Monolithic Fiber Fabry Perot cavities for spectroscopy — •Florin Hemmann, Carlos Saavedra Salazar, Madhavakkannan Saravanan, Hannes Pfeifer, Deepak Pandey, Wolfgang Alt, and Dieter Meschede — Institut für Angewandte Physik, Rheinische Friedrich-Wilhelms-Universität Bonn, Deutschland

Fiber Fabry Perot cavities (FFPC) have emerged as an interface to enhance light-matter interactions [1]. Fabricating versatile and robust fiber cavities as required for most applications however remains a challenging task. By combining fiber guiding glass ferrules with piezo elements we develop a monolithic FFPC design that exhibits high passive stability and large locking bandwidths combined with a tunability over a full free spectral range.

One promising application of these stable resonators is as a miniaturized system for spectroscopy of gases. We demonstrate the ability to determine various oxygen concentration levels in a prototype experiment.
