Abstract In 1987, Yablonovitch and John proposed an artificial dielectric structure known as
Photonic crystals (PhCs) consisting of periodic and random variation of the refractive index …

The research field of photonic crystals (PhCs) remains active on a global scale. PhCs, which
are periodic optical nanostructures with the characteristics of excellent light field …

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 …

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 used the novel defective resonant cavities to design an eight-channel
