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.
