MIT Lincoln Laboratory Compound Semiconductor Process Engineer in Lexington, Massachusetts

When NASA made history in 2013 with the longest laser communication link ever demonstrated (from a Moon-orbiting satellite to Earth), our group was behind the satellite's laser transmitter and the ground terminals' highly sensitive photon detectors that enabled the link. We have a long history of developing advanced solid-state, fiber, and diode laser technologies for the scientific and defense communities. Recently, our lasers have been key to enabling cutting-edge ladar systems that can map terrain with greater accuracy and area coverage rates, providing much needed capabilities in disaster relief efforts, such as the disaster mapping of Hurricanes Harvey and Irma in 2017. We are also creating cryogenic-laser-based illuminators for airborne sensors that can detect and track fast-moving objects with highly dynamic platform motion. Finally, we've led the laser community in developing beam-combining techniques for high-energy laser systems. Using these techniques, our fiber laser system have demonstrated record-breaking levels of beam brightness and near-ideal beam quality. In 2022 and beyond, we continue to push the envelope of laser technology across a very broad range of wavelengths.

Position Description

The Laser Technology and Applications Group seeks an individual to support the development and fabrication of compound semiconductor optoelectronic devices. These devices find applications in a wide range of systems including directed energy, lidar, sensing, and communications. Example devices include high-power diode and quantum cascade lasers, optical amplifiers, high-current waveguide photodiodes, wideband optical modulators, and photonic integrated circuits. Fabrication of these devices involves leveraging InP, GaAs, and GaN material systems and their associated compositions. The successful candidate will be a member of a multi-disciplinary team whose mission is to develop packaged prototypes of advanced devices and integrated subsystems.

Required Qualifications

  • Bachelor’s degree in Electrical Engineering, Chemical Engineering, Materials Science, Physics, Chemistry or related field

  • 5 or more years of experience in the fabrication of compound-semiconductor (III-V) devices

  • Direct experience with compound semiconductor fabrication equipment and processes for device production, e.g., lithography, wet etching and component preparation, reactive-ion etching, sputtering and e-beam deposition of metal and dielectric materials, wafer and device cleaving

  • Experience working in a clean room laboratory, either in educational or professional settings

  • Excellent documentation and communication skills

Preferred Qualifications

  • 10 or more years of experience in the fabrication of compound-semiconductor (III-V) devices

  • Experience with device design and layout software, such as L-Edit or KLayout

  • Experience with fabrication planning and team management

  • Experience in both research laboratory and industrial production environments

  • Familiarity with the interplay between III-V device fabrication, packaging and performance

  • Familiarity with chemistry, electrical and optical characterization techniques, packaging approaches, and epitaxial material growth is a plus
