Snochip

SNOChip, Inc. is a Princeton, New Jersey optics and photonics company that designs and manufactures on-chip nano-optical components. It builds microlens arrays, computer-generated holograms, and optical metasurfaces (metalenses) that are fabricated with semiconductor IC processes rather than traditional grinding, polishing, and molding, so they can be integrated directly with semiconductor lasers and sensor chips. The company's initial commercial focus is infrared thermal imaging and sensing optics for defense and aerospace customers, and it supports the range from proof-of-concept prototypes through large-scale production. Founded in 2022, it has been funded by New Jersey CSIT Catalyst R&D, SBIR awards, and the Luminate NY accelerator.

Manufactures flat optics using standard semiconductor chip fabrication instead of conventional lens grinding and molding, which makes the optics thin enough to integrate directly onto laser and sensor dies and enables functions conventional lenses cannot deliver, such as achromatic metalenses and broadband dispersion engineering.
