| 英文摘要 | An asymmetric double semiconductor quantum well is proposed to realize two-dimensional parity-lime (PT) symmetry and an electromagnetically induced grating. In such a nontrivial grating with PT symmetry, the incident probe photons can be diffracted to selected angles depending on the spatial relationship of the real and imaginary parts of the refractive index. Such results are due to the interference mechanism between the amplitude and phase of the grating and can be manipulated by the probe detuning, modulation amplitudes of the standing wave fields, and interaction length of the medium. Such a system may lead to new approaches of observing PT-symmety-related phenomena and has potential applications in photoelectric devices requiting asymmetric light transport using semiconductor quantum wells.
