What are the responsibilities and job description for the Fiber Sensing PostDoc position at NOKIA?
This is a disruptive, hands-on research role focused on tackling fundamental scientific and conceptual problems in fiber-optic communication and advanced fiber sensing.
You will be responsible for inventing and implementing photonic subsystems with particular focus on developing components and signal processing techniques for optical communication and fiber sensing applications. The work will involve both proof-of-principle studies in a lab environment and field trials of developed prototypes, showcasing performance in real-world scenarios. You are expected to collaborate extensively, both within Nokia Bell Labs and with external partners.
As a research scientist, you will be expected to make fundamental contributions in one or multiple of the following areas:
Portable ultra-stable lasers: Design, conduct, and lead research projects investigating the optimization of ultra-narrow bandwidth laser systems and derived optical comb systems, including the fabrication, design, and packaging of related devices using state-of-the-art technologies. Demonstrate applications of ultra-stable lasers and combs for fiber sensing, time synchronization, and the stabilization of quantum communication links.
Advanced Real-Time DSP Development: Propose and investigate experimentally optimized coherent modulation formats for reflective fiber sensing interrogators. Contribute to real-time implementation of coherent transmission, fiber link stabilization, and fiber sensing systems using both FPGAs and GPUs. The major emphasis is on developing DSP schemes that minimize any penalty on coexisting coherent optical transceivers and facilitate integrating fiber sensing and optical metrology techniques into live networks.
Real-time Event Identification and Analysis: Develop and implement novel machine learning (ML) algorithms specifically tailored for long-distance reflective fiber-sensing systems. A particular emphasis is on real-time ML implementations, combing edge and cloud compute to combine streams from several field systems. Model development includes both developing foundational models and domain-specific model adaptation.
You are expected to publish results in top-tier optical conferences and journals.
To excel in this role, you should possess a potent blend of research excellence, experimental experience, technical depth, and programming proficiency.
