Photonic quantum-well structures containing negative-index materials

The properties of photonic quantum-well structures containing negative-index materials are studied theoretically, showing features remarkably better than conventional photonic quantum-well structures. Owning to the zero- gap of one-dimensional photonic crystals containing negative-index materials, the photonic quantum-well structures can be proposed as a multiple channeled filter which is very weak dependent on incident angle and polarization, and insensitive to the thickness disorder of the barrier photonic crystals.
