Label-free imaging of bio-molecules in combination with absorption spectroscopy is essential for observing mechanisms in real time. Analysis of absorption properties for sub-cellular structures is challenging due to their weak interaction with light. Fiber-mirror optical cavities strongly enhance this interaction and enable direct imaging and absorption characterization of nano-scale samples.
To this end, the analysis of cavity properties in the natural environment of these biological samples is crucial. We observe the parameter changes of the cavity in water and air and compare them to simulated data.
