TL;DR: In this article, a phase change material, Ge2Sb2Te5 (GST), was integrated with silicon microring resonators to demonstrate an energy-efficient, compact, non-volatile, reprogrammable platform.

TL;DR: In this paper, an optical equivalent of the field-programmable gate array (FPGA) is proposed for large-scale photonic integrated circuits (PPGI) devices.

TL;DR: An ultracompact and low-loss TM-pass polarizer on silicon is proposed and demonstrated experimentally with a subwavelength-grating (SWG) waveguide to support Bloch mode for TM polarization.

TL;DR: In this article, with phase transitions actuated by in situ silicon PIN diode heaters, scalable nonvolatile electrically reconfigurable photonic switches using PCM-clad silicon waveguides and microring resonators are demonstrated.

TL;DR: In this article, the authors proposed a thin artificial structure that could give rise to the strong reduction of both radar wave reflection and infrared thermal emission, realized by the subtle combination of two specifically designed metasurface layers that control the infrared emission and microwave absorption, respectively.
