PhD candidate on Laser-assisted manipulation for coupling and assembly of photonic chips

Netherlands

Closing soon

We are looking for a PhD-candidate to strengthen our highly motivated and multi­disciplinary research team, who will work on laser-assisted techniques to manipulate optical elements on a microscopic scale, helping in the assembly of photonic chips, in the framework of a large Dutch project, titled ‘Groeifonds NXTGEN HIGHTECH'. This latter project is targeting groundbreaking developments in next generation high-tech equipment, to support growth and development of important Dutch high-tech sectors. Within the projects, knowledge institutes cooperate with relevant industry on novel solutions for societal challenges.

The Background

Coupling light from optical fibres to integrated waveguides, as well as coupling light from optical chip to optical chip, is a challenge in the mass- production of photonic integrated circuitry. In the project, laser-assisted methods are developed to assist techniques that facilitate fibre-to-chip and chip-to-chip communication.

For an example of our work in the field of laser-assisted manipulation, please refer to: Folkersma, G. , Römer, G. R. B. E. , Brouwer, D. M. , & Herder, J. L. (2016). High precision optical fiber alignment using tube laser bending. International journal of advanced manufacturing technology, 86(1), 953-961.High Precision

Your Challenge

Photonic chips are essential for modern telecommunication, sensing or computing, and integration of those systems is a key factor in making these systems more affordable and portable. While the fabrication of photonic integrated chips advances rapidly, the interface between these chips and fibre optics or free-space optic is still limiting the cost and efficiency of these systems. We expect that laser-based methods can greatly increase speed and reliability of assembly of these photonic systems. Laser-based manipulation can help in trimming components to be accurately aligned with sub-micron precision. In this project, we are looking at the interaction between the ultrashort laser pulses and the materials of the photonic materials used in order to manipulate coupling elements such as micro-mirrors to achieve these optical connections.

You will work with pulsed laser systems to manipulate optical elements on a microscopic scale, helping in assembly of photonic chips. The interaction of laser light and optical materials will be studied and the gained knowledge is used to suggest specific processes that can be used in the production of new generation photonic circuits. For this project, you will work in the labs of the Chair of Laser Processing on a ultrashort pulsed laser system for manipulation of photonic materials. You will perform optical measurements and analyze the modified material with the help of microscopic and other methods.

You will closely collaborate with researchers in other groups at the University of Twente and the industrial partners in the project. You will also have access to the renowned research facilities of the University of Twente.

If you are someone with a strong background in laser-material processing, preferably in ultra-short pulsed laser-material processing, driven by curiosity, creativity, and dedication, we invite you to apply for this opportunity.
