摘要：
The direct observation of dimensional resonances in wide parabolic quantum wells is reported. Using a grating-coupler technique, we are able to excite and detect these resonances without the mediation of a magnetic field. The ability to tune electrically the carrier density in the well and-though not independently-the shape of the confining potential, enables us to compare directly out results with those of a recent theoretical prediction.
