Sound recording made with pi-shifted Fiber Bragg Grating as strain sensor.
PhD candidates Swapnil Daxini and Arthur Santos (with early contributions by Dr Deniz Aydin) succeeded in recording sound over 75 km of fiber-optic cable. Their work was published in Optics Express in February 2025.

Screenshot of (not yet Dr.) Adam Bernicky’s opening slide
To no-one’s surprise Adam Bernicky delivered an absolutely stellar defense of his PhD thesis on the analysis of copper concentrates using a custom-built burner and Artificial Neural Network analysis.
Congratulations from all of us.

The ground and excited state potential energy curves of an organic molecule forming a TICT state
As part of her MSc research Sara Joulaei-Zonouz (UVic, MSc 2023) studied an organic dye molecule that was designed to exhibit an enormous solvatochromic shift from a twisted excited state geometry - these excited states are called Twisted Internal Charge Transfer (TICT) states. While the molecule behaved experimentally as it should (we checked!), Sara found out - through a lot of ab initio calculations - that it does all this without actually forming a TICT state. A real twist in that story..!

Beach Day 2023
The LaserLab appreciates photons, waves, and silicates in all forms!
Spending a day at the beach in East Sooke Park was a reminder that there is life outside the lab.

Neural Network Analysis
Flame emission spectra of metals are a common chemistry demonstration; Adam Bernicky takes this to the next level by employing neural network analysis for the spectral decomposition of the flame emission from crushed copper ore concentrates.

Everything you ever wanted to know about measuring refractive indices with optical fibres! Did you know that there were over 1000 papers published on that topic in the last 15 years? We read them all!
The review article introduces common performance metrics for these sensors, compares and ranks the many different designs, and then provides guidelines for building better refractive index sensors.
This was a major portion of Deniz’ PhD thesis and a huge tour-de-force!

These five scientists had a brilliant idea on how to simultaneously record 2D fluorescence spectra and absorption spectra.. Optical measurements of chemical kinetics would never be the same again. They demonstrated and patented this new spectroscopic technique.
You would not believe what happened next!
Read moreUnpacking boxes is fun - but it is more fun if you don’t know what is inside and you don’t have over 50 of them…! After many days of unwrapping our equipment we started setting up the first experiment at UVic and Deniz was able to obtain a signal with our fiber-optic vibration probe and test equipment. Now we just need an earthquake (no, not really)
