Single-mode fiber length for wavefront filtering
Single-mode fiber length for wavefront filtering
Stellar nulling interferometry offers the possibility of direct imaging of extrasolar planets necessary for the detection of extra-terrestrial life. Achieving optimum performance from the interferometers requires that the wavefronts of light reaching the interferometer are free of distortions. This is achieved by using single-mode fibers, which are excellent wavefront filters. In this paper, we present an improved theoretical model to estimate the minimum fiber length required to achieve a certain degree of filtering and show that the effects of both the fiber characteristics and launching conditions of the input optical field should be considered to determine the minimum length.

Abstract
Stellar nulling interferometry offers the possibility of direct imaging of extrasolar planets necessary for the detection of extra-terrestrial life. Achieving optimum performance from the interferometers requires that the wavefronts of light reaching the interferometer are free of distortions. This is achieved by using single-mode fibers, which are excellent wavefront filters. In this paper, we present an improved theoretical model to estimate the minimum fiber length required to achieve a certain degree of filtering and show that the effects of both the fiber characteristics and launching conditions of the input optical field should be considered to determine the minimum length.
