*Adders are digital circuits that carry out addition of numbers. Adders are a key component of Arithmetic Logic unit. Apart from addition, adders are also used in certain digital applications like table index calculation, address decoding etc.*

*An adder is digital circuit that perform addition of numbers. In modern computer adder resides in the arithmetic logic unit ALU. There are two types of Adder:.*

In this article, half-adder and full-adder gates are implemented by using the structure of photonic crystals and the results are expressed. It should be noted that finally, an improved structure was presented. The proposed plasmonic structure permits TM mode to propagate in it and therefore, it is possible to minimize the size of structure to the nanoscale.

## Half Adder and Full Adder

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 covered with a nonlinear nanocomposite layer, which can be directly integrated into plasmonic circuits. Tremendous nonlinear enhancement is obtained for the nanocomposite cover layer, attributed to resonant excitation, slow light effect, as well as field enhancement effect provided by the plasmonic nanocavity. Our work is the first to experimentally realize on-chip half- and full-adders based on nonlinear plasmonic nanocavities having an ultrasmall feature size, ultralow threshold power, and high intensity contrast ratio simultaneously. This work not only provides a platform for the study of nonlinear optics, but also paves a way to realize ultrahigh-speed signal computing chips. Nowadays, optical computing which uses photons as information carriers has attracted enormous attention, as it has the ability to support ultrahigh-speed and ultrawide-band information processing [ 1 ].

An Adder is a device that can add two binary digits. It is a type of digital circuit that performs the operation of additions of two number. It is mainly designed for the addition of binary number, but they can be used in various other applications like binary code decimal, address decoding, table index calculation, etc. There are two types of Adder. One is Half Adder , and another one is known as Full Adder.

## Half Adder and Full Adder Circuit

These circuits have some characteristics like the output of this circuit mainly depends on the levels which are there at input terminals at any time. Some of the combinational circuits are half adder and full adder, subtractor, encoder, decoder, multiplexer, and demultiplexer. An adder is a digital logic circuit in electronics that is extensively used for the addition of numbers. In many computers and other types of processors, adders are even used to calculate addresses and related activities and calculate table indices in the ALU and even utilized in other parts of the processors. These can be built for many numerical representations like excess-3 or binary coded decimal.

Half Adder and Full Adder circuits is explained with their truth tables in this article. Design of Full Adder using Half Adder circuit is also shown. Before going into this subject, it is very important to know about Boolean Logic and Logic Gates. An adder is a kind of calculator that is used to add two binary numbers. There are two kinds of adders;.

- Не больница, а помойка. И они еще решили оставить меня здесь на ночь. Беккер огляделся: - Понимаю. Это ужасно.

*Попытался что-то сказать, но голоса не. Зато был другой голос, тот, что звал .*

Но того человека в очках нигде не. Были другие люди. Празднично одетые испанцы выходили из дверей и ворот на улицу, оживленно разговаривая и смеясь. Халохот, спустившись вниз по улочке, смачно выругался.

Уже два часа утра. - Pi'dame uno. Вызовите мне машину.

*Где это? - Где же на необъятных американских просторах прячется эта загадочная Северная Дакота. - Где-то поблизости от Вашингтона, округ Колумбия, сэр.*
