As computer enthusiasts, we are always on the lookout for the latest and greatest technology. So what could be more exciting than the potential of photonic chips? These chips could revolutionize computing as we know it, making devices faster and more efficient. Keep your eyes peeled for developments in this area – the future of computing is looking very bright!
Generic processor produce too much heat. To solve this problem, we are going to have to find a new way to process information. Photonic computer chips may be the answer.
A photonic processor is a computer processor that uses light instead of electricity to perform calculations. Photonic processor speed will be much faster and more efficient than traditional processors, and has the potential to revolutionize the way we compute.
Facts About Photonic Computer Chips
What will the computer of the future look like for the past few decades? We have seen conventional computing meet the demands of everyday applications. It is true that silicon transistors have only gotten smaller over the years.
However a single silicon atom is 0.3 nanometers. So, there is definitely a limitation to how small a transistor can get concurrently.
These types of chips also have severe drawbacks when it comes to ai modeling 10 years ago. The biggest models were around 10 million parameters and could easily be trained in a few days on a single gpu.
Today, there are some models that are over 10 trillion parameters and in turn taking thousands of machines to train things, like automated cars speech recognition and even car assistance are highly dependent on machine learning. So there is a big drive to develop a different type of computing architecture.
One of the front runners is photonic computing. there are multiple startup companies looking at different problems in which these chips can solve but generally there are magnitude improvements in terms of speed and energy consumption. This new processor is called a lightmatter photonic processor, and it has the potential to revolutionize the way we process information.
One notable chip is the pace by light intelligence. It has ten thousand photonic devices on one chip running at one gigahertz. the core of the pace is an integrated silicon photonics chip, which combines digital and analog signals, photo detectors turn optical intensities into electric current. And this entire configuration is mounted on a pci board.
So it's not entirely a photonic computer chips but this is a stepping stone which will likely be taken by many startup companies and this means that the photonic chips can also be built through existing semiconductor fabrication techniques.
Ultimately the pace can tackle max cut problems 100 times faster than a high end gpu. The max cut is one of the simplest graph partitioning problems to conceptualize.
Another really neat development is lightmatters chips. So there's a lot of skepticism on how many optical components you can integrate on a circuit. So they're developing a chip, which can handle different wavelengths at the same time without losing coherence.
it would be interesting to see how many different wavelengths can be simultaneously running in the same hardware but this could be an answer to the scalability problem. Their chip will eventually act as a central unit which will power an autonomous ev.
Another really infamous computer we hear a lot about is the quantum computer but the fact still remains. That qubits are extremely hard to isolate, decoherence is inevitable and errors. eventually creep in having said that it basically is meaningless to have all these q bits without proper air correction.
We do have quantum annealers such as d-wave which can solve optimization problems but you always need to translate it into a cubo model. So it's a little bit problematic where a real quantum computer can implement any quantum algorithm keeping this in mind.
There are some companies which claim to be able to tackle this quantum problem by utilizing squeeze states of light and it's basically a programmable system of entangled photons.
How Photonic Processor Works?
The chip turns photons into squeeze states after the interferometer performs operations on the squeeze states. The photons leave the chip where external detectors perform the readout. For now the photon detectors have to be cryogenically cooled but the company claims that they have the framework for million qubit machines in the end. We do have a few photonic computer chips which are basically an experimental phase but we still have a big problem.
DNA storage could be a possible alternative as it can be encoded as four bases instead of zero or one. In theory dna drives could produce exabyte scales or one billion gigabytes but the problem is is that these are very difficult to scale up and control.
However, there is research being done on this holy grail of storage as georgia tech has made a feasible way in organizing dna strands for storage. They have achieved this by offering a one inch chip with several microwells, strands are grown in parallel inside these wells at some point.
These photonic chips will also include a second layer of electronic controls, made in your standard complementary metal oxide semiconductor that will initiate the chemical process of building. Each strand of dna one base at a time the challenge is to push the density of the dna as high as it can go and ultimately adding electrical control.
There's still a lot of questions on access time bandwidth and volatility of these photonic chips.

if we can solve the initial fabrication issues along with figuring out how to increase photonic processor speeds without causing decoherence in wavelengths?
but if we do figure out these problems this type of computing architecture will be a very strong framework for future machine learning and may even lead to something which can imitate the human mind.
