DsynQ Research Preview

This platform is currently a beta version and intended for research and evaluation purposes. Generated designs, simulations, and AI analysis are provided as engineering aids and should be validated before fabrication.

How it works

From requirement to tape-out in four steps

Step 01

Define Requirements

Describe your device in plain language or structured fields - wavelength, platform, objective.

Step 02

AI Design Assistant

The AI engine translates intent into a validated, structured photonic design specification.

Step 03

Photonic Layout Generation

gdsfactory synthesizes real chip geometry with an interactive SVG preview.

Step 04

Export Manufacturing Files

Download fabrication-ready GDSII, SVG, JSON, and an engineering report.

Supported components

The building blocks of photonic circuits

Beam Splitter

Available

Directional 1×2 power splitter

Splits an input mode into two outputs at a configurable ratio. The workhorse of interferometric quantum photonic circuits.

Waveguide

Available

Single-mode routing element

Low-loss channel that confines and routes light across the chip. The foundation every other component connects to.

Directional Coupler

Available

Evanescent 2×2 coupler

Two waveguides brought close so light couples between them - the basis for tunable splitting and switching.

Grating Coupler

Available

Fiber-to-chip interface

Diffractive grating that couples light between an optical fiber and an on-chip waveguide for I/O.

Mach-Zehnder Interferometer

Available

Tunable interferometric switch

Two splitters bridged by two arms - the programmable unit cell of quantum photonic processors.

Example AI Design Review

Grounded, structured - quotes only figures from the design

“Candidate A meets the balanced-split objective at 96.4% efficiency with 0.18 dB insertion loss across a 42 nm band. The design is robust to typical fabrication tolerances (fab score 88/100).”

Risks

  • Coupler gap sensitive to +/-10 nm lithography drift
  • Bandwidth narrows at the band edges

Next steps

  • Sweep coupler length for tolerance margin
  • Confirm with a full-wave simulation before tape-out
