ist noch nicht gut bei vcsel and micro LED und mini LED
cc. They're both gallium nitride as well as arsenic phosphide opportunities. And so the tool that we're developing for the photonics market is really an arsenic phosphide tool to compete in that $100 million market we don't have a strong position today. So that would include VCSELs; edge-emitting lasers; red, orange, yellow specialty LEDs and the like; as well as microLED. And then really the GaN opportunity for us would be in power electronics -- GaN-on-Silicon power electronics. And down the road, opportunities in RF for kind of greater than 20 gigahertz millimeter wave type RFID applications. It will be for GaN.

Got it. And I've recently heard some other folks talking about microLED, at least some development going on. Is that still a ways away before being revenue opportunity for you all?
William Miller
Yes. We are engaged with many of the players in the display space, and they are working through technical challenges. Some of those technical challenges are driving new performance requirement in our MOCVD epitaxial growth, which is good for us. But there are also system-level integration challenges like transferring the LEDs, et cetera. And so, I think, you're going to see some first adoption of say mini LEDs, kind of, larger size LEDs. But true microLED displays, I think, are a few years out still, but there's still a fair amount of activity ongoing in that area.
