PhD Scholarship in AI-Driven Optimisation of Optical Links Based on Nano-Lasers at DTU Electro

Job Description

DTU Electro offers a PhD in AI-driven optimisation of optical links built on nano-lasers, within the Villum Investigator programme POPCOM (Power-Efficient Fiber-Optic Communication) and the DNRF Center for NanoPhotonics (NANOPHOTON). As data-centre traffic grows, energy per bit is becoming as important as spectral efficiency, and the project will use AI to jointly optimise nano-laser transmitters and their waveforms.

At a glance

• Post: PhD scholarship
• Programmes: Villum Investigator POPCOM and DNRF NANOPHOTON
• Duration: 3 years
• Apply by: 1 November 2026
• Apply: 1 November 2026 (23:59 Danish time)

What the post involves

• Develop an AI-driven optimisation framework for power-efficient signalling at maximum spectral efficiency
• Jointly optimise nano-laser transmitters, waveforms and receiver architectures
• Work on both algorithms and experimental implementation
• Explore techniques such as reinforcement learning for system design

Why this post matters

Optical links inside data centres use a growing share of the world’s electricity, so cutting energy per bit is a major goal. This PhD combines photonics hardware with AI methods, a mix that is in high demand in both research and the optical communications industry.

What DTU is looking for

• A master’s in fibre optics, laser physics, communication engineering, machine learning or a related field
• A solid background across optics, communications and ML
• Motivation, curiosity and an outgoing attitude

Nice to have

• Experience applying ML or AI optimisation to communication systems or laser modelling
• Experimental lab experience
