"Market has ‘legs’
The veteran CEO added that, so far, demand for VCSELs in immediate 3D sensing applications is dominated by a “very few” customers. “The number of [near-term] prospects and the number of projects that we're working on don't have a lot of demand yet, but where we’re supplying prototypes, samples, small volumes, for testing and for the building of systems, there are dozens and dozens of customers that are in that bag,” Rawls said.

“It's obviously a market that's growing; we think [it] is going to have legs. The real question is going to be what are the apps that people are going to write once they have this ability to do precision 3D sensing?”

While Finisar is not in the business of writing those apps, Rawls expects programmers to be “turned loose” in the near future as they look to exploit the new capabilities, with long-distance facial recognition one possibility.

“There's a lot of excitement generally in the people that are working in this field,” he told Finisar’s investor call. “And if any of their estimates in the future come through, there aren't enough VCSELs capacity in the world to take care of this.”
