SHERMAN, TEXAS — Apple has made its second notable investment this week, the latest into the facial recognition technology company, Finisar (FNSR.O).

The US$390-million investment announced Wednesday comes from Apple's US$1 billion Advanced Manufacturing Fund, created to finance the work of domestic manufacturers and create jobs in the U.S.

Apple (AAPL.O) announced the creation of the fund in May and plowed US$200 million into Corning Inc. (GLW.N), the maker of the Gorilla Glass that is used in Apple's touchscreens.

The Finisar investment will help the company boost production of vertical-cavity surface-emitting lasers, which Apple uses for Face ID, Animoji and Portrait mode selfies with the iPhone X TrueDepth camera and the proximity-sensing capabilities of AirPods.

Finisar will open a manufacturing plant in Sherman, Texas, about an hour north of Dallas, creating more than 500 jobs. Finisar runs a plant in Allen, just outside of Dallas.

On Monday, Apple revealed that it had acquired Shazam. That company makes the song-recognition app that Apple's digital assistant Siri has already been using to help people identify the music playing on their iPhones.

The investment announced Wednesday is a huge lifeline for Finisar. The company's stock had tumbled nearly 40 per cent this year after putting up disappointing numbers in its past two quarters.

Shares of Finisar Corp. leapt almost 30 per cent at the opening bell.
