METHOD FOR CHANGING REFRACTIVE INDEX OF AN OPTICAL FIBER BY APPLYING A HIGH VOLTAGE PULSE TO A LONGITUDINAL ELECTRODE |
摘要 |
A method of temporarily changing refractive index of an optical fiber containing a longitudinal electrode arranged in the cladding of said fiber along and parallel to the core of the fiber, wherein the change in refractive index is performed by applying a high voltage pulse to said longitudinal electrode, said high voltage pulse having a magnitude of at least 100 volts and a duration sufficiently short to prevent melting of the electrode, such that the electrode thermally expands through ohmic heating without melting and exerts a pressure on the fiber core to induce said temporary change of the refractive index. The method is suitably used for Q-switching a fiber laser. |
