In the fields of light manipulation and localization, quasiperiodic photonic crystals, or photonic quasicrystals (PQs), are causing an upsurge in research because of their rotational symmetry and long-range orientation of transverse lattice arrays, as they lack translational symmetry. It allows for the optimization of well-established light propagation properties and has introduced new guiding features. Therefore, as a class, quasiperiodic photonic crystal fibers, or photonic quasicrystal fibers (PQFs), are considered to add flexibility and richness to the optical properties of fibers and are expected to offer significant potential applications to optical fiber fields. In this review, the fundamental concept, working mechanisms, and invention history of PQFs are explained. Recent progress in optical property improvement and its novel applications in fields such as dispersion control, polarization-maintenance, supercontinuum generation, orbital angular momentum transmission, plasmon-based sensors and filters, and high nonlinearity and topological mode transmission, are then reviewed in detail. Bandgap-type air-guiding PQFs supporting low attenuation propagation and regulation of photonic density states of quasiperiodic cladding and in which light guidance is achieved by coherent Bragg scattering are also summarized. Finally, current challenges encountered in the guiding mechanisms and practical preparation techniques, as well as the prospects and research trends of PQFs, are also presented.

设计了一种应用于特定机载平台上的变焦距镜头。为了减小轴向尺寸,后镜组进行了2次折反,光学系统的轴向尺寸96 mm,满足了空间的要求。镜头变倍比为20倍,焦距6~120 mm,相对孔径1/5.6。采用了机械补偿方法和滑架导向机构。该镜头轴向尺寸小、精度高、变焦过程光轴晃动小。通过试验,检测出变焦过程光轴晃动不大于34″。通过飞行试验实现了短焦距搜索目标、长焦距跟踪目标的功能,并且变焦快速,像面稳定,视频跟踪图像清晰。

提出了一种同时基于全内反射和光子带隙效应两种导光机制的双芯光子晶体光纤(PCF),并采用全矢量有限元法对其耦合特性进行了分析。该种光子晶体光纤双芯间的耦合不同于基于单一导光机制的双芯光子晶体光纤,出现了超模交替截止、耦合长度存在极大值等现象,光纤两纤芯间高折射率柱的谐振在双芯间的耦合过程中起着重要的作用。通过改变光纤中空气孔的大小及间距可以显著改变光纤的耦合长度,而改变高折射率柱的折射率可对耦合长度极大值的位置进行调节。
