Project Overview

DC14 will focus on the design and implementation of thermoelectric cooling solutions for active thermal management of photonic integrated circuits within the MGICIAN Doctoral Network.

The project will address precise temperature control requirements to ensure wavelength stability, signal integrity, and long-term reliability in chip-scale photonic platforms. The research will target compact cooling architectures, efficient heat extraction, and compatibility with integrated device structures.

The project will combine thermal simulations, device-level modelling, and experimental validation to establish cooling-device-performance relationships and ensure scalable integration of magnesium-based thermoelectric modules into advanced optoelectronic systems.

Research Tasks and Training Objectives

The Doctoral Candidate (m/f/div) will:

  • Define thermal management requirements and performance targets for photonic integrated circuits
