Has the era of photon computing arrived? What does the photonic chip bring to us?


What is an optic chip?

A photonic integrated Circuit (PIC) is an integrated circuit that integrates multiple photonic functions. This is similar to an electronic integrat circuit. Since 2012, hundreds of functions have been integrated into the single chip. Related researchers have combined the light emitting properties of indium-phosphide along with the optical routing capabilities and silicon into one hybrid chip. The light entering the silicon chip’s waveguide generates a continuous beam of laser light that can be used to drive other photonic devices.

The silicon-based laser technology will allow photonics to be used more widely in computers due to the large-scale silicon production technology that can greatly lower costs. Intel believes that the technology, although still far from commercialization is possible to integrate dozens, if not hundreds, of hybrid silicon lasers into a single silicon-based silicon chip. This will also allow for other components of silicon photonics in the future. This is the beginning for low-cost mass production and highly integrated silicon photonics chips.


How does the photonic circuit work?

Photonic integrated circuits make use of photons. These massless elementary particles represent light quantum, instead of electrons. Photons are free to move through the transmission medium with the speed of light, and are rarely impeded by other photons.

The human brain is interconnected and contains tens to billions of neurons. It also has high processing capabilities. Experiments show that supercomputers can accomplish the same amount as biological brains in just 40 minutes. The brain-like chip is a photonic chip that simulates the brain. It processes the data through the neural network framework, which simulates the brain using information carried by photons. As such, it can perform parallel high-speed and low-power calculations similar to the human brain. A combination of a micro-nano integrated photonic chip and a neural data processing system based upon optical computing is essential to achieving future information processing capabilities that are low in power, high speed, large data volumes, and very low power consumption.


Can the photonics Society replace electronics?

Each year we generate and use a lot data. But, the current technology that relies on electronic chip technology is at its limits. Heat is the limiter. This is due to the resistance created by electrons passing through the copper wires connecting many transistors on a chip. A new technology that does NOT generate heat is needed if we are to continue sending more data every year. Photonics uses light particles (photons) to transmit data.

How likely is that photonic-integrated circuits (PIC) will totally replace electronic integrated systems in the next 50 year? Jacob VanWagoner, Razvan Baba both mentioned that photonic integrated Circuits (PIC), cannot replace all electronic circuits.

Photons have no resistance, unlike electrons. Photons have no mass and charge so they scatter less heat in the materials they pass through. Energy consumption will therefore be decreased. Furthermore, by substituting electrical communication within a chip for optical communication, communication speeds between chips can be increased up to 1,000 times. Because the data center is able to transmit faster and use less cooling energy, it will reap the greatest benefits. These photonic chips will be useful for new applications.


What is silicon photography?

Silicon photonics (or silicon photonics) is a rapidly evolving technology where data is transmitted through light between computer chips. Light transmits more data per second than electric conductors. This technology uses laser light for data transmission into light pulses.

Silicon luminescence is the “Holy Grail,” of the microelectronics sector for decades. The solution to this problem will change computing forever, as chips will become faster than ever. Researchers at Eindhoven University of Technology are proud to have created a silicon alloy capable of emitting light. Now, the team will create silicon lasers which can be integrated into existing chips.


How does silicon photonics function?

This technology is called silicon photonics and uses silicon semiconductors for optical signals. It is faster than traditional electronic-based silicon devices and can therefore transmit digital signals more efficiently. In order to convert the light into light pulses using photons, they must be modulated.

Silicon photonics technology is a way for photonics, an information carrier, to reach the safety and reliability in signal transmission. It is a revolutionary, forward-looking technology with a strategic outlook. Silicon-optical integration uses light to replace original electricity for transmission to reduce the cost. The global silicon photonics industry is on the rise. This technology will be used for data communications, biochemical medicines, autonomous driving and national defense and security in future. Silicon photonics technology is quickly becoming the darling in capital markets.


Status of the development status for the photonic chips


The experimental photonic chip is capable of reaching crazy 44 TB internet speed

Australia’s research team recorded the fastest Internet speed, reaching 44.2 megabits/second with one light source speed. This is 44,000x faster than the fastest internet connections available to consumers. This feat was possible thanks to a new optical chip.

The Monash, Swinburne, RMIT universities researchers tested the technology using 76.6 km (47.6 mile) of optical fiber between two Melbourne universities.

Data can be transmitted at speeds of up to 44.2 Tbps within the bandwidth of 4THz. It is difficult to overstate the speed of it. Google Fiber offers the fastest Internet speed at just 1 Gb/s. The US Department of Energy’s dedicated scientific network ESnet offers a maximum speed of 400 GB/s. However, this speed is reserved for NASA.

Arnan Mitchel, the lead researcher for the study, stated: “In the longer term, we want to develop integrated photonic chip that can achieve this data speed over existing fiber links at minimal cost.” “Originally, they were intended for data. High-speed communication between central centers will be appealing. This technology will be affordable enough to be used commercially in cities around the globe, however.


New photonic chips could bring quantum computers to everyone

Everyone desires speed. We don’t want computers and mobile phones to slowdown. Although ultrafast quantum computers can and will break this, we still need a reliable source of entangled pair photon pairs to help us transmit and modify information. We can achieve this goal with a 100-fold increase efficiency. Furthermore, large-scale integrated quantum devices are within our reach.

The Stevens Institute of Technology was able to accomplish this remarkable feat. The creation of photon pairs requires the careful capture of light in an engraved microcavity nanoscale. Photon pairs are formed when light is reflected from the cavity. This seems like a simple process, but it is not.

According to the current technology, such a system needs a large amount incident laser light. The light must contain approximately hundreds of million photons to guarantee a pair. Stevens, Huang, and others developed another method based on a chip source of photons. This is capable of producing tens to millions of pairs per second using a single microwatt-powered beam of laser light. . These cavities are racetrack-shaped and reflect photons of very low energy. The light can circulate for longer periods of time, increasing efficiency.

This is certainly possible. The team is constantly improving its technology and finding new ways to make use of this photon source to drive quantum components and logic gates. They plan to add optical components to increase the technology’s scale, as it is based on chips. It is their ultimate goal to make quantum devices more efficient and less expensive so they can be integrated into other electronic devices. He hopes that our children will have quantum laptops.
