Engineer - Optical Systems

Huawei Technologies Canada Co., Ltd.•Ottawa, ON

3d•CA$106,000 - CA$156,000•Onsite

About The Position

Huawei Canada's Advanced Optical Technology Lab focuses on advanced R&D in high-performance optical communications and networking. Our expert team specializes in transmission algorithms, systems, physics, and optical network management. The lab engages in projects ranging from deep research to developing key product features, actively participating in standards organizations and collaborative research with partners. Our multicultural environment fosters innovation, mentorship, and a passion for learning. If you thrive on solving complex technical challenges, this lab is your ideal place. Develop models for high-speed optoelectronic components for optical communication transmission systems including optical modulator, laser source, optical drivers, TIA circuits, photodetectors (e.g., PIN diodes, avalanche photodiodes (APDs)), etc. Develop fiber channel models including single, multi-mode, and hollow-core fibers for optical communication transmission systems (e.g. polarization mode dispersion, multi-mode dispersion and multi-path interference). Based on theoretical modelling, simulation and experimental characterization, investigate the impact of device impairments in high-speed applications such as driver nonlinearity, laser intensity and phase noise, clock jitter and TIA thermal noise, etc. Set up offline/on-line test bed to investigate pre- and post- forward error correction (FEC) transmission performance for high-speed direct- and coherent-detection optical communication systems. Closely work with DSP, ASIC design and modem control teams to identify system impairments sources and provide solutions to improve performance of direct and coherent-detection transceivers.
