TL;DR: In this article, a 2D square lattice Photonic crystal (PhC) structure of dielectric rods embedded in air background is used to construct all-optical OR, AND, XOR, NOR, NAND and XNOR logic gates based on the interference effect.

TL;DR: This paper reviews the operation of photonic crystal logic gates and depicts the different design techniques that produce a wide range of structures realizing the logic functions, investigating several techniques such as self-collimated beam, multi-mode interference, interference based defect method and nonlinear Kerr materials based gates.

TL;DR: In this paper, a method for the systematic synthesis, design, and performance optimization of single-ended varactor-based 2:1 parametric frequency dividers (PFDs) exhibiting an ultralow power threshold was discussed.

TL;DR: A new chip-less and battery-less tag-based WSN that fundamentally breaks any previous paradigm, formed by off-the-shelf lumped components on a printed substrate, that can sense and transmit information without any need of supplied or harvested DC power, while enabling full-duplex transceiver designs for interrogating nodes rendering them immune to their own self-interference.

TL;DR: It is shown that it is finally possible to identify any items along the cold chain whose temperature has exceeded a remotely configurable Tth value as low as −47 °C, even if operating in uncontrolled electromagnetic environments and up to 46 m away from the corresponding PAST outside a line-of-sight.
