Plasmon-polariton gap and associated phenomenon of optical bistability in photonic hypercrystals

Spatial Dispersion in Hypercrystal Distributed Feedback Lasing

“…Despite increasing number of studies in the field of nonlocal metamaterials, the effect of spatial dispersion on optical properties of photonic hypercrystals has not been yet discussed. Photonic hypercrystals (PHCs) are a novel class of metamaterials combining properties of photonic crystals and hyperbolic media [ 20 ] and revealing interesting properties, such as difractionless imaging [ 21 ], optical bistability [ 22 ], cloaking [ 23 ], or tunable broadband unidirectional absorption [ 24 ]. Recently, it has also been demonstrated that tunable lasing with voltage-controllable single mode generation is also possible in this class of structure [ 25 ].…”

Distributed Feedback Laser Based on Tunable Photonic Hypercrystal

“…This class of structure, typically realized in the simple multilayer form, reveals unique dispersion properties that allow the obtaining of many practical functionalities, such as tunable spectral filters [ 11 ], perfect absorbers [ 12 ], and many others [ 13 , 14 , 15 , 16 , 17 , 18 ]. Since the pioneering work of Narimanov published in 2014 [ 10 ], the topic of photonic hypercrystals (PHCs) has been investigated both theoretically [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ] and experimentally [ 31 ]. It has been demonstrated that surface waves in a hypercrystal combine properties of Tamm states in the photonic crystal and surface plasmon polaritons at the metal–dielectric interface [ 10 , 30 ].…”

“…Moreover, studies in this field also uncovered that PHC structures reveal a remarkable potential for spontaneous emission enhancement combined with effective light outcoupling compared to hyperbolic metamaterials [ 33 , 34 ]. Unusual propagation properties of surface waves in hypercrystals have attracted widespread scientific attention [ 22 , 23 , 24 , 26 , 27 , 28 ]. To date, propagation of surface waves in hypercrystals has been considered in many different schemes, including propagation in the presence of an external magnetic field [ 22 ], various interfaces [ 26 ], and aperiodical PHC geometries [ 24 ] as well as when employing plasmon polariton gap to obtain optical bistability [ 27 ] or possibility to excite electrostatic waves [ 28 ].…”

“…In his work, Smolyaninov demonstrated that the level of nonlinearities achievable in photonic hypercrystals paves promising foundations for future applications in optical limiting and optical computing [ 25 ]. To date, the majority of presented works have been focused on slab (one-dimensional) hypercrystals [ 19 , 20 , 21 , 22 , 23 , 24 , 26 , 27 ], which are regarded as highly feasible. It has been reported that HPCs are able to operate over visible and infrared frequencies [ 35 ].…”
