INTRODUCTION

The task of computing in modern day is done through a silicon computer. This silicon computer has done wonder for our own day-to-day life think about all the quality of life that we got thanks to this little technology from finding where we are in this blue marble, to safely safe us from life threatening condition like the inflation of airbag when a car crash to safe the passenger on the car.

While this silicon wonder beyond a doubt has made a miracle it is by no means without its own limitation & drawback, silicon has neared its own limitation such as the speed, heat generation and miniaturization. This tech blog will be looking into technology that potentially can change how modern computing will looks like.

• Graphene computer

Graphene computer as its name is using the graphene component for its logic gate instead of silicon why the graphene material is crucial? Because graphene able to clock much higher compared to silicon, graphene computer able to clock in hundred of gigahertz into even terahertz while silicon is only at single gigahertz the difference is 1000x much higher, on top of that graphen has a better interconnection offering lower resistance and higher speed data transfer compared to copper. Other wonders of graphene material also can be found in energy storage technology such as power bank a power bank made with graphene material has a higher speed charging times up to 5x compared to usual power bank with the same capacity and longer battery health life.

• Photonic computer

Photonic computer on the other hand works a little different, we can think it like how an optical cable work. Instead of using electron to transfer & communicate between the logic gate, photonic use light to transmit data. Light has a faster speed compared to electron, by utilizing this fact a computer using light has a faster transmit data, on top of that light itself can consist a lot of different wavelength at the same time in a single stream of light, using that we can encode data into different wavelength and send it in a single stream of light without interference and thus increasing the parallelism computing. Another quirk of photonic computer is that it can computed on the fly, unlike the classical computer which needed to stop the data transmit to calculated it, this means the speed of computation is in the realm of femto seconds. By utilizing all the characteristic of light, a photonic computer has a much higher ceiling contrast with classical computer.

CONCLUSION

The replacement of material on classical computer is a challenge that needed to be solved out if not the progression we enjoyed will be stuck unable to continue. This tech blog offer an alternate pathway on how we can revolutionize how a computing will work be it the graphene or photonic, or maybe in the future both of the technology will be used simultaneously.
