Infinera 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 next-generation 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 high-speed 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, high-speed 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

Infinera’s next generation communications platform will be defined, developed, characterized, and optimized on your optical testbed. Your experimental data will fuel our design, starting with off-the-shelf 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 high-speed oscilloscope and performing coherent signal processing on waveforms, and measuring bit-error 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 performance-critical aspects such as powerup self-calibration, receive acquisition, real-time performance monitoring, and in-service 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
