Integrated Photonics and Nanoelectronics - IPN

The work in IPN has a strong focus on semiconductor technology development and developing novel device architectures for electronics and photonic components. In addition, we enjoy exploring different characterization techniques to get a better understanding of the device physics. To this end, we collaborate with a number of excellent researchers internationally.

IPNgroup

The IPN research group is led by Kirsten Moselund and was established in 2022 when she moved from IBM to academia. She currently holds a double affiliation with PSI as head of the Laboratory of NanoQuantum Technologies (LNQ) and as professor of electronics and microtechnology at EPFL, on the faculty of Engineering and Technology (STI). The activities are currently spread between the PSI in Villigen - Aargau, EPFL in Lausanne – Vaud and the campus of IBM Research Europe – Zurich in Rüschlikon Zürich. However, the main research activities are collected at PSI while PhD students are enrolled in the doctoral programs of EPFL.

The work in INPHO has a strong focus on semiconductor technology development and developing novel device architectures for electronics and photonic components. In addition, we enjoy exploring different characterization techniques to get a better understanding of the device physics. To this end, we collaborate with a number of excellent researchers internationally.

Some examples of research projects which were carried out at IBM Research Europe Zurich are shown below. New projects are being shaped at PSI along the same themes.

NEON : Neuromorphic photonics and III-V Electro-Optic modulators for random lasing Networks

The goals of the NEON project are a deeper scientific understanding of the physics of neuromorphic photonic networks, an improved architecture, and finally a path towards higher energy efficiency. The researchers hope to achieve and demonstrate a fully integrated neuromorphic photonic platform with a diameter of only around 100 micrometres.

SUGAR project overview

SUGAR : Sustainable Group-IV Active Photonics Research

The SUGAR project aims to develop a more sustainable photonics platform, focusing on group IV elements (Si, Ge, Sn) that are non-toxic and abundant. The proposal emphasizes sustainability throughout the entire device life-cycle, incorporating life-cycle analysis (LCA) from extraction to end-of-life.

Sustainable Group-IV Active Photonics Research Sinergia Project granted

We are excited to announce that our joint Sinergia Project: Sustainable Group-IV Active Photonics Research (SUGAR) has been approved for funding by the SNSF and will start in the spring of 2024. SUGAR is an interdisciplinary project that aims to develop a more sustainable photonics platform, based on group IV elements (Si, Ge, Sn). The proposal emphasizes sustainability throughout the entire device life-cycle, incorporating life cycle assessment (LCA) from extraction to end-of-life.
