An optical analog to digital converter (OADC) comprises two main components: a nonlinear
demultiplexer and an optical encoder. The nonlinear multiplexer converts the continuous …

Today, one of the most important objectives concerned with integrated optical circuits is to
realize all-optical networks. High transmission speed and efficiency and no interference …

Half adder and half subtractor are the basic building blocks of an arithmetic logic unit used in
every optical central processing unit (CPU) to provide computational operators. In this paper …

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 report a new design of an all-optical filter using photonic crystal
microstructure. Ring resonators, line defects, scatterer rods, microcavities, and coupling rods …

This paper reports a new design of a broadband absorber composed of graphene, dielectric,
and gold layers. The designed absorber has four absorbent modes close to each other …

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 …

In view of the large scientific and technical interest in the MEMS accelerometer sensor and
the limitations of capacitive, resistive piezo, and piezoelectric methods, we focus on the …

In this paper we are going to propose and design an all optical full adder based on photonic
