Photonics researchers are developing semiconductor chips for miniaturised optical systems

At Tampere University, photonics researchers are developing semiconductor light emission chips for light-based sensing, LIDAR, and health monitoring. The research aims to find efficient means to integrate semiconductor chips in low-cost, low-dissipation power, and compact optical circuits using a silicon platform. A specific application target is monitoring harmful greenhouse gas emissions in the atmosphere.

In December 2022, Nouman Zia received his PhD with a thesis concerning the development of chip-scale light sources. His doctoral dissertation focused on the integration of III-V semiconductor and silicon technologies for miniaturised light sources to be used in compact optical gas systems.

Now, he continues his research on deploying these chips for light-based gas sensors as a postdoctoral researcher in a study that brings together the Optoelectronics Research Centre (ORC) at Tampere University, the VTT Technical Research Centre of Finland, and Vaisala, a global leader in weather, environmental, and industrial measurement solutions.
