Your Team, Your Impact
Marvell's Platform Business Unit is seeking a dynamic Senior principal Optical modelling Architect to build the next generation of Optical Connectivity architectures for Accelerated infrastructure.What You Can Expect
The High-Speed Optical Modeling Architect will be responsible for designing, simulating, and analyzing high-speed electrical & optical systems and components. This includes the development of optical models, the integration of photonic devices with electronic systems, and optimizing performance for high-bandwidth and low-latency applications. You will play a key role in advancing optical communication technologies, helping drive the next generation of optical interconnects, co-packaged optics, and high-performance networks.
Modeling and Simulation of Optics Drivers:
Develop models for high-speed optical drivers used to drive Silicon Photonic (SiPho) modulators (e.g., Mach-Zehnder modulators (MZM), VCSELs).
Model the electrical characteristics of optical drivers to ensure the proper transmission of high-speed signals to optical modulators.
Focus on key parameters like pulse shaping, voltage swing, and rise/fall time to achieve the required data rates (e.g., 100 Gbps or higher).
Simulate the performance of the optical driver under various operating conditions, including temperature variations and voltage fluctuations.
Transimpedance Amplifier (TIA) Modeling:
Develop models for TIA circuits, which convert the photocurrent generated by photodetectors (e.g., PIN diodes, avalanche photodiodes (APDs)) into a voltage signal.
Model key aspects of TIAs, including feedback resistors, bandwidth, noise characteristics, and linearity to ensure high sensitivity and low distortion.
Analyze the impact of thermal noise, shot noise, and jitter on TIA performance in high-speed applications.
SerDes I/O System Modeling:
Develop accurate and efficient models for high-speed SerDes interfaces, focusing on both the transmitter and receiver.
Model the electrical behavior of high-speed I/O circuits, considering factors like clock data recovery (CDR), equalization, and voltage swing.
Use simulation tools (e.g., Cadence, Keysight ADS, Synopsys HSPICE) to simulate the performance of SerDes systems in both ideal and non-ideal conditions.
Signal Integrity Analysis:
Perform signal integrity simulations, including eye diagram analysis, bit error rate (BER) analysis, and jitter analysis for SerDes I/O interfaces.
Model and analyze the impact of noise, crosstalk, skew, and reflections on the signal quality and timing in high-speed links.
Implement and simulate techniques like channel equalization, pre-emphasis, and de-emphasis to mitigate signal degradation.
What We're Looking For
Educational Background:
- A PhD or Master's degree in Optical Engineering, Electrical Engineering, or a related field with significant experience in optical communications and high-speed systems.
Experience:
- Proven experience (typically 10 years) in high-speed SerDes modeling, Optucal modelling, signal integrity analysis, and I/O system design.
- Experience working with high-speed communication protocols such as PCIe, Ethernet is a MUST.
- Experience with SerDes I/O performance at speeds of100 Gbps, 200Gbps and beyond is highly preferred.
- Experinece with modelling of Opto electronic components such as Silicon Photonics Driver, TIA is highly preferred
Programming and Tools:
- Proficiency in programming languages such as Python, C , or Matlab for automation, data analysis, and creating custom simulations.
- Experience with simulation tools (e.g., Cadence, Keysight ADS, Synopsys HSPICE) for circuit and system-level modeling of high-speed I/O systems.
