Job summary

Lumentum is seeking a PhD-level optoelectronics expert to design GaAs-based VCSEL devices and technology platforms in a collaborative environment in California. The role involves epitaxial growth, wafer fabrication, device characterization, and data-driven optimization to push performance and manufacturability.

You will coordinate with internal teams and contract manufacturers, contribute IP, and leverage software tools like Python and Matlab for data analysis and modeling, while communicating

Qualifications

• PhD in optoelectronics or Master with 3+ years experience is the minimum requirement; PhD with industry experience is preferred.
• Experience with VCSEL design and wafer fabrication.
• Knowledge of semiconductor device physics, process technology and equipment.
• Experience with software data analysis tools (Excel, JMP, Minitab), photomask layout, and data processing (Python, Matlab).
• Excellent ability to work in cross-functional teams as both a team leader and a contributor.
• Strong verbal and written communication skills.

Responsibilities

• Design GaAs-based VCSEL devices and VCSEL technology platforms.
• Develop design and fabrication flows (mask layout, EPI structure, etching, metallization, passivation, implantation, oxidation, wafer fusion).
• Characterize devices with LIV, spectra, polarization stability, and beam parameters under CW and pulsed operation.
• Analyze data to link device characterization to design inputs and improve performance.
• Coordinate with internal groups and contract manufacturers to transfer designs to manufacturing and release.
• Generate key IP from new design and manufacturing ideas.

Job description

It's fun to work in a company where people truly BELIEVE in what they're doing! We're committed to bringing passion and customer focus to the business.

If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!

About Lumentum

At Lumentum, we're building the tech behind the world's fastest networks and most advanced systems. Our optical and photonic solutions power everything from AI and cloud computing to data centers, telecom, and advanced manufacturing.

We're a global team of innovators working where light meets technology, solving big challenges that keep the world connected and moving forward. If shaping the future of connectivity excites you, you'll fit right in.

What You'll Be Doing

• Design of new GaAs-based VCSEL devices and VCSEL technology platforms
• Apply knowledge and experience with epitaxial growth and wafer fabrication techniques develop the design (mask layout, EPI structure) and fabrication flow (etching, metallization, dielectric passivation, implantation, oxidation, wafer fusion, etc.)
• Device characterization including laser diode testing at wafer probe and chip-on-carrier for light-voltage-current (LIV), spectra, polarization stability, near-field and far-field beam parameters under CW, ms pulsed and ns pulsed operation.
• Data analysis and understanding of device physics to correlate the device characterization to design inputs (epi, fab, emitter design and die layout) and use this information along with modeling tools to improve device performance
• Coordinate with groups within Lumentum and at contract manufacturers to bring the new designs, wafer fabrication flows and device characterization methods into manufacturing and product release
• Generating key intellectual property (IP) from new ideas in design and manufacturing

What We're Looking For

Education:

PhD degree in optoelectronics or other relevant major or Master's degree with 3 years of experience is minimum requirement. PhD with industry experience is preferred..
