Abstract

Lensless in-line bandpass filters with low insertion losses and high backreflection losses are achieved with expanded-core fibers. It has been experimentally shown that using a large modal-field diameter of expanded-core fibers can resolve the problem of the trade-off between the insertion loss and backreflection. The reduction in the outer diameter, usually occurring when the modal-field diameter is enlarged to an extent, was suppressed at an optimized heating condition.
