Dan Sadot

Dan Sadot (} (born 1962) is an Israeli optical communications scientist and entrepreneur.

He is a professor of electrical and computer engineering at Ben-Gurion University of the Negev, where he holds the Reuben and Frances Feinberg Chair in Electro-Optics.

Sadot is also the founder of several start‑ups in the field of optical communications.

He earned B.Sc., M.Sc., and Ph.D. degrees in electrical and computer engineering from Ben‑Gurion University. Sadot won the Clore doctoral scholarship and completed his doctorate summa cum laude in 1994 on electro-optical remote sensing under the supervision of Natan Kopeika.

Academic career Sadot was a Fulbright and Rothschild postdoctoral fellow in optical communications at Stanford University, supervised by Prof. L. G. Kazovsky. He joined the Electrical and Computer Engineering (ECE) Department at Ben‑Gurion University as a senior lecturer in 1995, becoming an associate professor in 2001 and a full professor in 2009.

Research Sadot’s research focuses on optical communication and networking.

His studies include signal processing in optical communications, coherent detection, optical OFDM, atmospheric optics, dynamic WDM networks, and security in optical communication networks.

Industry and entrepreneurship Sadot has founded several start‑ups, including TeraCross (1999–2002), Xlight Photonics (2000–2003), MultiPhy (2006–2018), and Banias Labs (2020–2022), which was acquired for $240 million by Alphawave.

In 2022, Sadot founded CyberRidge, a company that protects data traveling over fiber‑optic networks by encrypting it at the photonic (light) layer. He also serves as its CEO.
