Objective
The objective of the project is to develop low-cost, 1.3um dilute nitride laser sources for use as directly-modulated transmitters in access applications. These applications require stable and reliable sources, which can be produced at very low cost and operated in an uncooled environment.
Dilute nitride lasers are expected to have significant advantages over InP-based devices in terms of both cost and temperature performance. Both edge-emitting lasers (EELs) and vertical cavity surface-emitting lasers (VCSELs) will be investigated for 2.5Gb/s and 10Gb/s applications. The materials development will focus on improving the optical efficiency and stability of the novel dilute nitride materials, exploring the use of growth chemistry and advanced composition-, bandgap- and strain-engineered active regions.
The epitaxial growth activities will exploit highly developed growth techniques and sophisticated epi-layer structures to enhance device performances while limiting the cost. The device processing activities will investigate advanced surface microstructures to boost the device performances, reduce the number of optical components and lower the packaging complexity. All device development activities will be supported by device modelling activities. The design activity will aim for suitable thermal, dynamic and modal performances and will examine large-signal modulation effects. Optimised VCSELs and EELs will be packaged and characterised.
The cost, performance and reliability of these devices will be compared with that of state-of-the art 1.3um InP-based EELs (optimised for access applications), both for current 1.0-2.5Gb/s applications and for emerging 10Gb/s applications. The direct digital modulation performance of these devices will be evaluated and standard network modelling tools and techniques will be used to assess their transmission performance.
