Every technological age is defined by the material that quietly underpins it. Stone shaped the first civilisations. Steel transformed industry and architecture. Silicon became the foundation of the digital economy, enabling everything from personal computers and smartphones to cloud infrastructure and, more recently, artificial intelligence.
Yet no material remains dominant indefinitely.
As AI models become larger, more sophisticated and increasingly computationally demanding, the silicon architectures that have powered modern computing are approaching a period of diminishing returns. The challenge is no longer simply designing faster processors. It is finding ways to deliver greater computational performance without proportionally increasing power consumption, heat generation and manufacturing complexity.
The next leap may therefore depend less on refining silicon than on rethinking the medium through which computation itself takes place.
That is the proposition being explored by LongServing Technology, the Taiwan-based company founded by Dr Ko-Cheng Fang. Rather than relying exclusively on electrons travelling through ever-smaller transistors, the company is developing computing architectures that use photons—particles of light—as the carriers of information.
Following its recent introduction of a photonic quantum chip architecture, LongServing Technology has announced another milestone: the validation of what it describes as X-Photon, a proprietary optical material designed to guide light through nanoscale circuits while enabling precise 90-degree directional changes within integrated photonic structures.
The company believes the material represents a significant step towards practical photonic quantum computing.
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.
When Silicon Begins to Slow
For decades, advances in computing have been driven by shrinking transistors. As components became smaller, processors became faster, cheaper and more energy efficient.
That trend is now becoming increasingly difficult to sustain.
As semiconductor manufacturing approaches dimensions below two nanometres, engineers face mounting challenges involving heat dissipation, electrical interference, fabrication complexity and energy efficiency. These constraints have prompted researchers across academia and industry to investigate alternative computing architectures capable of extending computational performance beyond the practical limits of conventional electronics.
Photonic computing has emerged as one of the more promising candidates.
Instead of transmitting information through electrical current, photonic systems rely upon light. Photons travel considerably faster than electrons while generating substantially less heat, making optical computing an attractive proposition for workloads such as artificial intelligence, where speed and energy efficiency have become equally important.
The principle has long been understood.
Turning it into practical hardware has proved considerably more difficult.
Teaching Light to Turn
Moving information with light is only part of the challenge.
Perhaps the greater engineering problem lies in controlling it.
Unlike electrical current, which can be directed through conductive pathways with relative ease, light naturally prefers to travel in straight lines. Guiding photons through microscopic circuits—and persuading them to change direction without significant signal loss—has remained one of the defining obstacles in integrated photonics.
LongServing Technology says X-Photon has been developed specifically to address this limitation.
According to the company, the material incorporates an optical channel capable of guiding photons while allowing controlled 90-degree reflections within the structure itself.
Dr Fang compares the mechanism to the behaviour of a conventional mirror. Light first passes through a transparent surface before reaching a reflective layer beneath it. X-Photon, the company says, applies a similar principle inside an integrated photonic material, where an embedded light-blocking layer redirects photons without forcing them to leave the optical pathway.
If scalable, such an approach could provide one of the essential building blocks required for increasingly complex photonic circuits.
Building at the Nanoscale
LongServing Technology also attributes much of X-Photon’s potential to the dimensions at which it operates.
The company states that the material functions with an optical wavelength averaging between two and three nanometres, enabling the construction of optical pathways suitable for advanced photonic processors and memory systems.
It further claims to have successfully fabricated optical circuits at the 10-nanometre scale—an achievement it considers another step towards highly integrated photonic computing platforms.
For Dr Fang, shrinking optical circuitry to these dimensions is not merely an engineering accomplishment but a prerequisite if photonic computing is to become commercially viable as an alternative to silicon-based processors.
Rethinking Computing Infrastructure
The company’s ambitions extend beyond a single material.
Its longer-term roadmap includes two-nanometre multi-bit photonic quantum chips, photonic memory technologies and large-scale Photonic Cloud Computing Centres designed to support future artificial intelligence workloads.
The premise is straightforward.
As AI systems continue to expand in scale, conventional semiconductor infrastructure may struggle to satisfy growing demands for computational throughput without corresponding increases in power consumption.
Photonic architectures offer a different approach.
Because photons generate significantly less heat while travelling at substantially higher speeds than electrons, optical systems could, in principle, deliver greater computational performance with markedly improved energy efficiency.
LongServing Technology has outlined an ambition to develop photonic computing platforms capable of achieving computational performance up to 1,000 times greater than conventional electronic systems while reducing energy consumption by as much as 90 per cent. The company notes that these remain long-term commercial objectives rather than current capabilities.
Financing an Emerging Ecosystem
Developing new computing architectures requires more than laboratory research.
Commercialisation demands manufacturing capacity, infrastructure and long-term investment.
LongServing Technology recently announced a strategic financing initiative valued at US$500 million, based on a stated company valuation of US$2.5 billion.
According to the company, the funding will support expanded photonic fabrication, optical cloud infrastructure and the continued commercial development of its technologies.
Dr Fang has also introduced what the company describes as a Strategic Equity Hedging Protocol, intended to establish a framework for future partnerships with global technology firms as the photonic computing ecosystem develops.
Beyond Silicon
Whether photonic computing ultimately succeeds silicon as the dominant computing platform remains an open question.
Substantial scientific, manufacturing and commercial hurdles remain before optical computing can be deployed at scale.
Yet the direction of travel is becoming increasingly clear.
Across research institutions and technology companies alike, attention is gradually shifting towards architectures capable of overcoming the physical limitations confronting conventional semiconductors.
LongServing Technology’s work on X-Photon, alongside its broader photonic quantum computing programme, reflects that wider movement.
If the next era of artificial intelligence is defined by a different material, it may not simply represent another technological upgrade. It could mark a more fundamental shift in how computation itself is conceived—from electrons moving through silicon to light travelling through carefully engineered optical pathways.
The history of computing has largely been written in silicon.
The next chapter, perhaps, will be written in light.
