A half-subtractor is a digital circuit that subtracts two inputs and displays the result in two
outputs. Photonic crystals (PhCs) are used in optical circuits, including encoders …

In this paper, a novel interference-based nanostructure was designed and simulated to
realize an all-optical 2-bit reversible comparator by employing a novel technique. The plane …

Chip-scale fluorescence-based biomolecule sensing was demonstrated using polymer-
based micro-photonic circuits. The device components, including the optical waveguides …

In this paper, we propose an all-optical AND gate based on a hybrid nonlinear photonic
crystal ring resonator structure. The structure relies on a nonlinear photonic crystal ring …

The broad range of sexually transmitted viruses are infections generally attained through
uncertain sexual contact and can lead to serious health complications or may result in death …

In this paper, we design and simulate a two-dimensional photonic crystal-based high speed
