Job Description

Company Overview

OpenLight Photonics is an innovative start-up at the forefront of photonic integration, commercializing our cutting-edge heterogeneously integrated photonic platform. Join us in an exciting start-up environment with ample opportunities for growth and professional development.

Position Summary:

As a member of OpenLight’s Silicon Photonics (SiPh) team, the candidate will be responsible for the development, design, and integration of high-speed opto-electronic devices in OpenLight’s proprietary heterogenous silicon-IIIV photonic platform. The candidate will lead the design of high-speed components (200 Gbit/s and beyond) including IIIV modulators and detectors. The candidate will also support characterization and validation of the fabricated device performance and build compact models for OpenLight’s open market PDK.

The successful candidate requires a deep knowledge of III-V opto-electronic high-speed device theory and a proven track-record in bringing photonic integrated circuit (PIC) based products to market. The candidate will work cross-functionally with PIC architects, high-speed systems, reliability, fabrication and packaging engineers in order to define, design and validate high-speed optoelectronic devices using OpenLight’s SiPh technology.

Key Responsibilities

• Design and optimize high-speed III-V-based optical modulators and detectors, including EAM and Mach-Zehnder Interferometers (MZIs), IIIV pin and UTC detectors, using industry-standard photonics design tools.
• Analyze experimental results, compare them with simulations, and refine device designs and generate compact models for OpenLight PDK.
• Publish and maintain equivalent circuit models and generate design documentation for high-speed photonic devices for OpenLight PDK documents and models.
• Collaborate with layout and fabrication teams to define mask-layouts and process flows to fabricate photonic devices.
• Work closely with system engineers to integrate modulators into high-speed system validation hardware.
• Support test engineers with high speed device test development and characterization.
• Stay up-to-date with advancements and industry trends in Silicon photonics and III-V high-speed modulators, detectors and optical interconnect hardware.
• Publish in technical journals, conferences, and submit novel ideas for patent generation to contribute to the company’s innovation portfolio.

Qualifications

• PhD in Electrical Engineering, Materials, Physics, or a related field.
• Minimum 10+ years of industry experience designing Si-Ge and/or IIIV high-speed modulators and detectors for transceiver products.
• Strong background in semiconductor high-speed device physics in Si-Ge and/or III-V material.
• Hands-on experience with high-speed device simulations and circuit design tools (e.g Ansys HFSS, CST, ADS, Sentaurus TCAD, Crosslight).
• Experience with RF characterization of photonic devices (transceiver modules is a plus)
• Knowledge of relevant semiconductor fabrication processes.
• Strong analytical and problem-solving skills with the ability to work in a fast-paced, collaborative environment.
• Excellent written and verbal communication skills for technical documentation and reporting.
