The Breakthrough
Longserving Technology has demonstrated a working optical channel test for its proprietary X-Photonmaterial, a transparent medium roughly 2–3 nanometers in wavelength that guides laser light the copper wire guides electrons, but without electrical resistance. On a 1×1 cm ceramic-substrate chip,laser light entering from the base travels through the channel and turns 90 degrees before reaching the surface, visibly proving light can be routed and controlled inside a solid material.
Because light moves at least 1,000 times faster than electrons, the company says X-Photon material can replace copper wiring on PCBs at far higher speeds while cutting power draw and heat. The material has already been used to fabricate 10-nanometer optical circuits and is positioned as the foundation for photonic CPUs and photonic memory.
How it works: X-Photon acts like glass, transparent to light, while a reflective layer at the back of the channel functions like the backing of a mirror, bouncing light along the path. No other known transparent material operates at a 2nm wavelength, which the company says makes the material unique.
A related sample, a 7-channel, 405nm violet micro-laser photonic coupling module measuring 1.2×0.8cm, demonstrates a 2-bit full-adder circuit with integrated memory, pairing the pendingphotonic-memory patent with active computing.
Photonic CPU Architecture
The proposed 3D Photonic CPU integrates photonic main memory (PRAM) and photonic flashmemory (PFlash) around a photonic logic-gate compute core. An optical waveguide interconnectlayer moves data at high speed with low power draw and immunity to electromagnetic interference,while a photonic register array and optoelectronic I/O interface round out the system. The wholepackage is built as a 3D Photonic System-on-Chip, unifying computing, memory, and communicationin one platform, a design the company positions for future AI and quantum-inspired computing.
Photonic Quantum Smartphone Concept
Longserving’s concept phone pairs a photo-electronic hybrid processor with a solid-state battery and a light-harvesting back panel for ambient-light charging. The front carries a Micro-LED eye-care display with adaptive brightness and zero flicker; the fiber-optic textured back cover hides sensors for gesture and eye-tracking control plus optical fingerprint authentication. An integrated LiFi visible-light communication array is pitched for gigabit-class wireless transfer that’s harder to intercept thanradio-based signals, with an internal system managing photonic, data, and power pathways to switch between high-performance and low-power modes.
X-Photonic AI GPU
The second-generation GPU architecture aims to remove optoelectronic conversion almost entirely,keeping electronic circuitry only at the external I/O interface. X-Photon material absorbs light and generates further photons through stimulated emission, handling data transmission, logic, and memory in one medium. A photonic capacitive memory layer stores both temporary and permanent state; a matrix compute tile array accelerates matrix multiplication, attention, and convolution operations; and an interconnect layer handles routing, scheduling, and error correction.
Claimed performance: 1,000× – 10,000× gains over conventional electronic GPUs under idealengineering conditions (up to 100,000× as a theoretical ceiling), 10× – 100× higher memorybandwidth, and over 90% lower power consumption.
X-Photonic Glass Photon Disc
On the storage side, Longserving is pairing the same glass substrate used in conventional discs with an X-Photon layer instead of copper wiring. The company cites up to 20 Gbps transfer speeds, 20TB+ capacity, and a 50-plus-year lifespan, versus roughly 2–6 Gbps, 1–2 TB, and a 5–10 year life span for copper-based glass discs, crediting the gains to zero electrical resistance in the photonic layer.
