A New Era of Connectivity

Ayar Labs optical I/O chiplets integrate into traditional semiconductor packages.

The Difference

Our products move data from chip to chip using light instead of electricity transmitted through copper wires.

The Result

Breaking through the performance, power, and distance limitations of copper interconnect.

The Impact

New system architectures that push the boundaries for AI, cloud, high-performance computing, 5G, and LIDAR.

TeraPHY™: A High-density Electronic-Photonic Chiplet

TeraPHY™ is a Monolithic In-Package Optical I/O (MIPO I/O) solution that:


Uses industry standard cost-effective silicon processing techniques to develop high speed, high density, low power optical based interconnect “chiplets”.

  • When combined with our multi-wavelength laser, they replace traditional electrical based chip-to-chip I/O.
  • They are “smart” chiplets that contain both electronic and photonic elements that offer easier integration without complex SerDes I/O functions.

Can drive tens of Tb/s of bandwidth at <5 pJ/b up to 2km – directly out of an ASIC/CPU/FPGA package.


Modular multiport design with each port carrying 8 channels of light. Each port carries the equivalent bandwidth of a x8 PCIe gen5 link.


Has a wide,high bandwidth AIB electrical interface to connect to partner silicon.

  • The digital AIB interface is easily incorporated in partner silicon enabling easy bandwidth scaling without complex SerDes integration cycles

SuperNova Light Supply

SuperNova is a multiwavelength, multi-port light source that:


Supplies the continuous wave (CW) light that powers TeraPHY.


Is a photonic integrated circuit (PIC) that generates eight or sixteen wavelengths of O-band light, multiplexes them, splits the power, and amplifies it to eight or sixteen output ports.


Is capable of supplying light for 256 channels of data, or 8.192 Tbps.

"Photonics has really become the next step in the roadmap. I think we’re finally at a point now where this is starting to become, realistically speaking, one of the only options left. [Ayar Labs] is really – one of – if not the only place that has really been able to take this production-level CMOS process technologies and to implement integrated photonics out of it."

– Elad Alon, Co-director of Berkeley Wireless Research Center, Professor of Electrical Engineering and Computer Science at UC Berkeley
