FIBER FREQUENCY CONVERTER AND OPTICAL INTERFEROMETER AND METHOD GENERATING OPTICAL INTERFERENCE SIGNAL USING THE SAME

摘要

PURPOSE: A fiber frequency converter and optical interferometer and method generating an optical interference signal using the same is provided to convert a frequency of a proper polarization component so as to process an optical interference signal simply. CONSTITUTION: The first to third through holes are formed at a glass corn(30), a cylindric piezoelectric device(40), and a metal support table(50), respectively. The glass corn(30), cylindric piezoelectric device(40), and metal support table(50) are attached such that the first to third through holes are interconnected each other. A jacket-free elliptic core dual mode fiber(60) penetrates the through holes. One surface of the piezoelectric device(40) is attached to a planar surface of the glass corn(30), and the other surface thereof is attached to the metal support table(50) through a conductive adhesive. The glass corn(30) is attached to the fiber. An AC voltage source(70) is connected to both ends of the piezoelectric device(40) so as to apply an AC voltage having different frequencies(f1,f2).
