Optical computing means performing calculations, operations, storage, and transmission of data using light instead of electricity. Instead of silicon chips, optical computers use organic polymers like phthalocyanine and polydiacetylene. Optical technology promises massive improvements in the efficiency and speed of computers, as well as a significant reduction in their size and cost. An optical desktop computer is capable of processing data up to 1,00,000 times faster than current models.

Advantage

– Optical computing is cheaper or more powerful than conventional computers. – Within a data path, multiple data sets can be transmitted in parallel at the same time using different wavelengths or polarizations. Data paths can cross each other without interference. – Superior speed of light allows extreme processing speeds. – Optical computers are said to work much faster than electronic computers

Disadvantages

– The development of its price is still expensive – Optical components can be built small and compact but not really miniaturized – Optical computers can use a different architecture. Therefore, these programs cannot use full optical computers: building a high-tech factory costs between several million and billions of dollars.

Comparison of optical computing with conventional computers

Optical computing

– Data paths can be crossed without interference – Based on two dimensions – High performance – The bottleneck could disappear – Less heat is released – Less noise – Change the shape and design – No matter the communication distance – Long communication scope is possible. the data rate is very high and there is no crosstalk

conventional computers

– Cross data paths are not possible – Based on three dimensions – Performance inferior to that of optical computing – A bottleneck could appear – Produce heat to a greater or lesser extent – Much noise. fans developed to reduce noise – Built as a rectangular box (desktop) or as a laptop – Communication depends on distance – Longer distances decrease practical transfer rate

Characteristics

– Wireless optical mouse: the maximum speed is the speed of light. – Massage your hand with infrared rays – Fast and stable temperature (at 45 +/- 1) to warm your hand – Safety material to avoid damaging the mouse component – High precision option – Plug and play, no driver required – Scroll no scroll bars – Optical tracking engine – Comfortable shape – Low power devices The mouse is designed for use by younger children and features a smaller form factor for easier grip. It also features a colorful design that will make your child more interested in using a computer. – The mouse itself has a capacity of up to 1 million clicks. The mouse features an 800 dpi optical tracking interface. Optical tracking is much more accurate than a mechanical ball mouse and is also less prone to mechanical failure.

Past research

Existing silicon technology would represent a potentially less expensive and more feasible way to mass-produce future-generation devices that would use both electrons and photons to process information, rather than just electrons as has been the case in the past.

Less than a year ago, he created laser light from electrical current on silicon by placing a layer of silicon.

Ongoing investigation

This research is based on the development of the silicon laser. Computer technology now relies on silicon electronics for data transmission. Researchers have used this platform to demonstrate electrically pumped lasers that emit 40 billion pulses of light per second. because light can move thousands of times faster through solid materials than electrons and can carry more information at a time, requiring less energy. The creation of optical components in silicon will lead to optoelectronic devices that can increase the amount and speed of data transmission in computer chips while using existing silicon technology. Optical chips based on silicon photonic crystals would include their reduced risk of overheating due to lower power requirements.
