Quantum Electronics Approach to Optical Negative Index Metamaterials (NIMs): Homogeneous NIMs in the Solid State.

摘要

Based on modern advanced methods of Quantum Optics, we discuss here the possibility of achieving the negative index of refraction in a semiconductor with donor-like impurities. This approach is genuine microscopic, and uses, instead of Maxwell equations (homogeneous NIM designs), the Quantum Mechanical methods. This design requires several specially prepared laser beams, one probe beam and several support beams, with specific intensities, frequencies and polarizations. These laser beams pump energy levels and create the desirable density matrix elements of an interest, which, in their turn, produce coherent permeability and permittivity responses at frequency of the probe laser beam.
