Progress in develo** photonic chip based optical processing devices with ultrahigh‐
bandwidth is reviewed. The unprecedented processing bandwidth of our platform based on …

To achieve complete security of communication, there is a need for “real-time” ultrafast
physical random bit generators (RBGs). In the available physical RBGs, random bit …

In recent years, architectures, devices, and components in telecommunication networks
have been challenged by evolutionary and revolutionary factors which are drastically …

Doppler reflectometry spatial and wavenumber resolution is analysed within the framework
of the linear Born approximation in the slab plasma model. An explicit expression for its …

An N bit all-optical comparator and an all-optical full adder are presented. These complex
circuits, which perform photonic digital processing, are implemented cascading a unique …

We report on the simultaneous wavelength conversion operation of a dual-element
semiconductor optical amplifier-Mach–Zehnder interferometer (SOA-MZI) array hybridly …

Photon being the ultimate unit of information with unmatched speed and with data package
in a signal of zero mass, the techniques of computing with light may provide a way out of the …

Basic configurations of various all-optical clocked flip-flops (FFs) and optical random access
memory (RAM) based on the nonlinear polarization rotation (NPR) effect of low-polarization …

We propose a real-time self-balanced photonic method for extracting ultrafast random
numbers from broadband randomness sources. In place of electronic analog-to-digital …

An all-optical two 2-bit numbers multiplication with the help of Semiconductor Optical
Amplifier (SOA)—assisted Sagnac Switch is proposed and described. The paper describes …
