Paper Abstract

Small sections of suspended twin-core fiber are used in reflection configurations to create two parallel Fabry-Pérot cavities. Situations where both cores are excited and where only one core is excited are analyzed and compared. When both cores are excited, two parallel and equivalent cavities are formed and an interference pattern with higher visibility is obtained. The structure is also characterized with respect to temperature and a sensitivity of 12.4 pm/K is achieved.
