Huawei Canada has an immediate permanent opening for a Senior Engineer.
About the Team:
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.
About the Job:
-
Develop models for high-speed optoelectronic components for short-reach
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- and multi-mode and hollow-core
fibers for short-reach 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.
-
Develop accurate and efficient models for high-speed analog/digital devices
including SerDes, analog-to-digital convertor (ADC) and digital-to-analog
convertor (DAC). Investigate and characterize the impairment caused by
mismatch of time-interleaving ADC and DAC.
-
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 short-reach 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.
About the ideal candidate:
-
PhD/Master's Degree in Electrical Engineering, Optical Engineering, Physics.
-
Simulation and modeling experience in optoelectronic components and optical
fiber communications.
-
Strong proficiency in Python, C/C++, Julia.
-
Hands-on experimental experience in optical system testing, real-time and
offline performance characterization for transceivers.
-
Knowledge of digital signal processing (DSP) and information theory.
-
Industrial experience in short-reach optical communication systems is an
asset.
-
Knowledge of Machine Learning is an asset.
