Fig. 1: Schematic of the planar photonic chip and its photonic band gaps. a The photonic chips composed of three parts, the bottom (29 pairs of SiO2 + SiNx in total), top multilayer (10 pairs of SiO2 + SiNx in total), and the scattering layer (doped with TiO2 nanoparticles)...
1D PhC stacks have an angular photonic band gap for p-polarized light and half wave plates can convert s-polarized light to p-polarized light. By introducing alternating 1D PhC stacks and half wave plates, we predict that one can achieve a central transmission angle at normal incidence and ...
The photonic band gaps (PBGs) [33], [34] features are also possible for the generation of an angle window independent of the polarization, however, its angle selection stubbornly starts from 0 degrees and lacks tunability. In 2014, Shen et al. [35] proposed to use the Brewster angle ...

a non-reciprocal device comprises a photonic crystal comprising an array of dielectric rods. The non-reciprocal device further comprises three gaps in the array of dielectric rods, where light is localized in each of the three gaps in a frequency range for the gap thereby causing each of the ...
so a quantum interface to bridge the wavelength gap is necessary. So far, such an interface for OAM-carried light has not been realized yet. Here, we report the first experimental realization of a quantum interface for a heralded single photon carrying OAM using a nonlinear crystal in an opti...
In order to reduce the loss of the designed fiber, possible solutions might be considered: 1) using low-loss materials while optimizing the geometric structure parameters7,27; 2) using similar photonic crystal fiber structure to confine light in the air gap region to reduce the loss30. Methods...
