AbstractFibonacci fractal structures have been already studied. However, more special fractal structures could be beneficial in specific applications. In this paper, we create three variations of Fibonacci fractal photonic crystals as well as original structure, including: inverse Fibonacci fractal photonic crystal, mirror symmetry Fibonacci fractal photonic crystal (MSFFPC), and finally folded Fibonacci fractal photonic crystal.

AbstractIn this paper, we propose a heterostructure multichannel add/drop filter based on 2-D photonic crystal ring-resonator in which, add and drop operations are accomplished by coupling between two W1 waveguides. The wavelength spacing of 10.3 nm, as well as the average cross-talk of −37.5 dB, are the other features of the proposed filter. Furthermore, nanoscale […]
