Stress-induced birefringent single mode optical fiber and a method of fabricating the same

摘要: The stress-induced birefringent single mode optical fiber includes an core having a high refractive index and thermal expansion coefficient. An arrangement formed from material low coefficient is disposed to engage the outer surface of tangentially at opposite ends diameter establish stress therein. Air encompasses remainder provide light guiding cladding for and, hence, itself. may include pair flat plates engaging which are entrapped in circular tube concentric with such that air between cladding. Alternatively, elliptical provided minor axis desired fiber. In this case enclosed
