Postdoc in Integrated Single-Photon Avalanche Diode Array for Quantum Computing

Introduction

Photonics is widely regarded as a key enabling technology of the 21st century. Its application across scientific and industrial domains is being accelerated by photonic integrated circuits or PICs which combine many optical components into a miniaturized chip format. Similar to electronic integrated circuits PICs are transforming areas such as healthcare communication sensing and quantum computing with the potential to create broad societal and industrial the Netherlands integrated photonics is receiving major strategic investment through the PhotonDelta National Growth Fund program. This large-scale program brings together leading companies research institutes and universities to strengthen the Dutch integrated photonics ecosystem.

Within the PhotonDelta program a nationwide consortium led by QuiX Quantum is working towards large-scale photonic quantum computing using PIC technology. As part of this mission Eindhoven University of Technology will leverage its strong III-V photonics expertise to develop high-efficiency integrated single-photon avalanche diodes or SPADs. The research will span epitaxial stack design device design fabrication and characterization in the /e cleanroom facilities. The developed SPADs will be integrated onto low-loss silicon nitride PICs to form large-scale quantum photonic processor circuits with system-level testing carried out in close collaboration with consortium partners.

Job Description

We are looking for a skilled and motivated postdoc researcher who wants to develop high-performance components for a rapidly emerging application domain: photonic quantum computing. The candidate should also be motivated to dive into technological research to develop highly manufacturable heterogeneous integration process to transfer large arrays of SPADs onto SiN wafers either through wafer bonding or micro-transfer printing.

The main task of the postdoc will be to design fabricate and validate high efficiency SPADs based on InP photonic technology. The postdoc will need to address not only the fundamental quantum efficiency of the SPAD device itself but also the interface between the SPAD and the SiN waveguide circuits. Therefore we are looking for a postdoc who can manage a relatively complex design and technology optimization problem. Besides the postdoc will work closely with mission partners such as Quix Quantum as well as other sister projects within the mission. For instance a joint development with an inverse design focused project is foreseen to realize ultralow loss III-V to SiN couplers.

You will work in the Photonic Integration group (PhI) which has about 80 members. The technology development and device realization will be supported by experienced technicians in our cleanroom facilities at /e ( You will be embedded in a Quantum PIC topical team within PhI formed by PhD and postdoc researchers from various related projects. Strong collaboration within the team is expected.

Job Requirements

• PhD degree in Physics Applied Physics Electrical Engineering or similar.
• Strong background in integrated photonics semiconductor devices and physics (preferably with experience in avalanche diodes as well as other high-performance semiconductor devices).
• Good knowledge in (numerical) modelling and component optical/electrical/thermal design.
• Experience in experimental work of which cleanroom microfabrication and chip characterization are an advantage.
• Ability to work with experts from a broad range of scientific and technology backgrounds.
• Good writing and documentation skills excellent analytical skills and communication ability.
• Ability to organize their own work independently to pursue the project-oriented goals.
