“…This situation introduces a mismatch between computer based design capability of 3D aperiodic patterns and their fabrication capability. To overcome this mismatch, two useful methods have recently been introduced, namely laser holographic lithography and direct-laser-writing techniques [173]. In particular, laser holographic lithography relies on the interference of several coherent laser beams to produce a pattern that is recorded (due to photoinduced polymerization) in a photoresist material template.…”

In this work we consider the role of aperiodic order-order without periodicity-in the design of different optical devices in one, two and three dimensions. To this end, we will first study devices based on aperiodic multilayered structures. In many instances the recourse to Fibonacci, Thue-Morse or fractal arrangements of layers results in improved optical properties compared with their periodic counterparts. On this basis, the possibility of constructing optical devices based on a modular design of the multilayered structure, where periodic and quasiperiodic subunits are properly mixed, is analyzed, illustrating how this additional degree of freedom enhances the optical performance in some specific applications. This line of thought can be naturally extended to aperiodic arrangements of optical elements, such as nanospheres or dielectric rods in the plane, as well as to three-dimensional photonic quasicrystals based on polymer materials. In this way, plentiful possibilities for new tailored materials naturally appear, generally following suitable optimization algorithms. Then, we present a detailed discussion on the physical properties supporting the preferential use of aperiodic devices in a number of optical applications, opening new avenues for technological innovation. Finally we suggest some related emerging topics that deserve some attention in the years to come.

“…The interest in PtC and PnC is to control the flow of electromagnetic and mechanical waves, respectively. Since the discovery of PtC, a fundamental milestone has been to find a structure with a complete band gap for all the directions of the space [4,5]. The limiting factor to obtain a wide photonic band gap is the contrast of the materials, higher the contrast biggest the band gap.…”

In this work we present experimental evidence of the enlargement of the non-transmission range in one-dimensional phononic crystal heterostructures. Heterostructures are composed by a tandem of different phononic crystal lattices. The constituent phononic crystal lattices have been properly chosen so that their band gaps overlap each other to obtain a giant stop band. Heterostructures consisting of a periodic arrangement of aluminum and epoxy layers were fabricated and characterized. We have designed giant stop bands in the range of MHz obtaining a good agreement between theoretical and experimental results.

“…[9] Additionally, even with the most recent experimental techniques it has only been possible to fabricate 3D structures with a low variation in the refractive index, typically n < 2.0. [7] This low index contrast attained in 3D PCs is a limiting factor in some applications in telecoms or near infrared range where a large range of band gap is required. [10,11] To obtain wider PBG it is desirable to increase the refractive index, different authors have reported that the width of the band gap is a function of the contrast index, the larger the better.…”

In this work we show theoretically that it is possible to design a large band gap in the infrared range using a one-dimensional Photonic Crystal heterostructure made of porous silicon. Stacking together multiple photonic crystal substructures of the same contrast index , but of different lattice periods, it is possible to broad the narrow forbidden band gap that can be reached by the low contrast index of the porous silicon multilayers. The main idea in this work is that we can construct a Giant Photonic Band Gap -as large as desired-by combining a tandem of photonic crystals substructures by using a simple analytical rule to determine the period of each substructure.
