TL;DR: In this article, a new type of integrated optical sensor that performs sensing in a wide wavelength range corresponding to mid-infrared (mid-IR) spectrum is proposed and designed.

TL;DR: In this article, a three-dimensional finite-difference time-domain method is integrated with a machine learning algorithm in order to design a photonic structure, which is the smallest photonic lens for subwavelength focusing of light.

TL;DR: In this paper, a simple two-dimensional complex parity-time-symmetric photonic structure is proposed, which is described by a non-Hermitian potential but possesses real-valued eigenvalues.

TL;DR: A two-dimensional photonic crystal structure composed of constant dielectric radii with rectangular unit cells is deployed to enable even-to-odd mode conversion and to induce an asymmetric refractive index distribution.

TL;DR: In this article, a novel concept of polarization beam splitting with high polarization extinction ratio is proposed based on the polarization sensitive self-collimation feature of symmetry reduced photonic crystals, which utilizes selfcollimation mechanism and rotated isof-frequency contours arising due to the deliberately implemented symmetry reduction in the photonic structure.
