We propose a novel approach to imaging in diffusive media based on time-resolved
reflectance measurements at null source-detector separation. This approach yields better …

The paper describes design and analysis of Tera Hertz Optical Asymmetric Demultiplexer
(TOAD) switch using quantum dot semiconductor optical amplifier (QDSOA) and all-optical …

This paper introduces the development of NOT, OR, and AND logic gates utilizing a 2: 1
Multiplexer (MUX) based on a titanium-diffused lithium niobate electro-optic Mach–Zehnder …

This paper demonstrates the structure and working principle of an optical 2-bit multiplier
using lithium niobate (LiNbO 3) based Mach–Zehnder interferometer (MZI). The powerful …

An all-optical arithmetic unit with the help of terahertz-optical-asymmetric-demultiplexer
(TOAD)-based tree architecture is proposed. We describe the all-optical arithmetic unit by …

A flip-flop (FF) is a kind of latch and the simplest form of memory device, which stores
various values either temporarily or permanently. Optical FF memories form a fundamental …

Science and Technology is providing people all over the world with much better ways of
communicating than ever before, and the winds of change have whipped up the de‐-sire to …

Galois field (GF) algebraic expressions have been found to be promising choices for
reversible and quantum implementation of multivalued logic. For the first time to our …

Logic gates are the fundamental building blocks of digital systems. Using these logic gates,
one can perform different logic and arithmetic operations. All-optical logic and arithmetic …

Symmetric ternary number (radix= 3) has three logical states (1¯, 0, 1). It is very much useful
in carry free arithmetical operation. Beside this, the logical operation using this type of …
