develop a theoretical understanding of spontaneous emission in four-wave-mixing and Raman scattering processes. The goal of the PhD project is to be able to compare different material options (not necessarily silicon-based) based on their different nonlinear figure-of-merits and noise properties. The PhD project will have strong synergies to other activities within the SPOC centre on e.g. design and fabrication of nonlinear waveguides, characterization of frequency combs, nonlinear effects in optical fibers, and quantum information. It is expected that the PhD student will benefit from collaboration with these activities to enhance the outcome of the PhD project. Qualifications Candidates should have a master's degree in engineering/Physics or a similar degree with an academic level equivalent to the master's degree in engineering/Physics. Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. Assessment The assessment of the applicants will be made by Professor Karsten Rottwitt, Senior Researcher Lars H. Frandsen and Associate Professor Michael Galili. We offer We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and appointment terms The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.
