A funded Ph.D. is available, focusing on the experimental analysis of the gain and loss mechanisms in telecoms optical devices based on dilute bismide and dilute nitride alloys.
Current telecomm components suffer severely from intrinsic losses with around 80% of electrical power wasted in a 1.55 micron laser chip as heat. Most systems then require thermo-electric coolers and an air-conditioned environment, further increasing the energy budget by over an order of magnitude. The losses are due to Auger recombination in semiconductor lasers and optical amplifiers (SOAs), and due to the temperature dependence of the energy gap in electro-absorption modulators (EAMs). As part of BIANCHO, an EU 7th Research Framework project, we propose a radical change, to manipulate the electronic band structure of novel dilute bismide and dilute nitride alloys of GaAs and InP to eliminate Auger recombination and dramatically reduce the temperature dependence of the energy gap.
Applications are invited from students who have, or expect to gain, a first or second class honours degree in physics or a similar discipline.
Informal enquiries concerning this studentship can be made to: Prof. Eoin O Reilly or Dr. Simon Osborne (tel. + 353 (0)21 490 4178; email: simon.osborne@tyndall.ie).
