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.
