Slide 22 shows "Light Engines" as one of the product designs completed, this article give a better understanding of a light engine

Light engines are the next phase of development in the ever-shrinking optical interface.

Integrated Light engine

In recent years there has been significant focus on heterogeneous integration on the silicon photonics platform.

With the switch capacity increasing from the current generation 12.8TBit/s to 51.2TBit/s in the near future, there is a need for low power, optical interconnects to be co-packaged near the switch to minimize power consumption. These miniaturized optical interconnects will be silicon photonics based and have the drive electronics and lasers heterogeneously integrated on the same substrate. This heterogenous integration will allow the performance of the electronics to be optimized independent of the photonics and will be critical for the highly integrated data center interconnect modules. Here we present details of such a light engine consisting of a silicon photonics substrate with the optical components, 2.5D heterogeneously integrated with InP DFB lasers, and modulator driver and transimpedance amplifier (TIA) made using SiGe technology.
