A polarization locked optical fiber having a fiber core suspended by a thin cladding web within a tube with a prestress acting along the web to fixedly polarize the core. Preferably, the tube and web are glass materials having different thermal characteristics to provide a built-in stress upon drawing of the web and tube assembly. In the preferred method, an optical fiber preform is machined to a rectangular form and drawn within an enclosing tube to provide the stressed web arrangement. |
