Job Description

Qualifications

  • PhD. in Electrical Engineering or Applied Physics with minimum of 3 years of industrial 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.
  • Handson experience working with systemlevel optical communication hardware 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 highspeed RF and mmwave interconnects, amplifiers, and components.
  • Characterization of RF/mmwave systems, such as S parameter measurements, jitter measurements, and ADC/DAC performance and ENOB
  • Handson experience with highspeed optical and electrical test, and measurement equipment control and data acquisition.
  • Programming experience in Matlab, Python, VB.net, or C desired.

Nokia is seeking a Coherent Optical System Architect to join our Optical Systems Group (OSG). The engineer will be responsible for contributing to the development of leading coherent MODEMs based on Infinera's nextgeneration coherent photonic integrated circuits (PICs). The ideal candidate will be prepared to work with early prototype hardware to get an initial look at product performance and provide rapid feedback to the PIC and highspeed analog ASIC teams. Performance characterization will include MODEM SNR, OSNR tolerance, systematic breakdown of the MODEM impairment penalties, sensitivity studies and model alignment. OSG works closely with many parts of the company and the candidate should anticipate frequent interactions with the coherent ASIC team on coherent signal processing issues and ADC/DAC ENOB, with optical, highspeed analog ASIC, and systems engineering teams. A key component of this role is the ability to understand and make tradeoffs between optical, electrical, and digital capabilities in order to optimize the overall system performance.

Responsibilities

Nokias next generation communications platform will be defined, developed, characterized, and optimized on your optical testbed. Your experimental data will fuel our design, starting with offtheshelf components, evolving to prototype PICs, and eventually taking the form of the final integrated embedded systems or coherent pluggable modules. This requires ownership of the optical design, optimization methods, and stabilization techniques. One particular component of your research will be pushing our optical systems to higher baud rates.

Frequently used diagnosis capturing coherent waveforms on a highspeed oscilloscope and performing coherent signal processing on waveforms, and measuring biterror rate performance in the presence of optical noise and other impairments. Of particular interest will be pushing to faster baud rates.

Through frequent interaction with the control & firmware teams, you will assist in optimizing performancecritical aspects such as powerup selfcalibration, receive acquisition, realtime performance monitoring, and inservice performance optimization. These algorithms will be tested during the implementation stage to ensure they operate properly.

Results will be presented internally and documented as electrical and optical performance specifications for nextgeneration platforms.

Some customerfacing interactions may be required, such as field trials using prototype equipment, or debugging unusual field failures that cannot be resolved through the normal customer service process.
