This PhD project focuses on developing integrated quantum light sources that generate entangled or correlated photons for emerging quantum networking, sensing and computing technologies. Based at the University of Strathclyde and supported by the Fraunhofer Centre for Applied Photonics (CAP), you will work at the intersection of experimental physics and real-world engineering, contributing to integrated optical sources with genuine routes toward deployment.

You will investigate platforms that exploit nonlinear optical processes to create tailored quantum states of light. These sources will be designed to achieve high pair-generation rates, narrow bandwidths suitable for interfacing with quantum memories, and robust, stable operation suitable for field applications.

The work is primarily experimental, involving photonic devices and advanced optical measurement platforms. You will design and assemble optical testbeds, interface with fabricated chips, and characterise quantum correlations, heralding efficiencies and photon interference. There will also be room to develop models of nonlinear processes, dispersion engineering and device performance. As the project progresses, you may explore areas such as spectral shaping, quantum frequency conversion, or linking sources to external platforms including quantum memories or early-stage network demonstrators.

You will join a collaborative and supportive research environment with the freedom to influence the direction of your work while contributing to broader group activity in quantum photonics. Through Fraunhofer CAP, you will engage with industrial partners developing quantum key distribution hardware, network infrastructure and space-qualified optical systems. These connections ensure exposure to real-world constraints including footprint, environmental stability, manufacturability and telecoms compatibility, while keeping your research aligned with practical needs.

This opportunity suits a student who enjoys hands-on optical experimentation and wants to help move quantum photonics from the lab towards deployment. Experience with lasers, integrated optics or quantum measurements is helpful but not essential. Curiosity, precision and enthusiasm for solving experimental challenges are what matter most.
