Senior Silicon Photonics PIC Architect

Coherent Corp.; Fremont (CA); Hybrid; USD 140,000 - 210,000; Full time

Job summary

Coherent Corp. in Fremont, CA is seeking a highly skilled photonics engineer to design and optimize high-speed photonic devices andPICs for next-generation optical interconnects and co-packaged optics.

You will collaborate with foundry teams, simulate RF and EM effects, and translate system requirements into robust device specifications. This role demands a PhD or Master’s in a related field and hands-on PIC tapeout experience.

Qualifications

• PhD or Master’s in Electrical Engineering, Photonics, Applied Physics, Optics or related field.
• Significant experience in integrated photonics or silicon photonics design and development.
• Experience designing high-speed electro-optic devices and their RF structures.
• Experience with electromagnetic and RF simulation tools such as HFSS, CST, ADS, or similar.
• Experience with photonic simulation and design tools such as Lumerical, Tidy3D, RSoft, or equivalent.
• Experience designing WDM components or wavelength-selective photonic circuits.
• Experience taking PIC designs through layout and tapeout using foundry PDKs.

Responsibilities

• Develop new photonic device and PIC concepts for next-generation optical interconnects and high-speed communication systems.
• Design and optimize high-speed photonic components and subsystems for 400G-per-lane links and co-packaged optics.
• Work on interaction between photonic devices and electrical/RF interfaces including modulators, photodetectors, transmission lines, and interconnects.
• Develop WDM building blocks and architectures such as wavelength filters and wavelength-selective devices.
• Translate system-level requirements into practical photonic device and circuit specifications.
• Evaluate tradeoffs in bandwidth, optical loss, power, footprint, manufacturability, and scalability.
• Model device performance using optical, EM, and RF simulation tools.
