A Superfast Computer? The First Processor That Uses Light For Communication
Short Bytes : As data transfer or communication in electronic devices and its various systems involves dependence on bandwidth and power density, researchers at MIT have come up with the unique idea of electro-photonic system. This 3 mm by 6 mm system has a bandwidth density of 300 gigabits/sec/sq mm and is about 10-50 times greater than current packaged electrical-only microprocessors. M icroprocessors which can be simply defined as “CPU on a single chip “, finds large and diverse application in the market varying from digital watches, mobile phones, washing machines, computers, traffic control systems and so on. However, these circuits mostly make use of electrical circuits for the purpose of communication and transfer of information. We already know that! Shannon’s Theorem gives an upper bound to the capacity of a link, in bits per second (bps), as a function of the available bandwidth and the signal-to-noise ratio(SNR) of the link. The Theorem c...
