This PhD project focuses on spatiotemporal integrated metamaterials for nonreciprocal photonics . The successful candidate will design dynamically modulated, chip-scale metamaterials that enable nonreciprocal light control, with applications in photonic circuits for optical communication and quantum technologies. The work combines theoretical and numerical design of time-varying structures, on-chip fabrication using advanced nanolithography, and experimental demonstration of nonreciprocal light transport. The project is positioned at the intersection of photonics, optics, and nanofabrication, and aims to translate dynamically modulated metamaterials into integrated photonic devices. The PhD candidate will be based in the Photonic Integration group in the Department of Electrical Engineering at Eindhoven University of Technology . The project is part of the SPARK Marie Skłodowska-Curie Doctoral Network , offering collaboration with a multidisciplinary, international consortium working on related nonreciprocal and photonic integration technologies. Collaboration is an important part of the research environment. The candidate will work closely with researchers across design, fabrication, and characterization, and will also spend time at partner institutes in Portugal for component measurements and chip-level integration. The position is co-supervised by Prof. M. Piccardo at INESC MN , strengthening the cross-institutional and applied research dimension of the project. The wider TU/e environment is strongly connected to Brainport Eindhoven and its high-tech ecosystem, with a focus on electrical engineering, photonics, and advanced manufacturing. This setting provides a hands-on, application-oriented research culture with access to technical infrastructure and an international academic network.

PhD opportunity at Eindhoven University of Technology in dynamic metasurfaces for spacetime-engineered light. This fully funded PhD position sits within the Photonic Integration group in the Department of Electrical Engineering at Eindhoven University of Technology (TU/e), in the Netherlands. The project is part of the SPARK Marie Skłodowska-Curie Doctoral Network and focuses on developing metasurfaces for synthetic crystal rotation and nonreciprocal light-matter interactions through ultrafast spatiotemporal modulation. The research combines theoretical modelling, numerical simulation, device realization, and ultrafast experimental characterisation. The successful candidate will study anisotropic metasurfaces with epsilon-near-zero-like behaviour, develop dynamically modulated metasurface structures, and evaluate their optical response with the aim of demonstrating synthetic spacetime rotation and generating spatiotemporal light fields. The work is positioned at the intersection of photonics, optics, applied physics, and advanced materials research. The PhD candidate will work in an interdisciplinary, international environment and collaborate closely with researchers across theory, fabrication, and characterisation. The project includes secondments at the University of Navarra (UPNA), Spain, for theoretical modelling, and at UltraFast Innovations GmbH (UFI), Germany, for ultrafast optical characterisation. These secondments provide access to complementary expertise and facilities within the consortium. Eligibility highlights include a Master's degree in Electrical Engineering, Optics, Applied Physics, Materials Engineering, or a related field; a research-oriented mindset; strong teamwork and communication skills; interest in industrial collaboration; and fluent English at C1 level. The appointment is full-time for four years with an intermediate assessment after nine months. Funding and benefits are provided under the Dutch Universities collective labour agreement (scale P), with a gross base salary of approximately €3,204 to €4,051 per month, plus an 8% holiday allowance and an 8.3% year-end bonus. Additional employment benefits include pension, leave provisions, training support, commuting/home-work allowances, and access to TU/e facilities and support services. The application deadline is 2026-10-18. Applications must be submitted online and should include a cover letter, CV with research experience and publications, and contact details for three references.

This postdoctoral position at Eindhoven University of Technology focuses on the development of advanced inverse design procedures for improved chip quality in photonic quantum computing. Photonic integrated circuits (PICs) are revolutionizing fields such as healthcare, communication, sensing, and quantum computing, and the Netherlands is investing heavily in integrated photonics through the PhotonDelta National Growth Fund program. The project is part of a nationwide consortium led by QuiX Quantum, aiming to scale photonic quantum computing using PIC technology. The main research challenge is to achieve high fabrication yield and maintain circuit performance despite process variations in large-scale manufacturing. As photonic quantum processors become more complex, even minor fabrication imperfections can degrade performance. The project addresses these challenges by developing tolerance-aware inverse-design methodologies for photonic quantum computing building blocks. The research combines computational photonic design, manufacturability optimization, and system-level validation to create robust photonic components such as beam splitters, couplers, and interferometric structures. Realistic fabrication constraints, including etch-depth variations, line-edge roughness, and dimensional deviations, are incorporated directly into the optimization process. The project will also establish robust libraries of manufacturable photonic components and validate them through collaboration with foundry partners. The successful candidate will join the Photonic Integration (PhI) group at TU/e, which comprises over 90 researchers working on cutting-edge integrated photonics technologies. The postdoc will be embedded in a multidisciplinary quantum photonics team, collaborating with PhD students, postdocs, and senior researchers. The project benefits from strong industrial and academic partnerships within the PhotonDelta ecosystem and access to advanced cleanroom facilities at NanoLab@TU/e, as well as external foundry platforms. Applicants must hold a PhD in Physics, Applied Physics, Electrical Engineering, or a related field, with a strong background in integrated photonics, semiconductor devices, and physics. Experience in design, numerical modeling, component design, and experimental work (especially cleanroom microfabrication and chip characterization) is highly valued. Candidates should demonstrate excellent analytical, communication, and documentation skills, and be able to work independently and collaboratively in a multidisciplinary environment. Employment is full-time for 2 years, with a competitive salary (scale 10: €4,241–€5,538), year-end bonus, vacation pay, and allowances for commuting, working from home, and internet costs. Additional benefits include access to high-quality training programs, technical infrastructure, on-campus childcare and sports facilities, partially paid parental leave, and support for international candidates (tax compensation scheme and moving expenses). The TU/e Postdoc Association offers tailored support, training, and networking opportunities. To apply, submit a complete application online, including a cover letter, CV, and contact information for three references. Applications will be screened promptly, and the vacancy remains open until filled. For further information, contact Associate Professor Humeyra Caglayan ([email protected]) or [email protected]. The position is based in Eindhoven, Netherlands, within the vibrant Brainport tech region.
