Microwave and Optoelectronics Group - Photonics
MOG-Photonics
The Photonic Division of the Microwave and Optoelectronics Group carries out comprehensive theoretical, numerical, and experimental research across the full spectrum of modern photonic devices, integrated circuits, and optoelectronic technologies, including photovoltaics and related energy-conversion applications. Its mission is to develop multiscale, multiphysics, and multimodal simulation frameworks that enable predictive design and optimization of innovative devices.
These tools—many of which originate from the group’s long-standing 25+ years’ experience—are shared with partner research institutes and industrial companies to support device development and to interpret complex experimental results.
The group maintains a strong experimental activity within the Interdepartmental Center for Applied Photonics (Photonext) of Politecnico di Torino, where photonic integrated circuits, quantum dot lasers, and VCSELs are characterized using state-of-the-art optical and RF instrumentation. Many devices conceived and modelled in-house are fabricated in external fabrication facilities and subsequently tested at Photonext, enabling continuous validation of the group’s models and fostering a tight feedback loop between simulation and experiment.
The major research pillars (detailed in the Research Lines) are:
- Advanced modelling of semiconductor lasers
- Silicon photonics Integrated Circuits
- Optical modulators
- GaN-based visible light and UV LEDs
- Simulations of quantum-materials for optoelectronics
- Far- and Near-infrared Photodetectors
- Photovoltaic devices
