Active modulation of light with large optical bandwidths (∼100 nm [1]) is required in photonic devices, such as modulators for fiber communications [1] and saturable absorbers for ultrafast pulse generation [2,3]. Present modulators use expensive materials, (e.g. LiNbO3 [4], III-V semiconductors [5], and Ge on silicon-on-insulator (SOI) [6]), and are limited by narrowband operation (∼20 nm for quantum-confined...
A 1 Gbps 105.4 GHz wireless link is demonstrated by directly modulating a photonic integrated dual-laser source. A 50 m link is predicted to be able to achieve error free operation using FEC following optimisation.
In this paper, we investigate the deployment and capacity of delivering mobile WiMAX based on IEEE 802.16e-2005 from aerial platform such as High Altitude Platforms (HAPs). A urban scenario and an suburban scenario with mobile broadband usages as complement or substitute to the fixed Internet connection are developed to compare the delivery of broadband services from terrestrial and aerial platforms...
