He is the Director Emeritus at the Max Planck Institute for the Science of Light and an adjunct professor in the physics department at the University of Ottawa.

From 1980-1981, Leuchs served as a visiting fellow for the Joint Institute for Laboratory Astrophysics (JILA) in Boulder, Colorado.

[2] From 1985-1989, Leuchs served as the head of the gravitational wave group at the Max Planck Institute of Quantum Optics.

[5][6] The electromagnetic field produced by the tightly focused light can be used to manipulate atoms or other small-scale objects.

The correcting code, based on linear optics, protects against the loss of photons for quantum information processing.
