Photonic Devices Technologies for Advanced Optical Transceivers at 100Gbps and beyond

Abstract

In the last few years, the growth of large bandwidth services has increased exponentially the IP traffic demand in telecommunications networks. In this way, the development of innovative technologies that allow the optical systems evolution to higher data-rates and lower power consumption has become critical to meet the bandwidth demand for the next years. The current optical device technologies are made of a discrete component assemble and therefore increasing both density and power consumption. For these reasons, the integrated photonic technologies is attracting a lot of interest in the industry community for next generations of optical devices. In this context, this project proposal aims new integrated photonic device conception in order to provide solutions to improve the device performance without compromising its cost. The target applications are long-haul and metropolitan networks using coherent technology, acting in basic building blocks such as laser, transmitter and optical amplifiers. The main project challenge is to provide compact solutions, with efficient power consumption and present a competitive performance with the market demand. To achieve these goals, the main research lines are: product spectification definition for 100Gbps and 400Gbps technologies for target applications; study of new fabrication platforms as well as innovative photonic device architectures for next optical device generation; advanced photonic integrated circuit design; study and analysis of high-performance packging techniques; system validation of device prototypes.
