Research Fellow (LITHIUM NIOBATE ENGINEER)

Job Description

We are seeking a highly motivated Lithium Niobate Engineer (PhD required) to lead the design, fabrication, and integration of cutting-edge photonic devices for hybrid photonic neural networks.

The role focuses on developing nonlinear optical activation functions using ring resonators in periodically poled lithium niobate (PPLN), optimizing their performance through simulations and innovative poling techniques, and integrating them with Mach-Zehnder interferometer (MZI) meshes for linear photonic operations.

The successful candidate will advance the fabrication of low-loss PPLN devices, implement thermal and electro-optic tuning mechanisms, and contribute to system-level integration and validation on AI benchmark tasks, driving innovation in energy-efficient, scalable optical computing.

Qualifications

• PhD in Physics, Electrical Engineering, Materials Science, or a closely related field, with strong expertise in nonlinear optics and lithium niobate photonics.
• Hands-on experience in photonic device design, including ring resonators, waveguides, and MZI meshes, supported by modeling and simulation tools (e.g., COMSOL, Lumerical).
• Proven track record in nanofabrication techniques, including ICP-RIE etching, periodic poling, and fabrication of curved waveguide structures.
• Familiarity with electro-optic and thermal tuning methods for photonic devices, and experience in system-level optical integration.
• Strong analytical and experimental skills, with experience in validating photonic devices on benchmark tasks such as classification and regression.
• Ability to work independently and collaboratively in a multidisciplinary team, translating advanced research concepts into functional photonic systems.
• Open to Fixed Term Contract.
