FLAT PASS-BANDS OF ONE-DIMENSIONAL PHOTONIC CRYSTALS COMPOSED OF MULTIPLE QUANTUM WELLS WITH GAUSSIAN-DISTRIBUTED REFRACTIVE INDICES

Transmissions of one-dimensional (1D) photonic crystals (PCs) containing multiple quantum wells with Gaussian-distributed refractive indices are calculated with the use of the transfer-matrix method. The transmission spectrum of this kind of structures exhibits flatted pass-bands. The resonant peaks in the transmission spectrum of the conventional 1D PCs have been significantly suppressed. It is expected that this kind of structures may favor the fabrication of optical filters in applications to micro-optical devices.

The transmission spectrum of symmetrically structured one-dimensional photonic crystal (AB)m(BA)m consisting of positive and negative materials was studied with transfer matrix method theory. The result shows that a single narrow transmission peak constantly appears at the frequency of uneven ω/ω0, while a broad transmission peak appears at the frequency of even ω/ω0. When periodicity m or refractive index nA of Layer A increase, the narrow transmission peaks in the spectrum become sharper and the broad peaks become narrower; as refractive index nB of Layer B rises, all the peaks in the spectrum become broader; and when the thickness dA of Layer A medium thicken, the transmitting peaks move towards alto frequency,while with the thickening of dB of Layer B medium, these peaks move inversely towards low frequency. Furthermore, in these two circumstances, the transmitting peaks at right alto frequency move faster; however, peaks remain unchanged when both dA and dB concurrently thicken. All these optical transmission characteristics of symmetrically structured one-dimensional photonic crystals can offer guidance to designing adjustable super-narrow optical filters, broad band filters and optical switches.
