The project will develop, model and analyse a range of miniaturised light-processing devices for optical communications applications that rely soley on their geometrical design for their optical functionality. Such devices are less complex than devices that rely on other physical phenomena for their operation, such as interference, resonance or grating phenomena. They have potential application to a wide range of applications including optical telecommunications, optical sensing and biophotonics. The major outcome will be a range of novel devices that are very compact, have very low optical power loss and process light signals in ways that either cannot be readily achieved by other approaches or are simpler than other approaches.Read moreRead less
Asymmetric InP-based structures for high power laser diodes at 1400-1500 nm for pumping optical amplifiers used in communication systems. This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks. The low modal gain (confinement f ....Asymmetric InP-based structures for high power laser diodes at 1400-1500 nm for pumping optical amplifiers used in communication systems. This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks. The low modal gain (confinement factor) of this asymmetric structure is expected to reduce internal losses and hence increase the output power with better thermal dissipation. Single mode could be obtained by careful design in the trade-off between filamentation and threshold current. Ion implantation is also proposed to suppress higher order modes.Read moreRead less
Multi-Soliton Complexes. This project aims to investigate phenomena related to multi-soliton complexes in optics. Solitons have the potential of high speed data transmission across the world. Their use in telecommunications requires various component and extensive knowledge of their properties. Multisoliton complexes are essential in future devices for high speed information processing and transmission.
