Abstract
Section titled “Abstract”The study investigates a case of a low‐coherence fiber‐optic Fabry-Pérot interferometer with a nanocrystalline diamond (NCD) mirror. The method of achieving double density of interference fringes is proposed by the application of birefringent material in the cavity of the interferometer. It can be used to reduce sample volume in comparison to conventional interferometers. The use of a biocompatible diamond mirror makes it specifically well suited for application in biosensing. The fabrication process and surface characterization of the nitrogen‐doped NCD and boron‐doped NCD films are described. The results of numerical modeling and experimental measurements are discussed.
