ABSTRACT:
A method of forming an optical fiber defining an axis, the fiber having a dipolar dopant wherein a substantial number of the dipoles of the dopant are oriented in essentially the same direction along the axis of the fiber; the method comprising the steps of providing a vessel having a spinneret, establishing a substantially constant electric (or magnetic) field adjacent to, axially aligned with and downstream of the spinneret, forming a prefiber homogenous liquid mixture of at least one dipolar dopant and at least one polymer in the vessel, extruding the prefiber through the spinneret, drawing the extrudate through the electric (or magnetic) field to generally align the dipoles in the same direction and simultaneously elongating the extrudate while it is still in the fluid state by drawing the extrudate.
