Paper Abstract

We present performance reports of a new near-infrared (NIR) Fiber-Fabry Perot Interferometer (FFP) as a precise Doppler radial velocity (RV) wavelength reference. FFPs are monolithic single-mode fiber devices that create emission spectra by interfering light traversing separate delay paths. The resulting interference spectrum provides a rich distribution of narrow lines, ideal for use as a precise spectrograph reference. The FFP has the advantages that the uniform density of emission lines gives a much wider bandwidth over which RV measurements are possible, and the finesse and bandwidth can be optimized for the specific application.
