“…In recent years, complex photonic crystals (PCs) have provided a new opportunity to explore the non-Hermitian optical properties and other nonlinearities theoretically and experimentally [22][23][24][25][26][27][28]. Many significant optical characteristics have been discovered in PCs, such as solitons [29][30][31][32][33], topological modes [34,35], and strong absorptions [36][37][38][39].…”

We explored exceptional points (EPs) in one dimensional non-Hermitian photonic crystals incorporated with a defect. The defect was asymmetric with respect to the center. Two EPs could be derived by modulating the normalized frequency and the gain-loss coefficient of defect. The reflection coefficient complex phase changed dramatically around EPs, and the change in complex phase was π at EPs. The electric field of EPs was mainly restricted to the defect, which can induce a giant Goos–Hänchen (GH) shift. Moreover, we found a coherent perfect absorption-laser point (CPA-LP) in the structure. A giant GH shift also existed around the CPA-LP. The study may have found applications in highly sensitive sensors.

“…What is more, we can achieve specific optical functions by synthesizing PCs. PCs can also realize localization of light field [5][6][7][8], unidirectional transmission [9,10], directional cloaking [11], solitons [12][13][14], and other functions [15][16][17][18][19]. Otherwise, PCs are used to control photon flows, which can realize the miniaturization and integration of photonic devices [20][21][22][23][24].…”

Coherent Perfect Absorption Laser Points in One-Dimensional Anti-Parity–Time-Symmetric Photonic Crystals

et al. 2019

We investigate the coherent perfect absorption laser points (CPA-LPs) in anti-parity–time-symmetric photonic crystals. CPA-LPs, which correspond to the poles of reflection and transmission, can be found in the parameter space composed of gain–loss factor and angular frequency. Discrete exceptional points (EPs) split as the gain–loss factor increases. The CPA-LPs sandwiched between the EPs are proved to be defective modes. The localization of light field and the bulk effect of gain/loss in materials induce a sharp change in phase of the reflection coefficient near the CPA-LPs. Consequently, a large spatial Goos–Hänchen shift, which is proportional to the slope of phase, can be achieved around the CPA-LPs. The study may find great applications in highly sensitive sensors.

“…In addition, the nonlocal nonlinearity effect is considered as one of an important effect in nonlinear optics for that it has some unique interesting characteristics, such as supporting the propagation of multipole solitons [18], and suppressing the collapse of (1+2)-dimensional soliton [19], etc. Hence, various novel solitons, such as Hermite-Gaussian solution [20], complicated structure soliton [21], gap soliton [22], spatiotemporal soliton cluster [23], variable sinh-Gaussian soliton [24], ring dark and antidark solitons [25], etc, all can form in nonlocal nonlinear media.…”

This paper obtains the numerical solutions of the elliptic solitons in a (1+2)dimensional anisotropic nonlocal nonlinear fractional Schrödinger equation, and verifies their stabilities by the direct propagation method. The results show that the properties of such solitons relatively depend on the Lévy index. Such as the soliton shape varies with the change of Lévy index. When the Lévy index decreases, the ellipticity will increase, while the critical power will decrease. Furthermore, we demonstrate the physical features exhibited by the higher order elliptic solitons for a different Lévy index.
