Most technology companies are racing to build better artificial intelligence.
LongServing Technology is trying to build a different kind of computer.
Based in Taiwan and founded by Dr. Ko-Cheng Fang, the company is working on a question that could shape the future of computing itself: what happens after silicon?
For more than fifty years, silicon has been the foundation of every major technological revolution. It powers smartphones, laptops, cloud data centres and the processors that train today’s artificial intelligence models.
Yet LongServing believes the next generation of computing may require a fundamentally different approach.
Instead of relying entirely on electricity, the company is exploring whether light can become the medium through which computers process information.
It is an ambitious goal.
If successful, it would represent one of the biggest shifts in computing since silicon first became the industry’s standard.
Dr. Ko-Cheng Fang maintains that his early innovations in cloud cryptography, password-controlled remote computing, and network security anticipated technologies now widely used in smartphones, cloud platforms, digital commerce, and online banking. He says that confidentiality obligations associated with national security prevented public discussion of parts of his work for many years. Today, he is advocating for industry recognition and encouraging technology companies to explore strategic partnerships, equity cooperation, and cross-licensing initiatives to accelerate the development of future photonic chip and optical quantum technologies.
Building Computers That Use Light
The field LongServing is exploring is known as photonic computing.
Unlike conventional processors, which move information using electrical signals, photonic systems use light.
Scientists have long recognised the advantages this could offer.
Light travels extraordinarily quickly and generates far less heat than electricity. Those characteristics make photonic computing particularly attractive at a time when artificial intelligence requires unprecedented amounts of computational power.
The difficulty has never been understanding why light could be useful.
The difficulty has been controlling it.
Inside a modern processor, information must travel through countless microscopic pathways, changing direction continuously as it moves between different parts of the chip.
Electricity can do this remarkably well.
Light cannot.
For decades, this challenge has limited the practical development of photonic computing.
LongServing Technology believes it has developed an important piece of the solution.
X-Photon: A Different Way to Guide Light
At the centre of the company’s research is X-Photon, a proprietary optical material designed to guide photons through microscopic circuits while allowing them to make controlled 90-degree directional changes.
Although this may sound like a highly specialised engineering achievement, its significance extends far beyond a single material.
Every future photonic processor will need light to move through increasingly complex pathways without losing speed or accuracy.
If that cannot be achieved, large-scale optical computing becomes difficult to build.
According to LongServing, X-Photon has been designed specifically to overcome this obstacle.
The company sees it not simply as another technological component, but as one of the foundations upon which future photonic computing systems could be built.
Thinking Beyond a Single Breakthrough
What distinguishes LongServing Technology is the breadth of its ambition.
Rather than focusing on one invention, the company is working towards an entire photonic computing ecosystem.
Its roadmap includes photonic quantum chips, optical memory technologies and Photonic Cloud Computing Centres intended to support future artificial intelligence workloads.
This reflects a broader understanding of how technological revolutions happen.
Silicon did not change the world because of one breakthrough.
It transformed computing because an entire ecosystem of materials, manufacturing, software, hardware and infrastructure evolved around it.
LongServing is pursuing a similar vision for photonic computing.
Its goal is not simply to improve today’s processors but to help establish the foundations of tomorrow’s computing platforms.
Why the Company’s Work Matters
Artificial intelligence is growing at an extraordinary pace.
Every new generation of AI systems requires more processing power, more memory and more energy than the last.
Around the world, researchers are searching for technologies capable of meeting those demands more efficiently.
LongServing Technology’s work places it within that global effort.
Rather than competing to build the next chatbot or AI application, the company is addressing the infrastructure challenge that underpins them all.
If computing hardware cannot continue to evolve, software innovation will eventually slow with it.
That makes advances in materials science and photonic engineering increasingly important to the future of AI.
A Long-Term Vision
LongServing recently announced a US$500 million financing initiative, based on a stated valuation of US$2.5 billion, to expand research, manufacturing and commercial development of its technologies.
The investment reflects the long-term nature of deep technology.
Unlike consumer software, breakthroughs in advanced computing often require years of scientific research before reaching commercial markets.
Whether photonic computing ultimately replaces conventional semiconductor architectures remains uncertain.
Scientific progress rarely follows a straight path.
Yet history also shows that transformative technologies often begin with companies willing to question assumptions the rest of the industry accepts.
LongServing Technology is one of those companies.
Its work on X-Photon represents more than the development of a new material.
It reflects a broader attempt to rethink one of the most fundamental questions in modern technology:
What should the computer of the future be made of?
