Abstract
An optical fiber disposed to partially internally reflect optical energy passing therethrough is disclosed herein. The optical fiber 10 of the present invention includes an internal partial mirror disposed to partially transmit and to partially reflect optical energy incident thereon. The internal mirror is effectively realized at an interface I of first and second fiber segments 14 and 18. The first fiber segment 14 includes a first core region 22 which circumscribes a longitudinal axis X. The first core region 22 is of a first cross-sectional area perpendicular to the longitudinal axis X. The inventive fiber 10 further includes a second fiber segment 18 in optical communication with the first fiber segment 14. The second fiber segment 18 includes a second core region 24 which circumscribes the longitudinal axis X, wherein the second core region 24 is of a second cross-sectional area perpendicular thereto.
