Internship: Fiber characterization for future QPU generations - W/M

Participate in the rapid development of a deep-tech start-up at the forefront of the second quantum revolution!

About Pasqal

PASQAL designs and develops Quantum Processing Units (QPUs) and associated software tools.
Our innovative technology enables us to address use cases that are currently beyond the reach of the most powerful supercomputers; these cases can concern industrial application challenges as well as fundamental science needs.
In addition to the exceptional computing power they provide, QPUs are highly energy efficient and will contribute to a significant reduction in the carbon footprint of the HPC industry.


Job Description

As part of our research effort on optical fibers, we are looking for a second year intern to join our Optics and laser systems team.

Objective of the internship: Characterize different types of fibers (FC/APC, endcap, PCF, etc.) at various wavelengths and output laser power for our future QPU generation.

The internship will consist of the following tasks:

  • Learn the principle of optical fiber and their different types
  • Learn to manipulate optical fibers, identify damages on the fiber’s surface and polish an optical fiber
  • Learn to couple laser outputs into optical fibers (learn to inject the light using a fiber dock in some cases and using optics to guide the light in free space in other cases).
  • Measure the polarization extinction ratio (PER) of the light inside optical fibers
  • Measure the Stimulated Brillouin Scattering (SBS) threshold of an optical fiber
  • Measure the Relative Intensity Nosie (RIN) of a laser to characterize the behavior of light inside the fiber
  • Do all the above using different types and characteristics of optical fibers
  • Present and summarize results in a clear test report, with good analysis of the observations

About you

Your are a second year engineering school student looking for a 4 months internship.
