We report a new configuration of all-optical logic gates based on two-dimensional (2D)
square lattice photonic crystals (PCs) composed of silicon (Si) rods in Silica (SiO 2). The …

The optical switching phenomena has been studied and its efficient application to construct
the full-adder/subtractor (A/S) has been projected. The paper constitutes the mathematical …

All optical frequency encoded logic gates XOR and XNOR are designed and simulated
using quantum dot semiconductor optical amplifiers (QDSOA) at 1 Tb/s for the first time as far …

Higher decimal numbers can be handled more efficiently using binary-coded decimal (BCD)
numbers than conventional binary numbers. In this study, we propose 4-bit full adder as well …

Ultracompact chip-integrated all-optical half-and full-adders are realized based on signal-
light induced plasmonic-nanocavity-modes shift in a planar plasmonic microstructure …

The long carrier lifetime of the semiconductor optical amplifier (SOA) limits its operation
speed and exploitation as ultrafast nonlinear switching element. Therefore, an alternative …

Ripple carry adders are broadly used for the addition of n-bit input sequences in arithmetic
and logic units and for performing packet-header processing in all optical packet switched …

Logic gates, as one of the most important basic units in electronic integrated circuits (EICs),
are also equally important in photonic integrated circuits (PICs). In this study, we proposed a …

We thoroughly explore the characteristics of an ultrafast all-optical NOR gate for 160 Gb/s
return-to-zero Gaussian data signals using a single quantum-dot semiconductor optical …

We have designed high-speed ultra-compact all-optical NOT and AND gates operating at
1550 nm on silicon-on-insulator (SOI) by a multi-objetice particle swarm optimized inverse …
