Physics | Optics internship: investigation of electro‑optic modulator leakage mechanisms

ASML focuses on developing innovative solutions to maximize the production of extreme ultraviolet (EUV) light by harnessing high-power source lasers. The primary goal of this internship is to investigate the leakage mechanism of an EOM (Electro-Optical Modulator). To achieve this, you will perform tests on different EOM parameters such as incident angle, input polarization, high-voltage setting, etc., and measure the resulting transmission and leakage through an EOM. The final objective is to establish a clear understanding of EOM performance. This project offers a valuable and hands-on learning experience for an intern.

Your Assignment

Your main tasks will include:

• Familiarize yourself with the work done on EOM leakage mechanism in ASML;
• Read up on literature on the EOM leakage mechanism;
• Help in building the set up and then perform EOM measurements;
• Analyze the effect of each parameters on the leakage and determine the relation between the parameters and the leakage behavior;
• Analyze the measurements and possibly propose a design or improvements;

Your Profile

To be a fit for this assignment, you:

• Are studying a master's in Physics, Optics or relevant;
• Are proactive and self-propelling;
• Possess data analysis and problem-solving skills;
• Have some hands-on experience in an optics lab;
• Preferable have some experience with numerical models;
• Have good communication skills in English (verbal and written).

Other requirements you need to meet:

• You are enrolled at an educational institute for the entire duration of the internship;
• If you are a non-EU citizen, studying in the Netherlands, your university is willing to sign the documents relevant for doing an internship (i.e., Nuffic agreement).

This position requires access to controlled technology, as defined in the United States Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
