Participation in projects:
Industry Driven Elastic and Adaptive Lambda Infrastructure for Service and Transport
- Networks – EU FP7 IDEALIST (2012–2015). The project aims at designing and developing innovative transport solutions, compatible with new bandwidth consuming applications (e.g. 3D video, cloud, etc.) based on Elastic Optical Networks equipped with a multidomain and multi-technology control plane enabling adaptive network and service interworking. Conducted by an international consortium.
- Modelling and optimization of elastic optical networks for 100+ Gbit/s – ESO (2011–2014), granted by the National Science Centre (NCN) within the SONATA program, concerns the design of elastic optical (fibre) communication networks being a successor of the current DWDM networks and able to support efficiently the multi-rate and huge-bandwidth (100+ Gb/s) connections provisioning for the current and next generation Internet networks.
- In 2013, various aspects of elastic optical networks (EON) were addressed, especially: data center location, provisioning of cloud computing traffic, elastic spectrum allocation for time-varying traffic, and dedicated path protection. The project achievements were presented in several publications listed in Journal Citation Report and at leading international conferences in optical networking field.
- Monitoring System for Telecom Infrastructure – SMIT (2012–2014), executed with Asseco Poland PLC. This project is aimed at the development of versatile, centralized monitoring system for telecom plant (cable lines, manholes, street cabinets, base stations of mobile networks, etc.), capable of automatic detection of cable cuts, facility break-ins and slowly-developing failures by means of advanced data analysis software. SMIT system is communicating with Supervision Center over IP data network. The system also includes electronic sensors deployed in unmanned facilities, used for detection of break-ins, attempts of cable theft, flooding, extreme temperature, explosive gas, etc. Events recorded by the system are displayed on maps and memorized in database. The system is being tested by Orange Polska and can be adopted to monitor other kinds of facilities as well. The project was run jointly by Z2 and Z14 Departments
- COST Action TD1001 Novel and Reliable Optical Fibre Sensor Systems for Future Security and Safety Application OFSeSa (2010–2014).
- COST Action IC 0804 Energy Efficiency in Large Scale Distributed Systems (2009–2013).
Achievements in 2013:
- Models and algorithms were developed for optimization of various network scenarios. In particular: an advanced optimization algorithm for solving design problems including routing and spectrum allocation in EONs, based on column generation technique; optimization algorithms for semi-transparent OBS networks.
- Several models of signal propagation and estimation of NLI power increase in single-mode optical fibre were developed, including guidance of orthogonal polarization modes and Raman amplification. The Gaussian Noise (GN) theoretical model was adopted to calculate transmission reach in EON networks, useful for network optimization.
- Advanced research in the field of developing theoretical/numerical methods for investigation of plasmonic photonic structures was done, with a significant progress in understanding and applications of micro- and nanoscale optical phenomena. This research included in particular: lattices of Ag nanowires, double-periodic gyrotropic layers,optical fiber vector sensor for bending and strain, temperature sensors based on ring waveguides filled with liquid crystals, microwave electro-optic modulators based on FP micro-resonators
