Adaptive Software Defined Terabit Transceiver \nfor Flexible Optical Networks

Project description


Core and disruptive photonic technologies
ASTRON has set specific objectives that focus on the design and development of all the necessary optical and electronic components as well state of the art algorithms to implement the software defined

ASTRON aims at the development of high-capacity, energy-efficient and bit-rate flexible optical transceivers capable of supporting rates from 10Gb/s to beyond 1Tb/s. The ASTRON concept is based on developing multi-functional and agile devices so as to achieve Terabit capacities on a single photonic integrated chip. ASTRON's transceiver can realize different techniques of flexible super-channel generation (OFDM/Nyquist WDM) and does so without requiring any IDFT/DFT processing in the electronic domain, thus achieving ultra-high capacity with significant improvements on the energy efficiency per transmitted bit. To implement optically the IDFT/DFT functions, a special design arrayed waveguide grating (AWG) based planar lightwave device will be developed.ASTRON relies on the combination of InP monolithic elements and Silica planar lightwave circuits for achieving cost-effectiveness, high yield, low power consumption and device scaling far in advance of the level commercially available today. The transmitter module that implements the optical super-channels employs a planar optical multi-channel Silica motherboard carrying four hybridly integrated InP-based twin-IQ Mach-Zehnder Modulators in combination with a novel 8x8 AWG-based waveguide structures on board. The receiver is a fully integrated, multi-channel optical coherent receiver module consisting of a similar 8x8 AWG-based waveguide structure with DFT functionality, eight 90° hybrids and high speed balanced photo-detector arrays of 32 active elements per polarisation, hybridly integrated onto a Silica motherboard. Additionally, ASTRON will develop advanced digital signal processing algorithms for impairment mitigation and a novel software-defined signal processing module that renders the transceiver flexible in terms of format, bit rate and spectrum utilization. Each component within this project is not just aimed for a one time demonstration but is fabricated keeping one eye on commercialisation.
