Several PhD positions are available at the Integrated Optical Systems group of the University of Twente, part of the Optical Sciences chair and associated to the MESA+ Institute for Nanotechnology. The PhD students will become part of a team working on the development of low-loss sputtered materials for Integrated Photonics. In particular, low-loss high-gain rare-earth ion doped aluminium oxide waveguide amplifiers and lasers integrated onto a passive silicon nitride platform will be developed for operation in the C-band and at around 2 mm. Operation down to the UV wavelength range will also be investigated. Devices that will be developed include laser sources for time-of-flight and FMCW LiDAR, on-chip femtosecond lasers and high power on-chip amplifiers. Other sputtered materials will also be studied for the realization of high-speed modulators and on-chip optical isolators.

The projects comprise modelling of the devices, the development of the fabrication process in the MESA+ Nanolab cleanroom facility, which has all necessary state-of-the-art microfabrication equipment required to carry out this work, and optical characterization in the facilities of the research group.

The projects will leverage our expertise in the development of sputtered optical materials for integrated photonics consolidating our international position in this field. The projects are carried out in collaboration with industrial partners in the framework of two European projects and one national Dutch project.


We are looking for candidates with a MSc degree in engineering physics, electrical engineering, materials engineering/science or photonics engineering, with a good background in cleanroom microfabrication, deposition of optical materials and design/simulation of optical devices. Experimental experience in the optical characterization of integrated optical devices is desirable.

Suitable candidates can operate in a multidisciplinary multicultural team, have proficient oral and written English language skills, and are capable of scientific communication, also towards non-expert partners. Excellent soft communication skills at all levels are required. Female candidates and members of minority groups are equally encouraged to apply as we strive for working in a well-balanced inclusive team.


We offer a challenging fulltime position in an inspiring multidisciplinary and international environment. The university offers a dynamic ecosystem with enthusiastic colleagues in which internationalization and inclusion are an important part of the strategic agenda.


  • We offer you a four-year full-time position
  • We provide excellent mentorship in an inspiring research environment, with state-of-the art research facilities.
  • Professional and personal development programs
  • Gross salary ranging from € 2395 to € 3061 (4th yr) per month
  • Holiday allowance (8%), end-of-year bonus (8.3%)
  • Good secondary conditions
  • A green Campus with lots of sports facilities.


Please send your application before 31th of December including:

• A specific description of why you want to apply for one of the PhD positions and why you are a good match for the team – please do not send general application letters.
• A detailed CV (resume) with publication list
• An academic transcript of BSc and MSc education
• A high TOEFL score (> 90 or 100) or IELTS score (> 6.5 or 7) is generally required.

For detailed questions, please contact Prof. dr. Sonia M. Garcia-Blanco (s.m.garciablanco@utwente.nl).


The Integrated Optical Systems group consists in average of 4-5 PhD students, 2-3 MSc students, 1-2 post-docs and several staff members. Our vision is to develop novel materials, devices and integration technologies for Integrated Photonics to solve societal problems. We are part of the Optical Sciences chair, which provides a dynamic and social environment for the daily work of the team. We are part of the MESA+ Institute for Nanotechnology, which offers advanced characterization and fabrication tools at the nanoscale, as well as a stimulating scientific environment with more than 250 PhD students working on various aspects of nanoscience and technology.

In addition, we are part of a group of around 80 researchers that explore, within the research cluster Applied Nanophotonics (ANP), multiple aspects of modern photonics. These include technologies such as the development of materials, integration technologies, photonic assembly, packaging, and laser processing for applications including quantum optics, control of light scattering, photonics crystals, XUV optics, biomedical imaging, and sensing.


TNW Faculty (Faculty of Science & Technology)

The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.

As an employer, the TNW Faculty offers jobs that matter. We equip you as a staff member to shape new opportunities both for yourself and for our society. With our Faculty, you will be part of a leading tech university that is changing our world for the better. We offer an open, inclusive and entrepreneurial climate, in which we encourage you to make healthy choices, for example, with our flexible, customisable conditions.

University of Twente (UT)

University of Twente (UT) has entered the new decade with an ambitious, new vision, mission and strategy. As ‘the ultimate people-first university of technology’ we are rapidly expanding on our High Tech Human Touch philosophy and the unique role it affords us in society. Everything we do is aimed at maximum impact on people, society and connections through the sustainable utilisation of science and technology. We want to contribute to the development of a fair, digital and sustainable society through our open, inclusive and entrepreneurial attitude. This attitude permeates everything we do and is present in every one of UT’s departments and faculties. Building on our rich legacy in merging technical and social sciences, we focus on five distinguishing research domains: Improving healthcare by personalised technologies; Creating intelligent manufacturing systems; Shaping our world with smart materials; Engineering our digital society; and Engineering for a resilient world.PHD POSITION “OPHELLIA FEMTOCHIP ASINDO”
