Description of the Team/Project

This internship offers you the opportunity to join a team dedicated to designing and developing ultra-bright single-photon sources. The project focuses on fabricating innovative optical cavity designs for next-generation single-photon sources. As an intern, you will work in the C2N and IPVF cleanrooms, assisting the team in developing new fabrication recipes for micro-cavities. Your contributions will directly influence the research strategy for next-generation devices and advance the field of single-photon sources. Candidates should have a fundamental understanding of nano/micro processing techniques such as thin-film deposition, lithography, and etching. Experience in electrical, mechanical, or optical characterization of nano- or micro-devices is also desirable. Candidates may commence the internship starting in February, with flexible start dates available thereafter to accommodate individual circumstances.

Your Key Responsibilities

• Conceptualize and perform numerical simulations of the mechanical and optical properties of micro-cavities. 

• Develop and refine fabrication recipes for constructing high-performance cavities. 

• Identify critical fabrication steps that influence device performance and propose improvements. 

• Design, assemble, and operate custom experimental setups for device characterization. 

• Maintain systematic documentation of findings and report results effectively.

• You are enrolled in a university program that includes an internship period. This should be a Master's Degree (first or second year) or equivalent (not a PhD) program in Physics, Engineering, or related fields
• You are available full-time for 5 to 6 months
• You have background in physics, micro-engineering, optics or a related discipline
• You want to work in an international team and have good English communication skills
• You are curious, energetic, and love solving problems
• Experience with Python is a plus

• Swile Card (meal vouchers) 🍴🛒

• 50% participation in transportation costs 🚆

• Possibility of remote work 💻
• Internship Allowance between €1,200 and €1,400 per month 💰

• 1,5 days off per month, cumulative 🧳
