Our Goal
Optalysys is building the hardware that will enable fully homomorphic encryption at scale.
Data security creates a paradox.
The most valuable data is the data that can’t be shared.
Fully homomorphic encryption solves this problem by allowing truly blind computation.
However, this requires a massive shift in computing power.
The Solution
Go beyond the limits of electronics with optics.
Fully homomorphic encryption belongs to a class of problems that cannot be solved efficiently using standard Von Neumann architectures.
We combine optical device physics with bespoke supporting electronics to create the ultimate FHE accelerator.

Features
Combined digital-photonic infrastructure on a single die. Optical modulators and detectors convert information to and from the processing environment.
Designed for digital integration. High performance chip interfaces allows Etile to work with existing multi-chip-module technology.
Highly scalable. Multiple photonic processing stages can fit on a single die. Calculations can be scaled over multiple Etiles.
Lower power consumption and thermal emission than electronic equivalents.
Massively flexible. The output of the photonic calculation can be used to construct transforms of different sizes.
Standard PCIe interface for easy integration with supporting hardware.
The Science
At the heart of Etile is a photonic circuit
We control light in silicon photonic waveguides using existing modulation technology.
We can convert complex-valued digital data directly into an optical representation.
Collectively emitting these encoded beams into a free-space environment results in a near-instantaneous transformation of the data through optical interferences.
This calculation is near-instantaneous, consumes no power, and generates negligible heat.
Many of these free-space processing stages can be constructed on a single die.
The optical signals containing the transformed data are then converted back into digital form. This digital data can then be recombined into transform operations of greater size and precision.

Advantages
Ultra-high speed operation provided by the optical transform.
Etile is designed using standard high-speed silicon photonic technologies and foundry PDKs, ensuring consistent and exceptional performance.
All the relevant intellectual property is owned by Optalysys.
Etile is a modular stand-alone technology – the fastest and most efficient transform processor.
The device physics of Etile perform an inherently complex-valued operation. The free-space transform stage can be thought of as being to FHE what the transistor is for conventional electronics.
Optalysys Enable
Optalysys Enable leverages the power of Etile to provide the massive vector transforms needed for fast and efficient FHE.
In the Enable system, Etile is paired with custom architecture and logic designed around the unique needs of FHE. A dedicated FHE-focused instruction set allows ready low-level interfacing with FHE libraries.
Rounding out the platform is high-density chip-to-chip communication, solving the problem of data transfer that impedes conventional rack-scale FHE solutions.
The result is a single MCM accelerator unit that vastly outperforms a HPC cluster with respect to FHE compute.
