This is interesting. Never heard them talk about underwater communications.!!

ME commons is the main focus of the market but also mispricing the potential here of quantum computing and AI.

Visible GaN DFB lasers are a compact, single-frequency laser light source that meet the unique requirements of
next-generation technology, such as quantum sensing and navigation, advanced robotics, underwater and space
communications, and bio-medical applications. While DFBs are commonly used in non-visible wavelengths, they
are not commercially available in the near ultra-violet (UV) and visible spectrums.

“Our recent breakthroughs in GaN-based DFB lasers offer a game-changing solution for emerging quantum
sensing, navigation, and communication needs, as well as critical next-generation defence and aviation
applications. Visible DFB lasers offer multiple advantages for these emerging technologies, providing precise stable
wavelengths and high-power narrow spectral width. They also address a key challenge for quantum computing,
which currently utilise large laser systems with significant power and space requirements. Thousands of GaN DFB
lasers are processed simultaneously on one two-inch wafer, potentially paving a way for quantum computers to
scale-up in volume production as well as scale-down in size,” said CEO Jim Haden.
