Responsibilities
- Lead high-speed silicon photonics development, focusing on high-speed modulators (e.g., carrier-depletion Mach-Zehnder, micro-ring/micro-disk, and traveling-wave designs).
- Design and optimize modulators for EO bandwidth, VπL, insertion loss, extinction ratio, and energy per bit, using optical, electrical, and RF co-simulation.
- Lead layout and tapeout of photonic test vehicles and product blocks in foundry PDKs, including DRC/LVS sign-off and design-for-test structures.
- Define RF electrode, termination, and driver-interface requirements together with the electronic IC and packaging teams.
- Support wafer- and die-level testing (small-signal EO S-parameters, eye diagrams, BER, DC/thermal tuning), and correlate measured results with models to improve the next design.
