Your Team Your Impact
Marvells 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 HighSpeed Optical Modeling Architect will be responsible for designing simulating and analyzing highspeed electrical & optical systems and components. This includes the development of optical models the integration of photonic devices with electronic systems and optimizing performance for highbandwidth and lowlatency applications. You will play a key role in advancing optical communication technologies helping drive the next generation of optical interconnects copackaged optics and highperformance networks.
Modeling and Simulation of Optics Drivers:
Develop models for highspeed optical drivers used to drive Silicon Photonic (SiPho) modulators (e.g. MachZehnder modulators (MZM) VCSELs.
Model the electrical characteristics of optical drivers to ensure the proper transmission of highspeed 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 highspeed applications.
SerDes I/O System Modeling:
Develop accurate and efficient models for highspeed SerDes interfaces focusing on both the transmitter and receiver.
Model the electrical behavior of highspeed 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 nonideal 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 highspeed links.
Implement and simulate techniques like channel equalization preemphasis and deemphasis to mitigate signal degradation.
What Were Looking For
Educational Background:
- A PhD or Masters degree in Optical Engineering Electrical Engineering or a related field with significant experience in optical communications and highspeed systems.
Experience:
- Proven experience (typically 10 years) in highspeed SerDes modeling Optucal modelling signal integrity analysis and I/O system design.
- Experience working with highspeed 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 systemlevel modeling of highspeed I/O systems.
