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
