Integrated Photonics and Nanoelectronics - IPN

The INPhO Laboratory at EPFL 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 LNQ and as professor of electronics and microtechnology at EPFL, it is part of 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, in the long run it is the goal that the main research activities will be 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.

Optical and Electrical Characterization Laboratory

Our Characterization Laboratory supports the testing of photonic and optoelectronic devices. It offers capabilities for measurements in the visible range, including I-V characterization, spectral response, and photoluminescence (PL) analysis.

IPN-setup2

Electromagnetic Simulation Workstation

Our simulation workstation is equipped with a high-performance PC and Lumerical software licenses, enabling advanced electromagnetic simulations. It supports the design and optimization of photonic and optoelectronic devices.

Prof. Chang-Won Lee, from Hanbat National University in South Korea, is joining us as a visiting scientist for four months. Welcome to Switzerland and to the team!

IPN-setup3

Lakeshore Cryostat Installed

A new Lakeshore low-noise cryostat with four electrical needle probes has just been installed in our floor. First measurements are already underway, we are looking forward to exploring its full capabilities!

Annarita di TOMA

Annarita joins the group!

Annarita di Toma, a third-year PhD student from the University of Bari, is joining us as a visiting researcher. During her stay, she’ll be working on reconfigurable photonic devices. Excited to have you join us!

David Rohan Callegari

David joins the group!

David, who recently completed his Bachelor in Physics at EPFL, is joining our group for a six-month internship before his Master's studies. He will be working on the simulation and fabrication of photonic crystal cavities. Welcome aboard!

IPN Setup First Light

First Light in IPN's New Nanophotonic Setup

The Integrated Photonics & Nanoelectronics Team made a fantastic job in the last weeks rebuilding their optical setup at Park Innovaare. Today marked a milestone in the successful restart of measurements, as all instruments of the main micro-photoluminescence setup were tested and the first calibartion taken. The group looks forward to installing all other remaining components and going through a meticulous alignment routine.

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.
