1.6T PASIC

OpenLight’s PASIC platform enables the design and manufacture of breakthrough, 1.6Tbps, fully integrated optical transmitter interconnect chips for next-generation, hyperscale datacenters.

Using OpenLight’s revolutionary, Heterogenous Integration, the Indium Phosphide (inP) based lasers, EAM and all other active components, are bonded onto the silicon as part of the integrated photonics chip. This breakthrough brings highly scalable benefits to the datacenter supply chain. This includes production efficiency, cost, reliability and capital equipment benefits to the accelerated demand for bandwidth.

OpenLight’s 1.6T platform also brings revolutionary advantages to AI, High Power Computing (HPC) and machine learning (ML) applications.

# OpenLight 1.6T PASIC technology platforms

The DR8 platform achieves 1.6T using 8x channels at 200G per channel.

The FR4 platform achieves 1.6T using 2x multiplexed fibers, each with CWDM channels at 200G per channel.

These platforms help to achieve efficiency levels better than 3 pJ/bit for datacenters, compared to today’s modules at greater than 5 pJ/bit. The platforms provides a path fo scale to 400G/ channel for 3.2T and beyond.

OpenLight’s open platform PDK (Process Design Kit) allows customers to design 1.6T PASICs (Photonic Application Specific Integrated Circuits), for their own, unique applications, or tap into OpenLight’s inhouse, design services. OpenLight’s PDK has a comprehensive library of standard photonic components for adding to the PASIC, including the following:

OpenLight’s PDK has a comprehensive library of standard photonic components for adding to the PASIC, including the following:

InP DFB lasers
InP Electro-Absorption Modulators (EAM)
InP Semiconductor Optical Amplifiers (SOA)
Metal Oxide Varistors (MOV) for power regulation
InP Photo Detectors
Silicon/Silicon Nitride Waveguides and passives components
Built-in monitors and temperature sensors

OpenLight provides individual components die, Starter kits and Evaluation kits to support customers with their own 1.6T PASIC design, development and testing.

# The OpenLight 1.6T value proposition

OpenLight’s Hetrogenous Integration allows multiple active components to be integrated on the same PASIC, silicon photonics chip. This removes the need to source, package and assemble separate, discrete components, and brings the following supply chain benefits:

OpenLight’s 1.6T PASIC chips deliver low optical loss with up to 90% coupling efficiency between lasers and waveguides. This efficiency significantly reduces power consumption and heat.

Although OpenLight’s 1.6T PASIC’s are produced using InP (Indium Phosphide), its higher cost when compared to silicon is counteracted by reduced power consumption; wafer channel density; the ability to scale; and the reduced demand for system cooling by air conditioning, heat sinks or fans.

OpenLight’s 1.6T PASIC chips include active components. Reliability and chip yield are increased as a result of less assembly steps, with less discrete parts to fit and align correctly. The chips are also hermetically sealed, reducing the failure risk from moisture in the field, which increases product life.

The production and assembly process time, or ‘touch time’, of OpenLight’s 1.6T PASIC chips is reduced, bringing efficiency and increased machine capacity to manufacturers. Initial figures show that semiconductor foundries using OpenLights 1.6T PASICs, with heterogenous integration, can expect a staggering 5x increase in capacity from the same machines. This allows manufacturers to scale easily and meet the ever-increasing demand for 1.6T, optical solutions.
