POET Technologies Introduces “POET Starlight” for the Artificial Intelligence Market and Receives Advanced Purchase Order from Celestial AI

Toronto, Ontario, April 25, 2023 -- POET Technologies Inc. (“POET” or the “Company”) (TSX Venture: PTK;
NASDAQ: POET), the designer and developer of the POET Optical Interposer™ and Photonic Integrated Circuits
(PICs) for the data center, telecommunication and artificial intelligence markets, today announced “POET
Starlight™”, a packaged light source solution for AI applications. POET has 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 chips and its technology roadmap are complementary to our advanced silicon photonics and
system-in-package technologies,” said Preet Virk, Co-founder and COO of Celestial AI. “We are pleased to
continue our collaboration with POET Technologies, building on its optical interposer technology to enable us to
meet our performance, scale, and cost targets.”

The POET Starlight products are packaged light engines based on POET's LightBar™ platform, which recently
earned industry praise when it was demonstrated at OFC. Chip developers are working to redesign the core of
computer architecture to incorporate light for communication among chips or to perform complex computations,
all in an effort 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. POET achieves its low-cost solution
through the use of features and benefits of the POET Optical Interposer platform and the “semiconductorization”
of photonics fabrication processes.

“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.”

POET’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.

A recorded interview with POET’s Senior Vice President – Product Line Management, Raju Kankipati, called "POET
Starlight Announced as Part of AI Hardware Partnership", can be found on the Company’s YouTube channel using

About POET Technologies Inc.
POET Technologies is a design and development company offering integration solutions based on the POET
Optical Interposer™, a novel platform that allows the seamless integration of electronic and photonic devices into
a single multi-chip module using advanced wafer-level semiconductor manufacturing techniques and packaging
methods. POET’s Optical Interposer eliminates costly components and labor-intensive assembly, alignment, burn-
in and testing methods employed in conventional photonics. The cost-efficient integration scheme and scalability
of the POET Optical Interposer brings value to any device or system that integrates electronics and photonics,
including some of the highest growth areas of computing, such as Artificial Intelligence (AI), the Internet of Things
(IoT), autonomous vehicles and high-speed networking for cloud service providers and data centers. POET is
headquartered in Toronto, with operations in Allentown, PA, Shenzhen, China and Singapore. More information
