they closed STC last year.
( "decided to transition to a 'fabless' radiation-hardened electronics business model, closing the Semiconductor Technology Center foundry and outsourcing its wafer fabrication." )
note, that's STC (in Manassas Virginia), not BAE ES (the microelectronics advanced technology group in New Hampshire which works with POET).
the ES foundry’s capabilities include monolithic microwave integrated circuits (MMICs) and other devices based on gallium arsenide and gallium nitride. BAE Systems has produced compound semiconductor MMICs and devices in its Nashua facility for more than 20 years for use in its electronic warfare, communications, radar, and weapon systems.
product-wise, that includes things like this.
trivia for today: of the 52 current job openings at BAE ES, three-quarters of them require Top Secret security clearance (or higher, including polygraph+SCI), and all of them require US citizenship. I wouldn't be surprised if some elements required DoE Q or L, either.
this sort of screening likely accounts for why there are rarely leaks about POET, and why news (or lack thereof) is the way it is.
