DTU Fotonik works with all areas of photonics engineering, including a strong focus on optical communications. We are hereby announcing an open Post doc position within generation and processing of entangled states in multimode optical fibers by four wave mixing. The project is part of the centre of excellence “Silicon Photonics for Optical Communications” (SPOC) funded by the Danish National Research Foundation, which was established in 2015 with a funding period of 10 years. The SPOC centre was established with the aim to significantly advance the state-of-the-art in ultra-high capacity optical communications and this project will be at the heart of this activity.

Responsibilities and qualifications
The task of the post doc is to research handling and manipulating of optical quantum states for example single photon quantum states without destroying the quantum state. Examples of research could be to: investigate the possibility of employing time lens units capable of manipulating e.g. hi-D frequency-entangled states, to convert quantum states between frequency- and time domain, to demonstrate novel characterization and applications of high dimensional quantum states. We have ongoing activities related to the control of multiple modes in fibre for intermodal four-wave mixing, which can create entangled photon-pairs in the visible and in the C-band, which may be useful to interface to solid-state memory units. The research of the post doc is expected to be mainly theoretically focused, but with a strong interaction with experimental projects having strong synergy to the post doc position.  


As a formal qualification, you must hold a PhD degree (or equivalent). Prior theoretical knowledge of multimode optical fibers and intermodal nonlinear fiber optics as well as quantum optics, preferably in optical fibers, is an advantage but all candidates with a strong background, theoretical or experimental, in one or more of the before mentioned topics are encouraged to apply.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.The period of employment is 2.5 years.

The place of work is DTU Fotonik, Ørsteds Plads, Building 343, DK-2800 Kongens Lyngby, Denmark.
