Tidy3D includes a diverse set of advanced features for electromagnetic simulations implemented using the latest innovations in numerical algorithms.
Tidy3D leverages automatic differentiation to perform adjoint optimization of photonic devices. With two simulations per iteration, one can quickly and easily evolve a device towards optimal performance using inverse design.
Photonic integrated circuits (PICs) can span a huge area on chip, making them hard to simulate without breaking into individual components. With Tidy3D, we are able to reliably handle entire PICs in minutes. As an example, we demonstrate the simulation of an entire 8-channel de-multiplexer based on asymmetric directional couplers.Large PIC example
We recently simulated a large scale metalens. The device had a diameter of 100 wavelengths and required 2.7B grid cells.
This problem was too large to solve with convenential FDTD solvers, even using distributed computing. With Tidy3D, we simulated the whole device in less than 300 seconds.
Tidy3D allows Ayar Labs to substantially shorten the design cycle of photonic circuits. Excellent agreement between simulation and actual device performance gives the R&D team the confidence to iterate their design entirely on the computer, which substantially improves product performance and reduces the time to market.
“It’s amazing how fast the Flexcompute numerical solver runs,” Prof. Hui Cao said. “Some simulations that we expect would take days to do, it can do in just 30 minutes. This allows us to simulate many different random configurations, different system sizes, and different structural parameters to see whether we can get three-dimensional localization of light.”
Lumotive is a technology startup based in Redmond, Washington. It is a leading developer of optical semiconductors which are changing the rules for LiDAR across a wide range of 3D sensing applications. Their proprietary Light Control Metasurface (LCM™) solid-state beam steering chips are manufactured.
Leading a project to optimize photonic device design, Dr. Sean Sullivan, CTO at memQ Inc., was hampered by slow photonic simulation solutions, which slowed the chip design, fabrication, and testing cycle time. As a startup developing new quantum photonic hardware for long-distance distributed quantum information.
“Tidy3D is a user-friendly tool which speeds up our simulation process by orders of magnitude compared to a typical local computer. In addition, its support team is highly responsive and helpful.”
I really appreciate your (and your colleague’s) responsiveness helping out customers! It really makes a difference using your code and being able to run high-quality simulations.
