“…PhCs not only decorate nature brilliantly but also provide a powerful means to manipulate and control the propagation of light. For example, PhCs with complete band gaps, which serve as light semiconductors, are highly desirable in controlling and manipulating light [6][7][8]. Thanks to the Bloch band theory for the periodic systems, the photonic band structure can be designed and tuned conveniently, making PhCs a key platform for studying a broad spectrum of energy band-related physics [9].…”

Topological photonics is an emergent field at the cross of photonics and topological physics which opens our eyes to novel topological phenomena and versatile photonic effects. Photonic crystals (PhCs) are the optical analogs of conventional crystals that have proven to be an excellent photonic platform to explore topological physics. Here, we present a brief review of the all-dielectric topological PhCs by focusing on several prominent milestones of topological phases, such as the Su-Schrieffer–Heeger model, topological insulators, topological semimetals, and higher order topological phases. For each topological phase, the topological invariants and the intriguing topological properties as well as the potential applications are discussed. We conclude with the current challenge and the prospect of all-dielectric topological PhCs.

“…With the inspiration of optomechanical crystals, phoxonic crystals (PxC), which combine both capabilities of the PtCs and PnCs have attracted considerable attention in recent years. Designed PxCs can exhibit optical band gaps and acoustic band gaps in one structure to simultaneously control optical waves and acoustic waves [11][12][13][14][15][16][17][18][19][20]. Thus, PxCs have become an advanced structure for acousto-optic (AO) interaction studies [21][22][23][24][25][26].…”

We investigated the strength of acousto-optical (AO) interaction in one-dimensional fishbone silicon nanobeam computationally. The structure can generate phononic and photonic band gaps simultaneously. We use defect cavity optical mode and slow light mode to interact with acoustic defect modes. The AO coupling rates are obtained by adding the optical frequency shifts, which result from photo-elastic effect and moving-boundary effect disturbances. The AO coupling rates are strongly dependent on the overlap of acoustic and optical mode distribution. The strength of AO interaction can be enhanced by choosing certain acoustic defect modes that are formed by the stretching of wings and that overlap significantly with optical fields.

“…Since then, the concept of nontrivial topological physics has been introduced to classical systems, such as topological acoustic [5][6][7], and elastic waves systems [8][9][10], with particular interests focusing on achieving one-way protected edge states that are immune to backscattering. In recent years, photonic equivalents of condensed matter topological insulator (TIs) have led to unprecedented opportunities in the control of EM waves [11][12][13][14][15], and a variety of theoretical and experimental demonstrations have been reported from microwaves to optical waves [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Whereas, previous realizations of photonic topological states relied on external magnetic fields to emulate the quantum Hall effect, with the use of time-reversal symmetry breaking [16][17][18][19][20].…”

Reconfigurable Topological Phases in Two-Dimensional Dielectric Photonic Crystals

The extensive research on photonic topological insulators has opened up an intriguing way to control electromagnetic (EM) waves. In this work, we numerically demonstrate reconfigurable microwave photon analogues of topological insulator (TIs) in a triangular lattice of elliptical cylinders, according to the theory of topological defects. Multiple topological transitions between the trivial and nontrivial photonic phases can be realized by inhomogeneously changing the ellipse orientation, without altering the lattice structure. Topological protection of the edge states and reconfigurable topological one-way propagation at microwave frequencies, are further verified. Our approach provides a new route towards freely steering light propagations in dielectric photonic crystals (PCs), which has potential applications in the areas of topological signal processing and sensing.
