This is a hybrid position, the candidate must be able to work from the OpenLight Santa Clara or Goleta, CA office.

Responsibilities

As a member of OpenLight’s Silicon Photonics (SiPh) team, the candidate will be responsible for the development, design, and integration of opto-electronic devices in OpenLight’s heterogeneous silicon-IIIV photonic platform.

The candidate will lead the design and qualification of III-V epitaxial materials for electro-absorption modulators, in-plane single-frequency lasers and tunable lasers, amplifiers, and other optoelectronic components. The candidate will support DFB laser development programs. The candidate will work with the team on device design, characterization and validation of the fabricated epi and device performance, and building compact models for OpenLight’s PDK.

The successful candidate requires a deep knowledge of III-V opto-electronic 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, RF, process, layout, test and reliability engineers in order to define, design, integrate and validate high-power and high-speed optoelectronic devices using OpenLight’s SiPh technology.

• Lead design and simulation of III-V epitaxial materials for electro-absorption modulators, lasers, amplifiers, and detectors
• Work closely with external epi vendors to characterize and improve epi designs
• Define qualification plans for external epi vendors
• Design and simulate DFB lasers, and execute DFB laser development runs
• Define device CAD layouts in close collaboration with integration and layout engineers
• Develop compact models for III-V devices in OpenLight’s SiPh PDK
• Work with process engineers to define and optimize the device structures and processes
• Work closely with test engineering to define characterization strategy of IIIV devices on both wafer and die levels, as owner of data analysis and parameter extractions
• Work with reliability engineering to define qualification and reliability strategy, and perform device centric failure analysis in close collaboration with integration and process engineers
• Work closely with PIC and system architects to validate device performance versus specifications

Skills and Preferred Experience

• Ph.D. in Electrical Engineering, Applied Material Science, Applied Physics or related discipline
• 5+ years of relevant professional experience
• Strong hands-on knowledge of epitaxial layer design and simulation of IIIV photonic devices in particular lasers, amplifiers and modulators, with experience on commercial software like Harold, Crosslight, Silvaco or similar
• In-depth knowledge of device physics and design of optoelectronic III-V devices in particular lasers and amplifiers.
• Knowledge of laser cavity and grating design
• Knowledge of photonics simulation techniques (EME, FDTD) and hands-on experience with commercial design and modelling software (Lumerical, Rsoft, Photon Design or similar)
• Good understanding of integrated photonics and semiconductor Si and III-V processing
• Proficiency in programming with scripting languages, preferably Python
• Understanding of opto-electronic device requirements for datacom and LiDAR applications
• Hands-on experience with photonic device characterization. High-speed RF measurement is a plus, but not required
• Strong problem-solving, communication, organizational, interpersonal and presentation skills
