In recent decades, the demand for computational power has surged, particularly with the
rapid expansion of artificial intelligence (AI). As we navigate the post-Moore's law era, the …

In this review, a comprehensive summary on photonic crystal based all-optical logic decoder
reported in the last decade has been made. The articles reviewed are primarily grouped into …

In this paper, we proposed a novel all optical analog-to-digital (ADC) converter based on
photonic crystals. First of all, we designed a three port nonlinear demultiplexer, for producing …

A novel design for realizing all optical analog to digital converter will be proposed in this
paper. The proposed structure consists of two main parts; a nonlinear 3-channel …

A comparator is one of the important combinational logic circuits. An optical comparator was
designed and simulated based on photonic crystals. Point and linear defects were also used …

In this study, an all optical 4‐to‐2 encoder have been proposed which has four input and
three output ports. The proposed structure can generate a 2‐bit binary code considering …

We propose an all optical 1-bit comparator design based on the two dimensional (2D)
photonic crystal ring resonator (PhCRR) coupled to six optical waveguides. The two …

In this paper, we are going to propose and design an all optical half adder based on
photonic crystal structures. For realizing the proposed structure, we will use two nonlinear …

In this paper, we propose what we believe is a novel all-optical analog-to-digital converter
(ADC) based on photonic crystals. The proposed structure is composed of a nonlinear …

In view of the large scientific and technical interest in the frequency-selective all-optical
devices, and some optical filters limitations, we focus on the design and analysis of a novel …
