Photonics characterization meets silicon photonics testing at Lightmatter for Winter 2026. Develop Python automation while analyzing electro-optic components in laboratory settings.

This internship suits a PhD candidate or recent PhD graduate in Photonics, Electrical Engineering, Physics, or a related field. You will characterize photonics chips and devices, test micro-rings and Mach-Zehnder interferometers, and operate optical and semiconductor equipment. The team develops photonic processors and interconnects for AI and high-performance computing infrastructure.

Key Responsibilities:
Conduct electro-optic testing of photonics chips and devices
Characterize micro-rings, phase shifters, and interferometers
Operate lasers, modulators, receivers, and spectrum analyzers




Design testing protocols for chips and subsystems
Automate testing and system interfacing using Python

Requirements:
PhD candidate or recent PhD graduate in Photonics
Solid understanding of silicon photonics
Demonstrated electro-optic component testing experience
Python automated testing development experience
Analytical, independent, and process-oriented laboratory approach

Apply photonics characterization, electro-optic testing, and Python automation skills to Lightmatter’s advanced silicon photonics development.
