Welcome to Ultrasound, Microwaves and Optics!

The Ultrasound, Microwaves and Optics group focuses on both fundamental and applied research in the areas of Nanophotonics, Nanoscopy and Sensor Technology. It has a strong track record in optical waveguide technology for gas sensing, spectroscopy, optical trapping, and super-resolution imaging.

Four prestigious grants from the European Research Council awarded to our group members within the last 5 years best illustrate the excellence in research conducted by the group. This important funding, received by Jana Jágerská, Krishna Agarwal and even twice to Balpreet Ahluwalia, further stimulates cutting-edge, high-impact research with access to modern infrastructure and leading international collaboration partners. In addition, the group is hosting three on-going projects funded by the Research Council of Norway, which are again held by Jana Jágerská – FRIPRO Young, Krishna Agarwal – She’s-got-something,-right?, and Balpreet Ahluwalia – Nano2021, and BioTek2021.

Optical Sensing – Photonic Sensors for Trace Gas Detection
Quantification of methane sources in vast and poorly accessible areas of the Arctic requires new methane sensors,which are sufficiently small to be carried by lightweight planes or drones, and at the same time sensitive enough to detect methane at atmospheric concentrations.

Optical Nanoscopy
As optical nanoscopy has exploded onto the world stage since the 2014 Nobel Prize in Chemistry, so too has Nanoscopy @ UiT. Rising up from a (formerly) small integrated optics group, Balpreet Singh Ahluwalia’s ERC starting grant jump-started the Nanoscopy group in 2015. Now jointly headed by Krishna Agarwal, who received her own ERC starting

3D computational nanoscopy
The 3D computational nanoscopy group works on symbiotic utilization of microscopes and algorithms in order to extend the possibilities for both the instrument and the algorithm and create new avenues for biomedical studies towards betterment of human life expectancy and quality. Beside prestigious grants from EU and RCN, the group’s



Microwave engineering
Microwave engineering pertains to the study and design of microwave circuits, components, and systems. Fundamental physical principles described by Maxwell’s equations are applied to analysis, design and measurement techniques in this field. Recent advances in miniaturized, inexpensive components and digital communications in the microwave. 


Microwave engineering
We are employing photoacoustic and ultrasound modalities in imaging of biological samples with an aim of high resolution and higher penetration depth in biological samples. Photoacoustic microscopy, a label-free microscopy, integrates strong optical contrast and high ultrasonic resolution in a single modality, enabling high-resolution imaging deep inside the tissues.
