About this position
The LUMIRing project at ISCTE - University Institute of Lisbon is recruiting a Postdoctoral Researcher to work on multicore fiber sensing and communications in the Multicore Fiber Integration of Sensing and Communication (MFISAC) project.
This opportunity is centered on a live optical fiber testbed, the Lisbon Underground Multicore Fiber Ring (LUMIRing), deployed in Lisbon Metro’s Yellow Line. The platform is designed to investigate weakly coupled multicore fiber transmission under realistic underground conditions, including the mechanical stresses and deployment challenges found in metro infrastructure. The role offers the chance to contribute to advanced research at the intersection of optical communications, fiber sensing, and multicore fiber technology.
The project includes a substantial test-bed infrastructure: a 12-tube cable with 12 fibers per tube, 74 standard-cladding weakly coupled multicore fibers of several types, and 70 conventional single-mode single-core fibers. The research environment is highly collaborative, bringing together partners from Portugal, Germany, Italy, and the USA, including metro operators, fiber and cable manufacturers, telecom providers, optical component suppliers, and a telecommunications research institute.
The successful candidate is expected to help design, implement, and validate techniques that reduce performance degradation and support the integration of data transmission with sensing. The position is especially relevant for researchers interested in optical systems, transmission performance, network behavior under real-world conditions, and practical innovation in next-generation telecom infrastructure.
Eligibility highlights: a PhD or equivalent in Telecommunications Engineering or Optics is required. Prior experience in optical communications, especially multicore fiber technology, is preferred. Strong English proficiency is required, and all application materials must be submitted in English.
Funding and appointment: the post is a 19-month full-time employment contract with Iscte-IUL, with an annual gross salary of 65,000 euro and standard public-sector benefits.
How to apply: email your application to [email protected]. Include a CV, a personal motivation letter (up to one page), official graduate and postgraduate transcripts, and contact details for your PhD advisor or employer. The deadline is 31 October 2026.
