Abstract

We design and fabricate a two elliptical cores hollow optical fiber, which has an about 60μm diameter hollow air hole centrally, a 125μm diameter cladding, two 8μm/4μm (major axis/minor axis) elliptical cores, and a 2μm thickness silica cladding between core layer and air hole. Its mode birefringence is consisted of geometry birefringence and self-stress birefringence. Based on the finite element method the birefringence characteristics are analyzed numerically at 200nm- 1800nm wavelength. We expect that the two elliptical cores hollow fiber has some potential applications in in-fiber interferometers with polarization maintaining, poling fiber and Bio-sensor based on evanescent wave field.
