Efficiently interfacing quantum emitters with optical fibers is a key challenge for quantum technologies. Coupling a single emitter to a one-dimensional waveguide enables efficient single photon sources and/or strong light-matter interactions at the single-photon level. Our group develops hybrid interfaces combining solid-state quantum emitters and tapered optical nanofibers: ultrathin fibers (~300 nm diameter, >98% transmission) that collect photons directly into a guided mode, offering a compact, low-loss, fiber-compatible platform. We are looking for someome to contribute to the development of a fully fiber-integrated quantum light source based on single quantum emitters. Depending on their interests, the project may focus on: enhancing emitter-waveguide coupling with hybrid photonic-plasmonic structures on nanofibers; characterizing single-photon emitters, including at cryogenic temperatures; quantum nonlinear optics and photon correlations in 1D waveguides; or nanoscale sensing (Raman spectroscopy, magnetic fields) with nanofiber evanescent fields. The student will receive hands-on training in experimental quantum optics: optical setups, nanofiber fabrication, spectroscopy, single-photon measurements, data analysis and simulations. We seek M2 students in physics, quantum optics, photonics or nanoscience with experience in experimental optics; Python or FDTD skills are a plus. The internship can lead to a PhD in our group.
