Optical computing means performing calculations, operations, storage, and transmission of data using light instead of electricity. Instead of silicon chips, the optical computer uses organic polymers such as 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.


– Optical computers are cheaper or more powerful than conventional computers. – Within a data path, several data sets can be transmitted in parallel at the same time using different wavelengths or polarizations. data paths can cross each other without interference. – The superior speed of light allows for extreme processing speeds. – It is said that optical computers work much faster than electronic ones.


– Price evolution remains expensive – Optical components can be built small and compact but not miniaturized – Optical computers can use a different architecture. Therefore, these programs cannot use full optical computers: building a high-tech factory costs anywhere from several million to billions of dollars.

Comparison of optical computing with conventional computers

optical computing

– Data paths can cross each other without interference – Based on two dimensions – High performance – Bottleneck could disappear – Less heat is released – Less noise – Change shape and design – Communication distance does not matter – Communication long range 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 – Inferior performance than optical computing – A bottleneck could appear – Produces heat to a greater or lesser extent – Lots of noise. fans developed to reduce noise – Built as a rectangular box (desktop) or as a laptop – Communication is distance dependent – Practical transfer rate decreases over longer distances


– 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 – Energy Efficient Devices The mouse is designed for use by younger children and features a smaller form factor for an easier grip. It also features a colorful design that will make your child more interested in using a computer. – The mouse itself is rated for up to 1 million clicks. The mouse features an 800 dpi optical tracking interface. Optical tracking is much more accurate than a mechanical trackball, and it’s also less prone to mechanical failure.

past investigations

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

Less than a year ago, laser light was created 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 depends 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 once, while requiring less energy. Creating optical components in silicon will lead to optoelectronic devices that can increase the amount and speed of data transmission in computer chips by using existing silicon technology. Optical chips based on photonic crystals of silicon would include their lower risk of overheating due to lower power needs.
