PhD in ‘Scalable Neuromorphic Photonic Circuits and Interconnects’
Contract: Full Time/Fixed Term

The Semiconductor and Photonics Education and Research (SPEAR) Centre, funded by PEACEPLUS and managed by the Special EU Programmes Body (SEUPB), is an €8.5 million cross-border project by Atlantic Technological University, Ulster University, Tyndall National Institute and their associate partner Seagate Technology. The Centre aims to build research capacity in integrated photonics and semiconductor technologies, contributing to the development of Ireland’s and Northern Ireland’s deep-tech innovation ecosystem. It seeks to train the next generation of scientists and engineers to support growth in sectors such as healthcare, telecommunications, advanced manufacturing, and sensor networks. The position is available at Tyndall National Institute in Cork.

Project Description
Emerging neuromorphic photonic systems aim to combine the massive parallelism of neural networks with the ultra-high bandwidth and low latency of integrated photonics. By performing computation and information transfer directly in the optical domain, these systems have the potential to deliver real-time signal processing and artificial intelligence at far lower energy cost than today’s electronic processors. To realise this potential, new system-level architectures are needed that remain stable and accurate despite fabrication variability, thermal drift, and device ageing.

This PhD project will focus on the design and fabrication of neuromorphic photonic circuits that integrate computation and communication on a single platform. The research will develop physics-based models of photonic neurons and interconnect fabrics, using realistic component parameters and co-simulation with electronic control circuitry.

A key innovation is the development of adaptive calibration and reconfiguration mechanisms that allow photonic networks to detect performance drift or device faults and dynamically restore correct functionality during operation. The student will collaborate with partners in the SPEAR consortium to design runtime monitoring and control algorithms that enhance the yield, stability, and resilience of large-scale neuromorphic photonic systems.
This project will involve simulation, design and fabrication leading to final experimental demonstrators in collaboration with team members within the Photonic Systems Group at Tyndall.

Key Responsibilities

Develop and validate compact models for neuromorphic photonic building blocks (microring and MZI weight banks, phase shifters, SOAs, etc.).
Design WDM-based photonic interconnects for neuromorphic architectures and assess their energy, latency, and fault tolerance.
Develop adaptive control and calibration algorithms
Perform co-simulation of photonic and electronic subsystems (e.g. using Python, Lumerical/Luceda, or VPI).
Present research findings at key conferences and publish in high-impact journals.
Complete required PhD coursework, participate in group meetings, and contribute to outreach activities.

Essential Criteria

First or upper second-class honours degree (or equivalent international qualification) in Physics or Electronic Engineering.
Strong interest in neuromorphic or AI hardware architectures.
Excellent analytical and programming skills (Python, MATLAB, or equivalent).
Ability to work in a self-sufficient manner and as part of a multidisciplinary research team.
Proficiency in written and spoken English.

Desirable Criteria

Masters degree in Physics/Engineering/Photonics
Experience with photonic circuit simulation tools (e.g. Lumerical INTERCONNECT, Luceda IPKISS, VPI Photonics, or others).
Familiarity with mixed-signal or FPGA-based control systems.
Knowledge of machine learning frameworks (e.g. PyTorch or TensorFlow).
Prior research experience in integrated photonics or neuromorphic systems.
