photonic processor
what happen if we process the data in the form of light itself ?
what is photonic processor ?
what if the data processing speed is almost equal to the speed of the light ?
lets find answers of these questions .
before knowing about the photonic processor, first we try to know the traditional data transferring.
copper wire used for communication
copper is a good conductor of electricity. in olden days people used copper for communication because the copper have the free electrons, when we apply potential difference between the two end of copper wire we gradually see the flow of electrons from one end to other end but there are many disadvantages in copper. when the length of the wire increases the efficiency and strength will decrease. cost also increase by using copper in electronics appliance communication
optical fiber communication
the optical fiber communication work on the principal of total internal reflection. when we observe the light spectrum 'red' and 'blue' lights travel longer distance because of higher wavelength. in communications the electronic devices at transmitter side the data 0s and 1s of electrical data converted into optical energy in the form of light pluses.
these light pluses can be transferred into electronic signals (0s and 1s) at receiving end these signals processed by the processor which is made of transistor, and transistor act like a switch how much the speed of switching will be as much the speed of processor performance increases. because of this most of the communications uses the optical fiber cables. we can also send multiple data by using multiple colors(red, blue) in single optical fire cable
there are many advantages by using the optical fiber cable ,higher efficiency, less distortion and so on
photonic processor
As we seen early that in electronic system at transmitting side electrical energy converted into optical energy and at receiving side same optical signal converted into electrical signal for processing the data..
the photonic processor work on the principle of superposition theorem. the photonic processor which used to process the signal as in the form of light without converting into electrical energy .we know that the speed of light is 3,00,000 m/s so it is 3000 times faster the performances as of now faster the switching time we obtain, faster performances for processing the data.
there is an important aspect called latency, latency is defined as the information have to move from one transistor to other transistors for processing of data .
hp company demonstrated a basic logic gate by using the photonic processor so this technology will be available in coming 20 to 30 years in future.
