Memory,
refracted.
Prism stores data as a standing interference pattern of laser light, locked inside a photonic crystal lattice. No electrons to refresh, no capacitors to leak — just light, held still.
Three steps from photon to bit.
Prism replaces the capacitor-and-transistor cell with a waveguide etched directly into a photonic crystal substrate. Data is written, held, and read entirely in light.
Encode
A laser diode array modulates incoming bits into a coherent photon pulse pattern, routed through waveguides etched into the lattice substrate.
Lock
The pulse interferes within the photonic crystal lattice, freezing the standing-wave pattern as a stable, non-volatile state — no power required to hold it.
Read
A low-power probe beam samples the interference pattern via phase-sensitive detection, returning data at picosecond resolution without disturbing the stored state.
Bandwidth, next to what you know.
Measured per-module sequential bandwidth. Log scale — each gridline is a 10× step.
Three form factors, one lattice.
All modules share the same photonic die and JEDEC-adjacent pinout — pick the capacity and interconnect for your platform.
