Article published in Optics Express about Portable microresonator-based label-free detector

This month, researchers from the ULB published a scientitic article in Optics Express journal about Portable microresonator-based label-free detector: monotonous resonance splitting with particle adsorption.

Whispering gallery mode resonators hold great promises as very sensitive detectors, with a wide range of applications, notably as biosensors. However, in order to monitor the fine variations in their resonances, a costly and bulky apparatus is required, which confines the use of these efficient tools within specialised labs. Here, a new self-heterodyne detection scheme is presented, which allows one to do without spectrometers and finely tunable lasers, paving the way to point-of-care diagnostic tools.
