Miniature scanning fiber Fabry-Perot cavity device made in a monolithic glass substrate
We report on a monolithic fiber Fabry-Perot cavity glass substrate made by femtosecond laser manufacturing that achieves finesse exceeding 70’000. It enables sub-micron fiber alignment capabilities and active cavity scanning over one free spectral range.
