Tyndall National Institute
Lee Maltings, Dyke Parade, Cork
PT-29 Researcher in High Speed Optoelectronic Devices for Access Networks
Contract: Full Time/Fixed Term
Tyndall National Institute at University College, Cork invites applications for a Postdoctoral Researcher in the area of high-speed optoelectronic device development for next generation passive optical access networks. A primary area of focus will be low cost tunable lasers and associated wavelength control schemes. The position is available immediately and is funded by Science Foundation Ireland for a period of up to two years initially.
The successful application will join the Photonic Systems Group (PSG), at the Tyndall National Institute, which is an established team (approximately 25 people) comprising photonic communication system and device experts.
The Researcher will work on a project that is developing future evolution strategies and design options for access networks, particularly point-to-multi-point passive optical networks (PONs). The objective is to find ways to scale current PON technologies to increase capacity and (potentially) reach, whilst at the same time constraining power consumption and cost and increasing flexibility in order to enable the dynamic support of multiple traffic and service types (including the front- and back-haul of 5G wireless traffic). This will involve the adoption of transmission techniques that are currently confined to use in metro and long haul systems e.g. use of advanced modulation formats, coherent detection, digital signal processing and dense wavelength division multiplexing and switching. The challenge is to develop approaches that enable the potential benefits of these technologies to be exploited at dramatically lower cost and in the burst mode operating regime that is required for PONs. The Researcher will design and model new III-V semiconductor-based, low cost photonic device solutions (tunable lasers, high speed modulators etc.) that will be required to enable these next generation PONs. The Researcher will work in close collaboration with device development groups at Tyndall to ensure fabrication of the new components and will also be responsible for the evaluation and demonstration of the new technologies within advanced PON system testbeds.
Key Duties and Responsibilities
- Design and modelling of new PON transceiver solutions, including low cost externally-modulated tunable lasers and associated wavelength control schemes.
- Working closely with internal and external partners to enable device fabrication and prototype transceiver test board sub-assembly.
- Experimental proof of concept and system test.
- A PhD in the area of electronic engineering, physics or equivalent
- A deep knowledge of III-V semiconductor technology in general and tunable laser and high speed modulator design and fabrication specifically.
- Direct experience of taking III-V optoelectronic devices from the design phase, through fabrication to test and characterisation.
- Knowledge of future PON systems and their photonic device requirements would be considered a plus.
Informal enquiries can be made in confidence to Prof. Paul Townsend, email, email@example.com.
