![عکس صفحه اول مقاله: Omnidirectional and tunable symmetrical confined states in photonic quantum-well structures with single-negative materials Omnidirectional and tunable symmetrical confined states in photonic quantum-well structures with single-negative materials](/preview/png/852121.png)
The symmetrical confined states are found in photonic quantum-well structures with single-negative materials, in which the photonic barrier is based on the zero-effective-phase gap. The number and frequencies of the symmetrical confined states can be tuned by varying the period number and thicknesses of the well photonic crystal, respectively. Furthermore, the symmetrical confined states of the structures are less sensitive to the incident angle and polarization, compared with previous confined states of photonic quantum-well structures based on the Bragg or zero-average-index gap. The structures open a promising way to fabricate symmetrically tunable and omnidirectional multichannel filters for future dense wavelength division multiplexing applications.
