Leader in Integrated ICT Hardware & Systems

Researcher - Silicon Photonics

BC-59  Researcher (Silicon Photonics)

Contract: Full Time/Fixed Term - Full time – 3 years

We seek a postdoctoral researcher to design, build and demonstrate photonic circuits based on the heterogeneous integration of GaAs/InP materials onto silicon photonics platforms.

Silicon based photonics has emerged as the means by which the functional power of photonics (high bandwidth, wavelength division multiplexing, parallelism) can be crystallised and made into circuits akin to electronics. The crux is to integrate active elements (lasers, modulators, detectors, isolators etc) in a seamless manner. We think that the technique of transfer printing where materials and devices are engineered on one substrate before being transferred to the silicon with precise placement will be the key enabler for the mass production of such circuits.

The project is in collaboration with companies and with other teams at Tyndall. The project is part funded by Science Foundation Ireland.

Key Responsibilities

  • Develop III-V (InP, GaAs and related materials) semiconductor device design (simulation), silicon circuit design, realisation of the devices (growth, fabrication), integration using transfer printing followed by measurement and evaluation of the performance of the devices and circuits.
  • Development specific clean room process flows to realise the devices and circuits.
  • Analysis and Report the results including the preparation of project deliverables, publications and the delivery of prototypes, as well as providing direct technical support to other group members using their knowledge and outputs.
  • Disseminate the outcomes of the research to the group, including peer‐reviewed academic publications and presentations at Tyndall and at conferences of international standing.
  • To engage in appropriate training and professional development opportunities as required by the Principal Investigator, School or College in order to develop research skills and competencies.
  • To co-supervise postgraduate research students who are studying for a Masters or a PhD and have an agreed role in supporting these students in their day to day research.
  • To perform other related duties incidental to the work described.
  • Participate in Education and Public Engagement activities, as required.
  • Contribute to the engagement on intellectual property activities in partnership with the Office of Technology Transfer
  • Ensure all activities are compliant with the Tyndall Quality Management system.
  • Ensure all activities are compliant with the required Health and Safety standards.
  • Carry out any additional duties as may reasonably be required within the general scope and level of the post.

Essential Criteria

The successful candidate must have a PhD in physics, electrical engineering, material science or a related field or demonstrated equivalent experience. The person must have a comprehensive understanding of semiconductor device physics as appropriate for advanced photonic devices. The candidate must have experience in modelling and measurements of waveguides, of measurement of semiconductor lasers. The person should be familiar with the fabrication of semiconductor devices in a clean room environment. The candidate must show initiative, teamwork with excellent writing and communication skills.  

Desirable Criteria

  • Relevant experience in the design of devices/circuits, the characterisation of photonic devices and knowledge of transfer printing is a distinct advantage. A strong publication record is desirable.
