We have observed the suppression of Fano resonances in epitaxial layers of GaAs in a magnetic field due to discretization of the quasi-continuum by quantum confinement. Our observations can be explained using a simple “picket fence” model in which the density of states can be adjusted to model the different thickness epitaxial layers. The suppression of the Fano resonance occurs for length scales which are unusually large for optical experiments.
