Giulia Pippione

Optimized solutions and manufacturable processes for high-power multiemitter laser

In this presentation the development of hybrid lasers is presented, from the early devices to the required technology for future devices.  Here we will focus on one of the most simple hybrid PIC devices consisting of only 2 material platforms: a Semiconductor optical amplifier (SOA) and a micro-ring based wavelength selective mirror in Silicon Nitride. The resulting device harvests best of both worlds, here:

1- The SOA gives a high optical output power, due to the high optical gain.


2- The Silicon Nitride PIC, giving the laser an ultranarrow linewidth thanks to the Low loss characteristics, and the unique characteristics explained.

The performance of typical devices is presented. And key developments in assembly techniques that will pave the way for future hybrid devices.

About the Speaker

Giulia Pippione received Master Degree in advanced technologies in Physics in 2016, in Turin. Since 2017 she is in Convergent Photonics Italia as responsible of the optical packaging of high power multiemitter laser diodes. She is now involved in the optimization of processes of micro-optics alignments for laser beams collimation, improvement of production processes and development of new packaging solutions for laser diodes.
