POET Technologies introduces Starlight for AI

Technologies and Products

POET Technologies Inc. has launched POET Starlight TM, a packaged light source solution for AI applications. POET has also entered into an agreement with Celestial AI, creators of the Photonic Fabric TM, for development and production of POET Starlight packaged light sources and has received an advanced purchase order for initial production units.

POET’s Starlight products are packaged light engines based on its LightBar™ platform.  Chip developers are working to redesign the core of computer architecture to incorporate light for communication among chips or to perform complex computations, to eliminate the bandwidth and power-efficiency bottlenecks inherent in electronic devices.  Each such chip requires one or more light sources able to provide several frequencies of light integrated into the fabric of the device. POET’s Starlight products integrate active components like lasers and certain other passive optical and electrical components into the Optical Interposer to provide a complete light source solution that can be integrated on a host board and connected to chips and ASICs with built-in silicon photonics.

The company says it achieves its low-cost solution through the use of features and benefits of the POET Optical Interposer platform and the “semiconductorisation” of photonics fabrication processes. ’s Starlight C-Band and O-Band LightBar products incorporate monolithically integrated passive components like multiplexers, demultiplexers, splitters, combiners, and waveguides. Known-good high power CW lasers and monitor photodiodes are flip chipped and passively attached to the optical interposer platform. POET expects to complete design verification testing and reliability qualification of the Starlight engines by the end of 2023 and start production in the second half of 2024. The size of the AI chip market is projected by Allied Market Research to reach $263 billion by 2031.

“External light sources for Artificial Intelligence applications has been one of the key verticals for POET Technologies. We are delighted to continue to work with Celestial AI to provide a high-volume manufacturable solution for their optical interconnect technology platform,” said Dr. Suresh Venkatesan, Chairman and CEO of POET Technologies.  “The ability for POET to passively attach high power CW lasers on its optical interposer at wafer scale enables the use of single known-good laser chips and eliminates the need for laser arrays which can be cost prohibitive for high-volume applications. The POET team has worked closely with Celestial AI to define a low-cost packaging solution that is up to 75% lower in cost than competing solutions and is highly scalable for the volumes that Celestial AI is projecting.”
