Staff - Optical Integration Engineer - Product Development Infinera is searching for an Optical Engineer to join the Optical Module Group in Sunnyvale, CA for the development of new Photonic Integrated Circuit (PIC)-based, high speed, and advanced modulation digital coherent optical engines. The candidate should have a solid foundation spanning optoelectronic devices and their contributions in performance impairment of the coherent optical MODEM, fundamental blocks in the coherent digital signal processing chain, coherent optical test and measurement methods, and software automation. Experience with optical link design including power budgets, OSNR measurement and calculations, fiber penalties (CD, PMD, nonlinearities), and critical components specifications like laser FM-noise and ADC/DAC ENOB is essential. Job Summary - The broad job responsibilities include the hands-on testing and characterization of PIC-modules and digital coherent optics (DCO) subsystems.
- 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.
- Through frequent interaction with the firmware and controls teams, you will assist in optimizing performance-critical aspects such as powerup self-calibration, receive acquisition, acquisition robustness, performance tuning and tradeoffs between the DSP engine and the PIC-module, 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 performance specifications for next-generation platforms.
- The successful candidate will work closely with optical system group (OSG), DSP, Photonic Integrated Circuit (PIC), ASIC, module design, and product engineering teams to ensure quality release of new products starting from architecture and design phase all the way through to the manufacturing release.
