Responsibilities
Nokia’s next generation communications platforms are defined, developed, and optimized based on sophisticated, end-to-end simulation platforms that are continuously fed with measurements of early prototypes and mature hardware
As the design space of modern optical engines is infinitely vast compared to prototype development and timescales of semiconductor device fabrication, your simulation results will guide our design and lead key design decisions from initial product definition to early design phases of MODEM development to configuration optimization in the final stages of manufacturing and production
This requires a detailed and deep understanding of all MODEM impairments in the digital, analog and optical domain
You will be evaluating the effectiveness of state-of-the-art digital signal processing algorithms, estimating the impact of transistor-level design choices in analog circuits and predict the MODEM performance penalties of integrated optical components such as Mach-Zehnder modulators and semiconductor optical amplifiers
Furthermore, you will be projecting the reach of our optical engines based on various linear and nonlinear impairments of the optical fiber channel and deployed line-systems
Through frequent interaction with the relevant design teams, you will assist in design, finding relationships between low level hardware specifications and its system level impact and optimizing performance-critical aspects to maximize overall modem performance
Results will be presented internally and documented as electrical and optical performance specifications for next-generation platforms
Some external and customer-facing interactions may be required, such as expected improvements of our next-generation engines on customer networks and contributing to forums discussing multi-source vendor agreements
Qualification
Required
PhD. in Electrical Engineering or Applied Physics with 0- 3 years of industrial or academic experience in optical communications, photonics, high speed electronics or systems
Fundamental understanding of optical communication systems, DWDM transmission systems, fiber transmission penalties, photonic integrated components, electronic (integrated) circuits, and signal analysis and processing
Experience and a strong mathematical understanding of the analytical and numerical modelling of system-level optical communication systems and components
Extensive understanding of coherent communications systems, including experience with QPSK, 16QAM, and 64QAM, as well as coding and forward error correction algorithms
Experience characterizing high-speed RF and mm-wave interconnects, amplifiers, and components such as S parameter, jitter, ENOB, nonlinear compression and their system implications
Experience in the characterization and modeling of various linear and nonlinear signal impairments, e.g., filtering, noise, nonlinear amplitude and phase distortions, dispersion etc
Programming experience in Matlab, Python, VB.net, or C desired
