Contactless All-Photonic Balanced Ternary Computing Device

Overview

A contactless variant of the foundational device in which all electrical contacts are removed. Three photonic inputs at distinct wavelengths carry every control function that the contacted device performs with metal electrodes, bonding pads, and alternating-current wiring rails.

Trit direction — the choice between +1 and −1 — is the function that previously required an electrical AC terminal. Here it is set by a piezoelectric shell surrounding the outer nanotube, driven optically. The device therefore has no electrical interface at all.

Removing contacts removes contact resistance, electromigration, and the alignment and bonding steps that dominate fabrication difficulty at nanotube scale. Shell material, crystallographic phase, thicknesses, and the three operating wavelengths are shared under mutual NDA.

Key Innovations

• Zero electrical contacts — all inputs are photonic
• Piezoelectric-shell trit direction control replacing the electrical AC terminal
• Eliminates metal electrodes, bonding pads, and wiring rails
• Removes contact resistance and electromigration as failure mechanisms
• Fully optical addressing, directly compatible with three-dimensional array integration

Why It Matters

The contacted device already uses photons for two of its three inputs. This patent closes the remaining gap by making direction control optical as well, which turns the device from a mostly-photonic element into an entirely photonic one.

That matters for integration: a device with no electrical interface can be placed anywhere light can reach, and does not need a wiring plane of its own.
