Abstract

Fiber based Fabry-Perot interferometers offer high precision calibration lines for astronomical spectrographs such as ELT-MICADO in a compact form factor with remote access. Since the calibration lines are carried in optical fibers, a distribution model is possible at very low costs. The fabrication methods described in this paper can achieve different FSRs and finesse over the astronomical J-, H-, and K-band.
