<p>The present invention discloses a method of fiber pulling that the output optical fiber can sense radiation dose with very high sensitivity. In a specific embodiment, the method comprising steps of applying temperature with or without vacuum pressure onto a preform during optical fiber fabrication to form collapsed air holes optical fiber. The collapsed or fused area made in the invented fiber increases radiation dose sensitivity. The output fiber is not limited to any specific diameter, shape, single mode or multimode. The method can be applied for any diameter size, any shapes (flat, circle, hollow or solid), single mode, multi-mode and micro structured optical fibers. Also, the method can be used for doped or undoped or combination of them. The invented fiber can be used for detecting irradiation dose using either thermoluminescence or photo luminescence approaches.</p> |
