PhD in cryogenic silicon-photonics-based optical interconnects for quantum computer

Introduction

Quantum computers require a large bandwidth of classical data to control and read out the qubits. Since such computers are often placed in a cryostat copper cables are increasingly unfeasible. We know datacenters work with optical interconnects based on integrated photonics. Can we also use these as cryogenic transceivers Explore with our partner NXP how we can realize silicon-photonics based transceivers in their semiconductor processes.

Job Description

As a PhD student in our group you will be responsible for developing silicon-photonic based optical transceivers that can work at cryogenic temperatures of about 4 K. We will work closely with our partner NXP on their ion-based quantum computer. Our approach will be to design the transceiver in one of NXPs mature processes currently being used for single-photon avalanche photodiodes (SPADs) and electronics. Using a zero-change approach we will design novel high-speed photodetectors waveguides and modulators into this platform adding to their process design kit (PDK).

In practice this means that you will be working closely with the integrated photonics experts in our group and with the electronics and process experts of NXP. You will explore how we can best realize photonic components into this NXP fabrication process. This means you will effectively have to establish a new technology platform. Are you up to that task You will need to develop in-depth knowledge on integrated photonics gain familiarity with the mature silicon processes and design tools and above all leverage your creativity to design all this.

So where is the scientific challenge in all this Well first of all we need to establish the best type of transceiver for the application. What architecture will work best Secondly novel components most notably high-speed photodetectors and modulators need to be developed. And finally a bit of semiconductor physics: will this all still work at 4K You will work on simulations with commercial and in-house tools design in a mature PDK and test and characterize the final chips in our well-equipped lab.

As a PhD student you will be part of a dynamic and ambitious environment with plenty of opportunities to develop yourself. Our newly established Casimir Institute - Eindhoven University of Technology (TU/e) consists of many closely-cooperating research groups focusing on integrated photonics semiconductor technology and quantum technology. You will be part of the Photonic Integration group (PhI) at Electrical Engineering which has about 70 members 25 of which are PhD students. Our laboratory facilities are extensive and state of the art. Our city Eindhoven is located in the heart of the leading semiconductor and photonics ecosystem Brainport close collaboration with a wider range of academic and industrial partners can also be anticipated.

Job Requirements

• Masters degree in Physics Electrical Engineering or similar;
• Affinity with photonic or electronic devices and circuits;
