Fiber cavities with integrated mode matching optics

Fiber cavities with integrated mode matching optics

Abstract In fiber based Fabry-Pérot Cavities (FFPCs), limited spatial mode matching between the cavity mode and input/output modes has been the main hindrance for many applications. We have demonstrated a versatile mode matching method for FFPCs. Our novel design employs an assembly of a graded-inde...
