Abstract
In infrared transmission experiments through a two-dimensional electro n system with substantial lateral density modulation in an InAs quantu m well, we directly observe plasmon absorption without the mediating h elp of a surface metallic grating. The plasmon frequency is determined by the average density, and its strength by the amplitude of the dens ity modulation. It disperses in a magnetic field in predicted fashion.
