PHOTONIC COMPUTING APPARATUS

Disclosure Highlights & Public-Facing Summary

Inventor: Rusty William Atwood   |   Provisional Application No. 64/115,949   |   Filed July 21, 2026

What This Is

A hexagonally-stacked, photonic-superconducting computing architecture that moves data as light through braided superconducting conduits and stores it in three physically distinct memory mechanisms within a single unified structure. The design is disclosed in provisional patent application 64/115,949, filed with the USPTO on July 21, 2026, under the title “A Photonic Computing Apparatus and Methods for Manufacturing the Photonic Computing Apparatus.” This is Rusty Atwood's second patent-pending invention, following his solid-state nickel-magnesium battery design.

The Headline Numbers

• Up to 512 independently addressable optical channels per conduit — 8 orbital-angular-momentum (OAM) modes × 64 wavelength channels.

• Seven-stack hexagonal macro-architecture — six outer stacks plus one central stack, each roughly 500 layers tall.

• Three distinct memory mechanisms living side by side — rare-earth optical emission/storage, magneto-optical/magnonic (garnet) storage, and ferroelectric crossbar storage — repeating every ~10 layers.

• 10–20× linear shrink via a hydrogel “implosion” fabrication process — pattern it big, then shrink it down to nanoscale with everything still in place.

• No cryogenic cooling required — the superconducting graphene strands rely on intrinsic (magic-angle) superconductivity rather than external refrigeration.

Five Things Worth Leading With

1. Light that carries its own “twist” as an extra data dimension

Instead of just wavelength-division multiplexing, each conduit encodes data onto orbital angular momentum (OAM) — a helical twist in the light's phase front. Combined with 64 wavelength channels, this lets a single physical conduit carry hundreds of independent data streams at once, without adding more physical waveguides.

2. Superconducting light pipes that work without a fridge

Each conduit contains three braided strands built from three-layer, magic-angle-twisted rhombohedral graphene — a material that is intrinsically superconducting at its native transition temperature, avoiding the cryogenic cooling overhead that burdens most superconducting computing architectures. Strands are sheathed in boron nitride nanotubes for insulation and include a rubidium-based interface for optical amplification.

3. Three totally different memory types, one shared platform

• Rare-earth ring (dysprosium/terbium/europium/thulium-doped) — generates its own light (7 discrete emission lines, 450–800 nm) AND receives/stores externally delivered optical data using the same dopant sites.

• Garnet ring (strontium-doped yttrium iron garnet) — carries an optical channel and a magnon (spin-wave) channel simultaneously in the same crystal, with cerium doping for one-way (nonreciprocal) light transmission.

• Ferroelectric crossbar (lanthanum-doped aluminum scandium nitride) — dense, non-volatile storage at intersecting conductive elements, built on AlScN ferroelectric work already demonstrated at kilobyte scale with >95% device yield.

4. A graded-composition bridge instead of an abrupt junction

Where a photonic conduit meets a memory ring, an approximately 5 mm lanthanum-scandium taper gradually shifts refractive index from a conduit-matched value to a memory-matched value, cutting reflection loss and mode mismatch while mechanically anchoring the two parts together — addressing a chronic weak point in photonic packaging.

5. Building nanoscale 3D structures by patterning big, then shrinking

The whole assembly is fabricated using an implosion hydrogel process: a swollen hydrogel scaffold is patterned in 3D at an enlarged, easy-to-work-with scale using two-photon lithography, functionalized with the target materials (superconducting, rare-earth, garnet, ferroelectric, shielding), then isotropically shrunk 10–20× per dimension via controlled ionic exchange and dehydration — landing every component at nanoscale resolution while preserving their relative 3D arrangement.

The Problem It's Aimed At

Conventional photonic and quantum computing architectures are bottlenecked by a small number of wavelength channels, suffer crosstalk as waveguides are packed tighter, rely on a single memory mechanism (forcing tradeoffs between speed, density, and non-volatility), and often require expensive cryogenic cooling for any superconducting elements. This design proposes addressing all four simultaneously within one modular, repeatable architecture.

Framing Notes for Outreach

• This is a provisional patent application — not yet examined or granted. The specification itself repeatedly frames the work as proposed embodiments whose dimensions, materials, and performance would be confirmed through simulation, fabrication, and empirical testing.

• Individual sub-components (AlScN ferroelectric crossbars, Ce:YIG magneto-optic rings, magic-angle twisted graphene, OAM+wavelength multiplexing, implosion fabrication) each have real prior published research behind them — the novelty claimed here is combining them into one unified, repeatable, cryogen-free architecture.

• Good hook for a technical audience: “What if a single photonic computing platform could multiplex light by both color and twist, store data three different physical ways in the same structure, and be built by shrinking a 3D-printed hydrogel scaffold down to the nanoscale?”

• Sequencing reminder: battery disclosure goes out first; this photonic disclosure follows once that rollout is complete.
