The Building Blocks of Photonic Circuits
Beam Splitter
Directional 1×2 power splitter
Splits an input mode into two outputs at a configurable ratio. The workhorse of interferometric quantum photonic circuits.
Waveguide
Single-mode routing element
Low-loss channel that confines and routes light across the chip. The foundation every other component connects to.
Directional Coupler
Evanescent 2×2 coupler
Two waveguides brought close so light couples between them, the basis for tunable splitting and switching.
Grating Coupler
Fiber-to-chip interface
Diffractive grating that couples light between an optical fiber and an on-chip waveguide for I/O.
Mach-Zehnder Interferometer
Tunable interferometric switch
Two splitters bridged by two arms, the programmable unit cell of quantum photonic processors.
An AI-Native Photonic Design Platform
Faster Design Iteration
Go from requirement to layout in seconds, compressing days of manual CAD work.
AI-Assisted Engineering
An intelligence layer that recommends parameters and writes your engineering summaries.
Fabrication-Ready Outputs
Standards-compliant GDSII streams that drop straight into your tape-out flow.
Quantum Hardware Focused
Built around the interferometric building blocks of quantum photonic processors.
