Optical Module Integration Engineering Intern (Summer 2026)

Overview

Join the Optical Module Engineering team at Lumentum, where you will help optimize and tune next-generation DataCom optical modules for maximum performance and reliability.

This internship focuses on system-level performance optimization, including improving key optical and electrical metrics such as TDECQ, BER, OMA, and signal integrity. You will work with cross-functional teams across optics, DSP, hardware, and test engineering to analyze multi-parameter datasets and identify the right tuning direction to enhance overall module performance.

You will gain hands-on experience with high-speed optical systems, automated test environments, and performance-driven engineering methodologies.

Responsibilities

As an Optical Module Integration Engineering Intern, you will:

• Assist in tuning and optimizing DataCom optical modules to improve TDECQ, BER, OMA, and related performance metrics.
• Analyze multi-dimensional datasets to understand performance trade-offs across optical, electrical, and DSP parameters.
• Develop Python automation scripts to control test equipment, collect measurement data, and streamline performance characterization.
• Process and visualize large datasets to identify key drivers limiting module performance.
• Correlate device-level parameters (e.g., laser bias, driver settings, equalization parameters) with system-level test outcomes.
• Propose data-driven optimization directions and validate improvements through controlled experiments.
• Support debug efforts for performance degradation or margin issues.
• Document findings and present technical results to engineering teams.

Location

This internship will be on-site in San Jose, California.

Minimum Qualifications

• Currently enrolled in a Bachelor’s or Master’s degree program in Electrical Engineering, Optical Engineering, Physics, or a related field.

Desired Qualifications

• Understanding of high-speed optical communication fundamentals (PAM4 signaling, eye diagrams, BER, TDECQ, OMA).
• Experience writing automation scripts in Python for data collection and analysis.
• Familiarity with laboratory test equipment such as oscilloscopes, BERTs, optical power meters, or spectrum analyzers.
• Ability to process multi-parameter datasets and identify performance optimization trends.
• Basic knowledge of signal integrity and DSP concepts is a plus.
• Strong analytical and problem-solving skills.
• Excellent communication skills and ability to work in a cross-functional engineering environment.
• Hands-on, detail-oriented mindset with interest in system-level optimization.

Pay Range: $23.75 - 54.30/hour USD
