Customer Success Story

Customer Success Story

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.

Why people love Tidy3D

“Tidy3D's Incredible speed enables us to address long-standing problems and resolve the fundamental issue that have been debated for several decades”

Hui Cao
Professor of Physics,
Member, National Academy of Sciences

“Tidy3D can achieve simulation speeds of approximately two orders of magnitude on the premise of achieving the same simulation accuracy. This feature can potentially be the game changer for the photonics community”
