R&D VCSEL Designer

Lumentum • San Jose, CA

11d • $112,050 - $192,500

About The Position

The R&D VCSEL Designer designs new GaAs-based VCSEL devices and technology platforms, applying knowledge of epitaxial growth and wafer fabrication to develop device designs and fabrication processes. The role characterizes devices, analyzes performance in relation to design inputs, and uses modeling tools to improve device performance. It also coordinates with internal Lumentum teams and contract manufacturers to bring designs, fabrication flows, and characterization methods into manufacturing and product release, while generating intellectual property from design and manufacturing ideas.

Requirements

• PhD in optoelectronics or another relevant major, or a Master's degree with at least 3 years of experience.
• Experience with VCSEL design and wafer fabrication.
• Knowledge of semiconductor device physics, process technology, and equipment.
• Experience with software data-analysis tools such as Excel, JMP, or Minitab.
• Experience with photomask layout and data processing using Python or Matlab.
• Ability to work effectively in cross-functional teams as both a team leader and contributor.
• Strong verbal and written communication skills.

Nice To Haves

• PhD with industry experience.
• Optoelectronic device modeling, including electrical, optical, and thermal modeling.

Responsibilities

• Design new GaAs-based VCSEL devices and VCSEL technology platforms.
• Develop device designs, including mask layouts and epitaxial structures, and fabrication flows using techniques such as etching, metallization, dielectric passivation, implantation, oxidation, and wafer fusion.
• Characterize devices through laser diode testing at wafer probe and chip-on-carrier for light-voltage-current (LIV), spectra, polarization stability, and near-field and far-field beam parameters under CW, millisecond-pulsed, and nanosecond-pulsed operation.
• Analyze data and apply device-physics understanding to correlate characterization results with epitaxy, fabrication, emitter design, and die-layout inputs.
• Use analysis and modeling tools to improve device performance.
• Coordinate with Lumentum groups and contract manufacturers to transition designs, wafer fabrication flows, and characterization methods into manufacturing and product release.
• Generate intellectual property from new design and manufacturing ideas.

Benefits

• Flexible time off.
• Health and wellness benefits, including physical and mental wellness.
• Tuition reimbursement and career growth support.
• Free gym, games room, and prayer room.
• Subsidized meals and free coffee and tea.
• Employee stock options and incentive plans.
• Competitive total compensation packages, which may include annual bonus, commission for certain sales roles, equity, and health and welfare benefits.
